VAZ 2114 power windows do not work

VAZ 2114. Why don't the power windows work?

The fuse and relay are ok, what should I do?
The fact is that after checking the relay and fuse, you forgot that external lighting is also involved in the power supply of the ESP. Personally, I had such a problem, I checked the fuse, relay, removed the door trim and checked the entire circuit. At the service station, the repair took 5 minutes, it turned out that the fog lights, which I don’t have, were burnt out.

2-button power window of the right front door.

3-motor (motor-reducer) for the window lifter of the right front door.

4-motor (geared motor) glass lift of the left front door.

5-button power window of the left front door.

To 5 window relays,

A - to the power source,

In-to the external lighting switch

Of course, the window regulators may not work if something just fell off. Yes, while driving, it also happens that a bolt comes out somewhere. After all, our roads do not really meet the standards. And even more so, if you have electric windows, then the contact may simply fall off. So the reason will have to be found out. And you just need to start by checking whether voltage is supplied to the motor, which raises the windows.

Well, then you’ll have to disassemble the lifting mechanism and see how it works and whether anything got in there.

And only after this is it necessary to check the motor itself. Since it can simply fail.

If the window regulators do not work, both at once, then the motors simply could not burn out and only the fuses of all other circuits and, first of all, the lighting are to blame. Check them and the problem will probably be fixed.

VAZ 2114 can be equipped with either conventional manual (mechanical) window lifters or electric windows.

If we are talking about electric windows, then as a rule (at least quite often) the cause of the breakdown is in the electric motor! [][ 1] which is responsible for raising and lowering the windows, that is, it simply burned out.

The window lift motor on the VAZ 2114 is not dismountable, only replacement.

Perhaps the problem is in the fuse (the most simple failure) the fuse box, like in its predecessors (VAZ 2109, VAZ 2108), is located under the hood.

True, sometimes just replacing the fuse is not enough; sometimes you need to look for the reason why it (the fuse) blows.

Perhaps the wires are shorted to ground, you need to remove the door trim and see what’s wrong, perhaps the insulation of the wires is broken.

Maybe the reason is in the relay, it is located in the same block under the hood, relay K5, here too only a complete replacement is required.

Or there may be a breakdown in pure mechanics, for example, a worm gearbox has failed, or a problem with the cable drive.

The window lifter system on the domestically produced VAZ 2114 car is quite simple and consists of the following mechanisms:

motor or mechanical crank
lifting mechanism with a set of gears
adjustable lifting device

There are several reasons why power windows may not work:

No current reaches the electric motor connector. The cause could be a blown fuse or a break in the electrical wiring.
The problem is in the motor, this is either a loss of current through the electrical wiring or a failure of the motor itself. The motor is removed and current is supplied to it with reversal of polarity; the motor should rotate freely in different directions.
Failure (mainly the teeth are worn out, resulting in the mechanism jamming) of the lifting mechanism. It is not repairable, only replacement.
The bushings on the adjustable device come off due to wear.
The glass has jumped off and rested against something, which is why the mechanism simply cannot raise it (or lower it)
A foreign object has entered the mechanism.

A little theory

Electric windows have long been used by car enthusiasts; they have significantly increased the level of comfort in the car. Naturally, like everything else, this innovation was put into practice by foreign manufacturers. The domestic auto industry picked up this idea much later.

Speaking abstractly, in terms of build quality, foreign manufacturers are head and shoulders above the Russian auto industry (however, there are significant differences in prices, service and components).

What does it mean? Everything is very simple

, a connoisseur of Russian cars will have to constantly struggle with minor (and not always minor) problems that arise, such as broken window regulators.

If your car was equipped with power windows with mechanical handles, then the cause of the breakdown is easy to find. Most likely, someone, driver or passenger, exerted extra effort and the mechanism gave way. In this case, it is necessary to disassemble the car door from the inside; I remove all the trim.

If the electric lift does not work, then everything is also quite simple. The door on which a similar problem occurred should be disassembled in a similar way. The mechanism of electric window lifts consists of a non-separable motor, which can simply burn out and require replacement. There is also a cable with a bar coming from it. Before replacing, of course, it is necessary to check whether an electrical signal is received by the motor.

Perhaps the reason lies not in the mechanism itself

, but let’s say, in a faulty button, or in other electrical equipment. It is necessary to check the fuses that are located under the steering wheel on the right (under the cover, read more in the car user manual).

Fuse F5 is usually responsible for power windows. If the fuse is intact, then use a multimeter to measure the voltage at the motor terminals. To do this, you can use a regular 12V light bulb.

No voltage?

It is necessary to carefully check the wiring coming from the motor, inspect the relay and control unit. Very often, auto mechanics have to see problems with the button that controls the window regulator. Don't fix it, if it's the problem, just replace it.

It's not expensive and won't cause headaches in the future. If there is voltage on the motor, but it does not work, most likely the drive brush is stuck. You can solve this problem by pressing the button and turning the motor axis. If the cable breaks, it needs to be completely replaced.

As you can see, everything is quite simple. The reasons why the window regulator on a VAZ 2114 does not work are very trivial and only require attention. Even a beginner can cope with their solution.

What to do if the VAZ-2114 window regulator does not work

If a problem with the window regulator on a VAZ-2114 occurs while the car is moving, and the driver himself cannot correct the situation on the spot, you need to call a tow truck. The movement of a car when the window has stopped going up or down due to a breakdown, from the point of view of traffic regulations, threatens the safety of passengers and the driver himself. Why does the VAZ-2114 window lifter not work? There are many reasons: lowering is difficult because the fuse has blown, there is a malfunction in the door, etc. This article contains information about the types of failures of window regulators on the VAZ-2114, about methods for adjusting and dismantling the mechanism.

How does the power window system work?

The operating principle is actually easier to understand than you might think. The system motor receives power through the wiring and is regulated by a fuse. Then, when you press the power window switch, the motor rotates. From there, an adjuster inside your window's clutch converts this rotation into an up and down motion.

In manual window systems, the mechanism is almost the same, and the initial rotation is made when you turn the window handle inside the car by hand.

When the parts inside a power or manual window system begin to wear out, it can cause the window to move incorrectly or not move at all.

Device classification

Window lifters on the VAZ-2114 are standard for other models of the Samara series. They are classified by drive type into:

The latter are divided depending on the method of transmission of the motor impulse:

lever;
rack and pinion;
cable

By type of construction:

Each model has its own advantages, disadvantages and price. Standard configurations of window lifting mechanisms on the VAZ-2114 consist of two types. Electric drive mechanisms are installed in front, while the rear doors are equipped with mechanical devices.

Replacement cost

Replacing VAZ-2114 window regulators is cheaper than installing electric mechanisms to replace manual ones. If, in order to simply change the window regulator, you need to disassemble the door trim, dismantle the old mechanism and install a new one, then to install an electric version instead of a manual one, you need to partially disassemble the instrument panel, select a power source and run the wiring from it inside the door. This work requires the intervention of an electrician. Because power cannot be taken from anywhere: the source must match the power of the electric drive, and in the event of a short circuit, the fuses must protect the main wiring of the car. In addition, the power windows must operate when the ignition switch is on.

To summarize, we can say that in the first case, the qualifications of the work are minimal, and it can be done by yourself, without having specific knowledge, while working with an electrician requires a specialist who needs to be paid.

The price of a VAZ-2114 window lifter ranges from 2.5 thousand to 3.5 thousand rubles, depending on the design and manufacturer. But as was said earlier: the lever and rack and pinion options are preferable. If you buy a device for only one side, then the left front window regulator will be more expensive, since it is more in demand.

The most common reasons why the VAZ-2114 window regulator does not work

There is no point in arguing that power windows significantly increase the operating comfort of a car. But most drivers also know that they cause a lot of trouble. By the way, when it comes to the breakdown of the mechanism, we must not forget that the problem may not be in it, but in the glass itself. Over time, the holder or seals wear out, which often leads to a banal misalignment, which significantly impedes the freedom of movement of the glass.

The design of the window lifting mechanism is quite simple, but not reliable. And the fact that the safety block is placed in a place where moisture and dirt can easily get in is also not a plus. As you know, the slightest wear of the insulation can lead to a short circuit and breakdown of the entire system.

The most common reasons why a window regulator fails are the following:

Damage to the components of the control unit.
The contacts have oxidized and the circuit has opened.
Disconnecting the power supply.
The control button has stopped performing its functions.

Yes, most often car enthusiasts are faced with the fact that this component of the window regulator fails.

Broken power window button

Why does the VAZ-2114 window lifter not work? A very common reason for this is that its buttons fail. If the mechanism begins to work at a slow speed after a certain time, the plates inside it may have oxidized. This caused a breakdown in contact: it appears intermittently or disappears completely.

It makes sense to check the version with a broken button, replacing it with a working one. Just swap them. The part is dismantled using a knife or screwdriver. Use the tip to pry it from below and remove it from the chip.

If after installation it turns out that the non-working window regulator began to move the glass, and the working one began to move, on the contrary, then it is worth purchasing a new part and replacing it. If the problem is not with the button, then you need to continue searching for the causes of the breakdown.

One of the reasons for the breakdown of the glass door lift mechanism may be that the relay does not work or the fuse has blown.

Find the safety block under the hood of the car.
According to the diagram, determine the location of the relay itself and the fuse, which make up the links of the electric glass lifting mechanism (ESM) chain.
The legs of the elements must be clean, with a pronounced metallic sheen.
If traces of oxidation, dirt deposits, etc. are found, you need to clean them off. Mechanically or using special means, for example, WD-40.
You can check the relay for functionality in the same way as a button. The working element should be removed from another unit and mounted into the ESP system.
If newly installed parts fail again within a short period of time, then the problem is in the wiring itself.

A breakdown may occur with the lift motor. It either burns out completely, or the worm mechanism inside it fails. In the latter case, the device makes a characteristic sound when the button is pressed, but the glass remains motionless.

Window lift repair

Everyone knows that everything in this life is not forever, and the side window lifters in VAZ cars are no exception. The good thing is that in our domestic cars, the repair of mechanical window regulators is much simplified than in “foreign cars” worthy of imitation. And servicing a domestic window regulator is much cheaper in terms of spare parts than foreign ones. Yes, and installing an electric window lifter is a relatively inexpensive pleasure. To avoid the cable coming off the special guide grooves of the drum, two branches of the cable must be tied in the place shown by arrows in (Fig. 1) Fig. 1 Schematic structure of the window lifter in VAZ1 cars - lifting handle or lowering window; 2 - retainer and lining; 3—special socket; 4—main window lift mechanism; 5 — roller bracket; 6 — special screw; 7 — plate pressing the cable; 8 — special bracket; 9 — the glass itself; 10 - cable; 11 — lower cable roller; 12 - bolt; 13 - cable tension roller This is done if the window regulator is not removed for replacement. Now you can begin removing the window regulator. First, you need general vehicle repair preparation. Next, you need to remove the plates that press the cable and lower the glass all the way. The tightening of the tension roller mounting bolt should be loosened with a 10mm socket wrench, then the tension roller must be moved and the cable removed from it. (Fig. 2)Fig. 2 It is necessary to remove the cable from the remaining three rollers one by one. (Fig. 3) Fig. 3 The nuts that secure the mechanism for lowering and raising the glass should be unscrewed with an 8mm spanner or socket wrench. (Fig. 4) Fig. 4 There is a special technological hole in the inner door panel, through which it is necessary to remove the window regulator with the glass pre-lowered . (Fig.5)Fig.5Then we install the window regulator back. Installation is performed in the reverse order of disassembly. The window lift cable must be lubricated with grease. We untie the wire tied during disassembly, which secures the cable, and then adjust the tension. The cable is tensioned by moving the roller, and then the smooth running of the drive is checked.

Having come to us once, you will forever forget about the breakdowns of your car.

Situations

There are situations where power windows stop working under repeated circumstances.
For example, after driving on a dirt road or bumps, the mechanism begins to move the glass in jerks. When opening the casing, it is sometimes discovered that the wire has come out of the chip or from the connector, or after visiting a car wash, incidents begin with the glass. Perhaps the depressurization of the insulation contributed to the fact that moisture penetrated into the electrical components of the system and short circuits or disruption of communication between contacts began. Chafing of the insulating layer of the wiring is one of the most common causes of problems with ESP. To facilitate diagnosis, it is worth observing what causes the standard fuse F6 to blow.

If this moment is the activation of the lift itself, then, most likely, this place is somewhere under the door trim.
If then, when you turn on the ignition, then it is worth checking the insulation of the wires from the door to the safety assembly block.

One of the weak points is where the bundle of wires goes from under the hood to the door trim.

Dismantling the old unit

If the electrical elements have been more or less decided, then the mechanical part of the problem is much more complicated. The described VAZ models have non-separable ESP structures. They are characterized as the most reliable, but in case of breakdown they require a complete replacement from the owner.

How the structure is dismantled.

Remove the handle and rod.
Lowering the glass, remove the holder.
The glass is raised to the maximum and secured with tape.
Unscrew all the nuts holding the mechanism to the door.
Dismantling is complete and the device can be completely removed for diagnostics.

Next, you will decide whether to repair or replace with a new device.

Major breakdowns of power windows

Depending on the configuration of the car, it can be equipped with both mechanical (manual) and electric windows. It is from which of these options is installed on your car that you should begin searching for the corresponding faults.

Thus, for manually operated window regulators the following types of damage are most typical:

failure of rods (bending of rods when excessive force is applied);
jamming of traction joints;
spontaneous unwinding and loss of fasteners.

It is quite simple to fix all these malfunctions with your own hands; you just need to correctly dismantle the window regulator and carry out repairs (we will tell you how to remove the device mechanism below).

In turn, if the power windows on a VAZ 2114 do not work, then the possible reasons for this may be:

fuse blown (at the same time playing the role of a fog light fuse);
failure of relay K5;
break in the power supply circuit of the lifts;
drive motor burnout.

In this case, you should start your search by checking the fuses designated F5 and F16 (this can be done by replacing them with new ones or by regular “diagnosis”). If the fuses are working, then you should continue to look for the problem; if not, replace them with others designed for the same amperage.

The next thing to check is relay K5 in the power window circuit. To test it, you need to replace it with a known working (new) relay and check the functionality of the device. If a malfunction is detected, the old relay must be replaced.

An indirect, but at the same time, objective way to test virtually any relay is to test it by ear. So, when the power circuit is turned on, the working relay should emit a characteristic click, which indicates its serviceability. If, after applying current, no sound is heard, then the relay has soured and does not work.

The next stage of the test will be to “test” the wires in the power window circuit using a multimeter. If a break is detected, it will be necessary to replace the burnt wire with a new one with the same (or slightly larger) cross-section.

If the wiring is in order, then all that remains is to check the functionality of the electric drive itself. The easiest way to do this is to connect the lift motor to the network “directly”. A failed electric window motor cannot be repaired and must be replaced with a similar one.

If after such a thorough check it is still not possible to find a fault, then you should check the mechanical parts of the electric lift, namely, inspect the condition of its gears. Most often, it is their breakage or chipping/abrasion of individual teeth that causes the malfunction. The solution in this case will be to replace the gears themselves, which can be purchased at almost any auto store.

Gross weight of VAZ 2114. All VAZ carsCharacteristics of the VAZ 2114 car

A good car package includes electric windows. This function is no longer something special, but it is highly valued by car owners for its convenience. But during the operation of the car, there comes a time when the window regulators begin to work poorly - they may not respond to button presses or get stuck from time to time. In order to understand the reasons for this, you need to have knowledge about the power window system, how it functions, and only then start looking for breakdowns.

Causes of window lift malfunctions

The power windows can only be operated when the key is in the ignition switch and turned to the “ON” position. When pressing the power window up/down button does not produce any result, it would be logical to assume that some kind of breakdown has occurred. To troubleshoot a problem, you need to understand the cause of its occurrence. It is necessary to check the window lift system to detect a failed part; To do this, we carry out the following actions:

1. If the power windows do not work, you need to check the circuit breaker or fuse - it may have blown.

2. When only the rear power windows do not work, or there is a reaction only from the main unit (that is, the buttons on the doors do not work), it is necessary to check the presence of voltage at the window regulator terminals.

3. If you have not identified a breakdown in the window regulator system, then you need to look at all the wires that connect the window regulator elements. If a wire break is detected, it must be repaired.

4. If you cannot lower/raise only one of the windows using the main power window control unit, you can try to do this using the buttons located under the door trim. If everything worked out this way and the glass moves, then the problem is in the control unit.

5. Another reason for the malfunction of the window regulators is the inoperability of the electric motor. Then you should check the presence of voltage and wiring, and here you will need electrical diagrams for your machine.

It is worth paying attention to the presence of mechanical damage to the guides along which the side glass moves

Most often, car owners encounter problems with the wiring that connects the elements of the window lift system, as well as electric motors. The main reason for their malfunction is the very active use of window lifters, as well as wear and tear on the wiring. It will take you a lot of time to find a malfunction in the power window system. There is also a backup option - you can always contact a specialist who deals with the electrical part of machines, and he will do everything himself. This option is very convenient if you do not have time to solve such a problem yourself.

We eliminate mechanical failures of power windows

Fewer malfunctions occur with the electrical part of the power window system compared to the mechanical part. The very weak points of window regulators are the plastic elements that are needed for the production of racks, gears and other plastic parts of window regulators. When operating the window regulators, the gear wheel may be damaged and must be replaced.

It is quite difficult to determine this breakdown - you hear that the engine is running, but the glass does not move. Most likely, the gear wheel spins at idle and does not rotate the glass position control device. In order to replace the gear, you need to disassemble the door panels and remove the remains of the gear from there. Then we replace the faulty part. If everything went well and the glass moves, then the door panel can be closed.

The malfunctions of cable window lifters are the same as in manual drives. One of the main faults in such window lifters is a broken cable. Such a malfunction may occur due to the expiration of the device’s service life or a sudden temperature change in winter. When the cable breaks, it needs to be replaced with a new one. The last type of malfunction is the breakdown of levers, but this type is quite rare. However, if it happens, then the levers must be replaced with new ones.

Removing window regulators

Having talked about malfunctions and the principles for eliminating them, we will now figure out how to remove the window regulator of a VAZ 2114 (after all, without dismantling it, it will simply not be possible to inspect and repair the mechanism).

Despite the fact that manual and electrified lifts have completely different designs, they are installed according to the same principle inside the door technological cavity of the car.

Their removal should be carried out as follows:

Remove the door trim.
Raise or vice versa - lower the glass so that the fastening bolts of the glass frame appear in the upper hole of the door.
Unscrew the two mounting bolts securing the glass in the frame.
Lift the glass as high as possible with your hands and secure it with plastic or wooden wedges.
Lower the lift slider to its lowest position.
Unscrew the 4 nuts securing the guide (for the rear door, unscrew the 2 nuts securing the guide).
Unscrew the 3 nuts securing the window lift mechanism (for the rear door, also unscrew the 3 nuts holding the window lift).
Remove the window regulator through the technological opening in the door.

Installing a new device is done in exactly the same way, but in reverse order.

If the VAZ 2114 electric window regulator is being replaced, then before starting it you should disconnect the terminals from the battery so as not to cause a short circuit.

Also, to extend the life of lifts (both electric and manual), when replacing or repairing them, all joints and moving elements should be lubricated with CV joint grease or similar.

In conclusion, I would like to add that an important key to the long service life of lifts is their periodic inspection and maintenance.

So, if you have to exert considerable effort when opening/closing a window with a manual window lifter, or if the electric lifter begins to close the windows with great difficulty and creaking, then you do not need to wait for them to completely break down - you should dismantle these devices, tighten the fasteners and lubricate all moving parts.

How to open a window when the SP is not working

Sometimes problems arise on the way, and the possibilities of self-diagnosis, and especially repair, are significantly limited. How to raise the window in such cases if the window regulator refuses to work? We have put together a small selection of tips that will help you get out of this unpleasant situation with honor:

A screwdriver or pliers are enough to remove the door trim. This will allow the glass to be disconnected from the actuator, after which it can be raised or lowered by hand. To fix it in the upper position, the glass will have to be supported with something suitable, at least with a stick. In this condition, you can operate the machine for several days until it becomes possible to carry out a full repair;
It is often possible to lift the glass manually by holding it between the palms of your hands and pulling upward with force. If the edge of the window is not visible, you will need to remove the rubber gaskets, and if this does not help, proceed to the previous step;
Often the inoperability of the joint venture is caused by a banal discharge of the battery, especially after a long period of inactivity. The problem is solved by recharging the battery. You can try to “borrow” it from a neighbor, at least to raise the glass. But if you are in a hurry, and there is no compassionate neighbor, try pressing the “Up” key with high frequency - sometimes the glass actually begins to rise a little;
You can raise a lowered window if the window lifter does not work using a barbaric method called “fishing”. It consists of using a fairly strong hook that squeezes into the gap between the door and the window. By moving it down/up and to the sides, you can hook onto the actuator and try to pull the glass up with this hook;
if the joint venture does not respond to your actions, you need to check whether power is supplied to the electric motor. This is done as follows: turn on the ignition, and then turn on the overhead lamp, then press the window lifter button. If power is supplied to the motor, the intensity of the glow will decrease momentarily. In this case, you can try to revive the engine by pressing the ESP button and hitting the handle with which you open the door with your fist with considerable force. Sometimes this helps - if the reason lies in the wedging of the worm due to worn teeth of the plastic gear of the gearbox. This usually happens in the extreme (usually lower) positions of the glass;
If the window regulator does not go down, the reason may be a broken electrical wiring. In such cases, it is necessary to open the door and remove the casing with wires. To check the lack of contact, you will need the help of a friend who will press the SP button, and at this time you will pull each of the wires in turn. If the glass moves, you have found a malfunction, and you can even fix it yourself;
if you are convinced that the motor is intact and the problem is not a faulty gearbox (if the window goes down normally, without jerking or suspicious sound effects, but does not want to go up), try rearranging the wires going to the motor, and then press the “Down” key . If the glass rises, you can lower it before repairs can be made by repeating this procedure.

We hope these tips will help you temporarily solve the problem of your power window not working.

Inoperative window regulators: causes and methods of troubleshooting

Electric windows (EP) are one of the vehicle elements that contribute to more comfortable driving. Like any other electrical circuit component, EDs tend to break down periodically. What to do if a car window regulator does not work and for what reasons these components break - read below.

Principle of operation

Why do the power windows not work or only the right window does not go up? To understand exactly why the malfunction occurred, it is advisable to familiarize yourself with the operating principle of the unit. Typically, such a system has a trapezoidal design, which allows the windows to be raised and lowered by pressing switches. The buttons themselves can be located in all car door cards or located only in the driver’s door. It is also worth noting that an electric motor is mounted in each door, which operates in two directions.

In addition, each system is equipped with a special relay, the purpose of which is to control the voltage supplied to the electric motors of the structure. Depending on the vehicle, some car models may be equipped with automatic switches that are installed separately for each electric motor. The use of such structural elements makes it possible to ensure normal operation of the entire system if the window regulator is poor on only one door.

How to connect a button?

The driver and passenger door buttons are connected to each other, as well as to the ESP motor and power cable. Correct pinout of the power window button:

Pin 1 on the driver's door is connected to pin 6 on the passenger side. Contact 1 on the passenger door is connected to the negative terminal of the ESP motor.
Pin 2 on both buttons is connected to power.
Pin 3 is the ground on the driver's side and the positive wire on the passenger's side.
Contact 4 in both cases goes to the headlight switch.
Contact 5 is ground in all cases.
The positive wire of the ESP motor corresponds to pin 7 of the passenger door button.

Causes of malfunction

So, we gradually approached the issue of malfunctions. What if the window regulator cannot go down or up? Before you remove the window regulator, disassemble and repair it in your car, let's look at the main reasons. If the rear or front windows do not work, the reason may be either electrical or mechanical.

Detailed design of the EP system

Electrical faults

First of all, if the window regulator has stopped working, it is necessary to diagnose the safety element responsible for the functionality of the system. If you realize that the power window is not working due to a fuse, then you just need to replace it. But if the fuse is working, then you will need to measure the voltage at the electric motor terminals. This task can be accomplished using a regular 12-volt lamp or using a tester.

If you find that the driver's window or any other door does not work due to voltage, then you need to further check:

wiring;
relay;
system control unit.

Sometimes a car owner thinks that the window regulator is broken if, after opening the window, it automatically begins to close until the key is turned in the ignition. As a rule, in this case the problem lies in the contacts, which should be cleaned. Much less often, but it still happens that repair of electric windows includes replacing or repairing a button.

Mechanical defects of the mechanism

If, after measuring the voltage, you realize that there is current in the system, but it does not go down or the window regulator does not work at all, most likely the problem is mechanical. As a rule, in this case, something is interfering with the device, so you will have to disassemble the door and look for the reason. Much less often, the reason lies in a failed electric motor (the author of the video is the channel In Sandro’s Garage).

How to raise the glass if the electric seal is broken - there are several options:

Purchase a window regulator repair kit and repair the device, after which you can fully use the system.
Try to grab the glass on both sides with your hands and pull it up. If the glass falls after being lifted, you will have to disassemble the door and place a support of the appropriate size under it.
If you can’t lift the glass with your hands, you can take a fishing hook on a fishing line and lower it into the door card. You need to try to pry the glass and lift it.

Basic malfunctions of window regulators

Repair manual for VAZ 2108, 2109, 2114, 2115 Wires and fuses

The main principle of operation of electric windows is that they cannot be used if there is no key in the ignition switch, which must also be in the “ON” position. When this condition is met, but when you press the window button the windows do not go up (or, if they were closed, they do not go down), this indicates that there is some kind of malfunction. Diagnostics of the mechanism, aimed at finding a breakdown in order to eliminate it, is performed in the following order:

First, you should check the functionality of the circuit breaker and the integrity of the fuse - often it simply blows due to excessive load;
if the mechanisms located only on the rear doors refuse to rise/lower, while the main unit shows signs of life (window lifter door buttons do not work), you need to check with a tester whether there is voltage at the input terminals of the mechanism;
if the diagnosis of the window lifting mechanism does not produce results, you should carefully check the electrical wiring - if damage is detected, the integrity of the wire must be restored;
if there is a problem with controlling one of the four windows using commands sent from the main control unit, perform the same operation by pressing directly on the door buttons. The glass began to move, which means it’s all about a faulty or faulty ECU;
Very often the window lifter mechanism does not work due to a breakdown of the electric motor. Testing should begin with the terminals, which are checked for the presence/absence of voltage; you will also need to check the electrical wiring, which will require a detailed diagram of the electrical equipment of the car;
It is likely that the window moves jerkily or even stops due to the appearance of mechanical defects on the guides that are used to move the glass. It is possible that a large amount of dirt and dust has simply stuck to the guides, which over time have hardened so much that they do not allow the actuator to move freely.

Note that the most common causes of ESP failure are breaks in the wiring connecting the units and window lift systems, as well as breakdowns of the drive motor itself. These malfunctions usually appear when the mechanism is used excessively. Please note that if you have never dealt with window lifters before, troubleshooting on your own may take a lot of time. Therefore, if possible, entrust this work to a professional who specializes in electrical parts

This will cost more, but if you take into account the time factor, the losses may not be significant

Strictly speaking, problems with the electrical part of these components occur much less frequently than mechanical breakdowns. The obvious weak point of the joint venture is the plastic parts that are used in gears, racks and other elements of the mechanism. The gear wheel is subject to increased wear, and its inoperability is easy to determine - if the motor is running, but the glass is rooted to the spot (twitching may occur). In such cases, the wheel will need to be replaced, which will require removing the door panels. If the wheel has fallen apart, you need to find and remove all its fragments, then remove the old part and install a new part. In a joint venture with a cable mechanism, a frequent breakdown is the cable breaking due to its wear, as well as with frequent exposure to large temperature changes (for example, in winter). If the cable breaks, the problem is solved by replacing it. Relatively rarely, the inoperability of the window lifter occurs due to breakage of the levers, which should also be replaced with new ones.

Instructions for replacing the electric motor

Repairing a window regulator may include different stages depending on the breakdown. In this case, we will tell you how to repair a window regulator by replacing its electric motor; as mentioned above, this problem is one of the most common.

The replacement process is considered using the example of a Lada Kalina car:

First you need to buy a new electric motor, which is sold in a housing with a gearbox. The door trim is dismantled - this operation cannot be performed in the cold, since the trim is fixed using plastic pistons, which will quickly break.
Unscrew all screws and other fasteners securing the inner handle.
All wires must be disconnected; for greater convenience, you can remove the speakers. After these steps, the glass, which is fixed in the guides, is unscrewed. In order for the glass to sink to the bottom, you need to unscrew four more screws; to do this, use a 10 key. There is a curtain at the bottom of the glass unit, which must be removed.
The window regulator itself is mounted on nuts and guides, the electric motor itself is secured with three more nuts. The block can be pulled out through the technological holes in the door. If you disassemble the gearbox, the electric motor will fall apart into two parts. In general, the gearbox must be dismantled and replaced with a new one, further reassembling in the reverse order. The gear cable should be lubricated before use.

VAZ 2114 power windows failed

Suddenly the power windows on the VAZ 2114 stopped working, the fuse was intact on both doors, I removed the relay, rang it - it was intact. According to the electrical diagram, the plus fits separately for each door, the minus for each door. There is one plus for the backlighting of the buttons and for the opening buttons themselves, the buttons light up, therefore there is a plus.

What could be the problem?

It's easy and interesting to communicate here. Join us!

you pick the button out of the door, turn on the ignition, and call the wires right on the button, there are 2 pluses, two minuses, and two for the motor, + one for the backlight, everything is very simple

Great answer above! How did you check the relay? It is tested in the closed and open state. In general, it works when the ignition is turned on, it’s not difficult to check by clicking. Well, check if power is coming out of the mounting block. The backlighting of the buttons is usually powered by turning on the headlights. Total weight. As a rule, two buttons do not fail at once.

I'm tired of writing, these advisers who write to any question about electrical engineering: - there is no mass! ! !look for your mass elsewhere, the person needs help and you are here. Dear Nikolai, all negative things come to us suddenly! ! !

Since you have knowledge of the electrical part, it will be easier for us to explain, this is good.

Most often, malfunctions of this type come from the power window control unit, or simply from the buttons

let's divide the circuit into 2 parts and check each one separately,

1 disconnect the plug to the buttons and disconnect the wires going to the window motor, check the motor using + and - connected separately, you can use another battery, check the plug to the buttons with a simple light bulb, if both here and there everything is normal, then the reason is in the buttons, or rather in the jumper plastic contact type swing

if you have any questions, please sign up, today my advice has already helped 2 out of 2 people, and the presence of working backlighting in the buttons does not indicate the working condition of the button itself, the system is like a regular switch in our home

How does a window regulator work?

The window regulator is a simple metal track bolted to the inside of the door. It takes the rotational movement of a crank handle or the movement of a window lift motor and turns it into a vertical movement.

There are two types of window regulators. Classic cars usually have a parallelogram type that looks like a pair of scissors when in motion. Crank mechanisms rotate the angle of one adjuster arm, causing a pivot point and moving another arm connected to the window track, which in turn moves the window up or down.

The modern electrical regulator is a cable system. An electric motor moves a cable through a pulley system that raises or lowers the window, like a tiny drawbridge. While both systems are reliable, they have several parts that can wear out.

Note: Power windows are a convenient option for opening and closing windows that have become universal in recent years. Even the cheapest cars on the market, like the tiny Mitsubishi Mirage, have available power windows. Instead of having to lift the window yourself using a crank, you simply press a button and the servo motor starts rotating a gear connected to the regulator or cable system.

Tips for motorists

As standard, on a VAZ-2114 car, only two window lifters are installed on the right and left sides of the front doors. If a malfunction is identified due to the failure of both power windows, you will first have to check the thirty-amp fuse F6, located in the mounting block under the hood of the car.

If it is burnt out, then it needs to be replaced with a new one. Well, the driver will have to look for the reason for the failure of this fuse, because if this is not done, then the new fuse will burn out in the same way. When searching for a short circuit, it is necessary to take into account at what point the fuse blows. If this happens when the power window is turned on, then most likely there is a short circuit under the door trim, and if the fuse burns out immediately after the ignition is turned on, then most likely the wiring is shorted to ground, somewhere from the mounting block to the door trim.

The weak point that leads to chafing of the insulation of the wires going to the electric window lifter motor is the transition of the bundle of wires from the passenger compartment under the door trim. Therefore, this place needs to be checked first.

If the fuse is intact, then you will have to remove the door trim and check the voltage at the contacts in the plug connectors of the wires suitable for the window lift motor. This can be done very simply using a test light (one wire to the contact, the second to ground, if the light is on, it means there is voltage). If there is voltage and the window lift motor is not working, it will have to be replaced.

In addition to the fuse, the cause of the window regulator not working can be the failure of the K5 relay located in the mounting block. A relay that is not working is usually replaced with a new one. Sometimes, the window lift motor stops working as a result of warping of the thermobimetallic fuse built into the motor to protect it from overloads.

Also, the cause of a non-functioning window lifter can be mechanical faults. These include: failure of the worm gear, which serves to reduce the rotational speed of the electric motor shaft, and problems associated with the cable drive. During operation, the window lift cable stretches and increases in length, which leads to incomplete lowering of the side window. In addition, the extended cable can jump off the guide rollers and then there is nothing to move the side window.

Electrical problems

It is better to start diagnosing a malfunction by checking the condition of the fuse, which is responsible for the operation of the power windows in the VAZ 2110. Usually it is numbered F5. If necessary, the fuse must be replaced with a new one. If it is intact, proceed to the next stage. You will need a 12 volt light bulb with two wires going to its positive and negative side.

Connect the wires to the terminals of the window lift motor and press the button. If the light comes on, the wiring is good, but if not, start looking at the wires for breaks. Also don't forget to check the corresponding relay.

Another problem with the electrical wiring circuit is when the window opens when the button is pressed, but when it is released the glass rises again. In some cases, the button does not work until you turn the ignition off and on. These signs indicate a malfunction of the button, so you can try to remove it and clean the contacts, and if necessary, replace it with a new one.

The window regulator slowly raises the glass - what should I do? There is a solution!

Hi all! Dear friends, you are all aware of what “jambs” and shortcomings each of us “happy” owners of domestic VAZ cars have to eliminate. Today’s article is another life-saving solution for those who are faced with the problem of poorly functioning beet lifters.

Electric windows (ESP) have been installed on foreign cars for decades, so, as a rule, there are no problems with them, which cannot be said about VAZs. On “our” swallows, such a miracle has been occurring for about 10 years, and as practice shows, the good old “meat grinders” in the form of a simple mechanical handle worked much more reliably. Get to the point! A defect was noticed on many models from 2109 to 2115, where, as a rule, the front right glass does not rise well. Moreover, the window lifters slowly raise somewhere from the middle or even lower, the glass slows down or stops rising altogether. At the same time, drivers help the ESP either with their hand or with a “clarion word”.

Why does the window regulator work poorly?

The first reason is poor lubrication of the window lift mechanism. During operation, the ESP mechanism gradually loses lubrication, causing the windows to slowly lower or rise. The solution to the problem is to remove the door card, after which all working parts are lubricated. If after lubrication of the window lifter mechanism the problem is not eliminated, we continue to search for it.
Often the reason may be poor adjustment of the glass itself. That is, a situation where the glass itself is not installed correctly on the lifting bar. In this case, it is necessary to remove the door card and adjust the position of the glass using the adjusting nut, and then check the operation of the ESP.

Factory defect. If everything is ok with the mechanism and the glass is in place as it should, I advise you to check the guides along which the glass itself moves. That is, we are talking about a tunnel in which glass flows. As bitter experience shows, it is this manufacturing defect that often becomes the reason why the window lifter slowly raises. Due to the narrowing of the guides, additional resistance occurs, as a result of which the motor slows down and the glass slows down. Your task is to understand exactly where the resistance arises and try to correct it. The work is quite simple and consists of removing the velvets and slightly expanding the narrowing area of the metal.

The fourth reason is poor lubrication of the guides. Sometimes, during operation, the guides, or it would be more correct to say the tunnel along which the glass moves, wear out, become abraded, become dirty, etc. As a result, the glass experiences excessive load and resistance, which naturally leads to the window lifter slowly raising the glass. The problem is solved quite simply, we take cotton swabs and clean the tunnel from dirt and sand. Then we take a lubricant, it can be silicone grease or WD-40, or something alternative, and lubricate the guides. We don’t skimp on the lubricant, but we don’t put it in excess either, we just generously coat the sliding areas of the glass, then check the result.

Wear of velvet. Due to increased wear of the velvet covers, or more simply put, glass seals, the latter may rise more slowly. However, if this is the problem, then most likely the power windows on all doors will not work well. The solution to this problem is to replace the worn velvets, after which the problem should go away.

The electric window drive is faulty or has poor contact. If there is something wrong with the motor that raises the window or there is poor contact in the connections, then you cannot avoid problems with raising and lowering the windows. Incorrect operation of the drive, as a rule, manifests itself in both directions, that is, raising/lowering, but most often, lowering is more difficult. In order to fix this problem, it is necessary to remove the electric motor, check its serviceability, lubricate it, etc. After this, we check the operation of the ESP again.

If all the steps described above are completed, then the problem should most likely go away; if this does not happen, you should continue the search or completely replace the ESP. That's all for me, I'm waiting for your solutions to this problem! Perhaps some of you have encountered a situation where the window regulator does not raise well, I would be grateful if you describe your case, as well as a way to solve this problem. Bye!

What is the cause of the problem

Sometimes there is no malfunction as such. For example, window regulators may fail in severe frost, but other electrics also suffer from similar problems. Therefore, experts advise not to save on buying/renting and heating a garage. But mechanical failures are much more common.

If you suspect a breakdown, you first need to check the TsBKE - this is AvtoVAZ’s personal innovation, which operates the electrical package. First you need to make sure the fuse is working. If everything is fine, we disassemble the doors, arm ourselves with a multimeter and measure the voltage at the terminals of the window lift motor. If there is no voltage, then:

There may be a malfunction of the power window control unit (the button for opening and closing the window located on the door).
The problem lies in the connection of the wire connectors.
CBKE refused.

The window lift motor is stuck or stuck.
The window lift cable has already outlived its usefulness and needs to be replaced.
Distortion of the glass itself, while the rest of the system is in full working order.

All of the above breakdowns occur with approximately equal frequency, with the exception of glass distortion, which occurs much less frequently.

Self-detecting a broken power window can be seriously difficult. First, it is difficult to diagnose a CBCE problem. The device is designed in such a way that one of the cables is multifunctional. It could be:

X1-4.
X1-6.

The essence of multifunctionality lies in the fact that some conductors are capable of independently changing polarity if the appropriate command is received from the CBKE. These pairs can simultaneously control side mirrors, central locking, provide power, etc.

To diagnose a malfunction of the CBKE, it is necessary to perform the X1-4 or X1-6 test, which is multifunctional on a specific vehicle. In this case, you should also press the window up/down button. If the multimeter detects the presence of electricity when the button is activated, then everything is fine. You also need to check sockets No. 1, No. 5, No. 11 and No. 13. If in all cases the presence of current and correct operation of the system are noted, it means that the reason does not lie in the CBKE.

As for the power window control unit, you most likely will not be able to identify the fault yourself. The fact is that it ensures the operation of all such devices in the car, which means you can call it as much as you like, but it will be very difficult to confirm the fact of its failure and find out where exactly it failed. The only real way out in such a situation is to contact specialists at a service station. With a high probability, it will not be possible to do without diagnostic equipment.

Repair is determined by the specific malfunction and is not always possible at home. If we are talking about skewed glass or poor conductor contact, this is not a problem. You can also replace a worn-out window lift cable yourself; you just need to purchase a new one at the nearest car market. If the problem lies in the power window control unit or in the CBKE, then you cannot do without contacting a service center. In this case, independent electronic repair is impossible.
