Repair of trapezium wipers VAZ 2110 - replacement of trapezoid wipers

The design of the windshield wiper on the VAZ 2110 is quite reliable and during normal operation the motor and the trapezoid itself can easily move all 300,000 km, which has been proven by the personal experience of many owners. But there are also exceptions to the rules.

It often happens that the splines are bypassed or the trapezoid structure simply breaks down. If you have such problems, the repair procedure will be discussed below.

To replace all the wiper parts, we will need the following tool:

• flat and Phillips screwdriver;
• 10 mm socket head;
• ratchet handle;

To do this job, you first need to do some preparatory steps, namely:

1. Remove the windshield trim (jabot).
2. Remove the insulation and seal under the hood.
3. Disconnect one end of the expansion tank rubber and move it to the side.

When all the preparatory steps are done, everything will look something like this. The arrows at the top show the attachment points of the two nuts:

You need to unscrew them, of course.

After this, we disconnect the clamp securing the expansion tank and, lifting it up a little, move it to the side to gain access to the third trapezoid mounting nut.

After this, the nut can be unscrewed; it is located at the very bottom:

After you have dealt with this, you can carefully turn the trapezoid and remove it from the left side, slightly bending the metal frame below the windshield to the side (the force required is very small - there is no point in talking about any real bending!)

And lift it almost all the way to take it out:

All that remains is to disconnect the power plug:

And now you can finally remove the entire structure of the trapezoid and the wiper motor from the bore. If you need to disconnect and replace one motor, then in principle there will be no difficulties with this - just unscrew it and replace it.

Installation of all removed parts occurs in the reverse order. It is worth mentioning the prices of these spare parts. The cost of a trapezoid assembly with an engine for a VAZ 2110 is about 2000-3000 rubles from the manufacturer AvtoVAZ. Chinese analogues cost about 2000 rubles.

Signs of Brake Pad Wear

As the vehicle's mileage increases, the need to replace the front brake pads on the VAZ 2112 also increases.

Remember! The front pads wear out much faster than the rear ones, since the main braking force falls on the front of the car.

Below are some signs that can help you determine if you need to replace your front brake pads:

• The first is a squeaking sound when braking. Such sounds irritate absolutely everyone on the road - from the driver himself to pedestrians passing by. The creaking indicates several causes of problems with the pads.
• The first reason for a squeak is, of course, wear on the brake pad. The fact is that it is made of metal on which a friction lining is attached, which, in fact, brakes the brake disc.
• When this friction lining wears off, the metal of the brake disc begins to rub against the metal of the pad and creates this nasty squeaking noise.
• The second reason for squeaking is poor quality pads. The friction lining may be made of low-quality material, which creates such sounds when braking.
• The second sign is a deterioration in braking force. In simple words, you need to press harder on the pedal so that the car brakes as much as before.
• The third sign is a sinking brake pedal. If the brake pads wear out significantly, the pedal will sink, that is, operate closer to the floor. Conversely, after installing new brake pads, the pedal will most likely rise to its previous normal position.

Here are the signs that the front brake pads on a VAZ 2112 need to be replaced.

Wipers do not work on VAZ 2110

If it's snowing or raining outside, wipers become indispensable elements of the car.

Wiper elements for VAZ 2110

In our material we will talk about the mechanism of the VAZ 2110 wipers, discuss the main reasons for their malfunction, the issue of repair and the search for alternative options to standard windshield wipers.

How to care for your wipers to extend their lifespan

To ensure that your wipers last as long as possible, follow these tips:

• Wipe dirt-stained brushes with a clean, damp cloth or sponge. This way you will not only get rid of dirt, but also protect the glass from scratches.
• If the front glass is covered with a layer of dust and the car washer fluid has run out, do not turn on the cleaner. This will also cause scratches on the glass.

• In winter, especially during snowfalls, do not leave the wipers leaning against the windshield - they will freeze. It is better to raise the leashes so that the brushes are suspended.
• If the windshield wipers are still frozen, do not under any circumstances try to tear them off by force. This will only damage the rubber band. Start the engine, turn the heater on to blow the windshield and wait until it defrosts.
• You should also not knock ice off the frame or brush. Gently bend the elastic until it peels off in small pieces.
• When replacing wipers, place some thick cloth on the windshield. This will protect it in case the spring-loaded leash slips out of your hands.

The trapezium of the wipers transmits the force from the engine to the windshield wiper arms. The best quality of windshield cleaning will be only if all elements of the wipers are in working order. If the trapezoid hinges are clogged with dirt or the lubricant has dried out, the motor energy will not be enough for proper cleaning. Therefore, owners of cars of the tenth family are forced to repair the trapezoid once every 5–10 years in order to avoid deterioration in the performance of the wipers.

Device design

Wiper circuit

First, let's try to understand how the windshield wiper circuit on the VAZ 2110 works and what components form a solid unit called a windshield wiper.

Refinement stages

Wiring It is easy to modify or replace wipers. To do this you need to take several sequential steps:

• Disconnect the negative cable from the battery;
• Pull the wiper towards you;
• Remove the existing brushes;
• If there is a decorative trim, remove it;
• Unscrew the mounting bolt, thereby removing the old wiper;
• Compare the dimensions of the old and new cleaner;
• Ideally, the new device should not exceed the old one by more than 20 millimeters;
• Reverse the assembly procedure.

As you can see, changing windshield wipers is not difficult. But with the repair procedure, everything is somewhat different. But following the instructions, even an inexperienced VAZ 2110 owner will be able to do everything with his own hands.

Why the wipers don't work

At some point, the car owner may notice that his wipers are not working. This may manifest itself in their complete stop or creaking operation.

Trapezoid Compatibility

First of all, look for the reason in the electric motor. But remember that mechanical problems also happen.

The most popular mechanical breakdowns of wipers:

• When the cleaners turn on, the sound of the motor is heard, but the brushes do not move or twitch slightly. Most likely, the nut securing the crank to the gearbox axle has lost its grip or has become completely unscrewed.
• Non-synchronous operation of the windshield wipers indicates a problem with the drive. Again, check the locking nut. When tightening the nut, be sure to first place the brushes in the correct position.

As for problems with the electrical component, they manifest themselves as follows:

• The wiper moves very slowly, stops, then starts working again, does not stubbornly go to the lower position. Check the limit switch. By bending the contacts, it is adjusted in this way. If such a measure does not bear fruit, replace the entire VAZ 2110 wiper motor assembly, since the gearbox is built-in;
• You have turned on the intermittent mode, but the brushes work non-stop. Here the problem lies in the relay, which needs to be replaced. If when you turn on the device you do not hear a sound from the rotation of the motor armature, then the relay is 100% to blame. If not, then check for burns and oxidation on the contacts;
• When choosing any mode, you can only hear the clicking of the thermometallic fuse. At the same time, the anchor and brushes remain in place. Check to see if the brushes are frozen because of the frost and that’s why they don’t move. Either fuse F5 has blown, or the armature has burned out;
• The electric motor does not turn on, although the fuses are good. Check the quality of contacts. This often causes a stuck brush or a burnt armature.

How to determine that a trapezoid is “kirdyk”

Kirdyk is a slang word meaning an extremely bad situation.

It happens that the retaining ring of the bushing breaks and the rod simply flies out.

The slightest disturbance in the operation of the trapezoid can lead to incorrect operation of the wipers. Usually this part is replaced with a new one, although in some cases you can get by with installing a repair kit. Its cost is significantly lower than the price of the entire part, although repairs will take much more time. Here is a list of the main signs by which you can determine that a part will soon fail:

1. Windshield wipers begin to do their immediate job poorly. This occurs due to the weakening of pressure.
2. An unusual noise is heard during operation.
3. A backlash appears, which can be determined even visually, since the glass will be difficult to clean.
4. It happens that the brushes move in one direction easily, but back with difficulty, constantly slowing down.

All these problems lead to the fact that the windshield remains dirty, with streaks and smudges.

Repair kit for VAZ-2110

Most often, plastic parts are destroyed in the trapezoid. In this case, a repair kit can help.

When purchasing a repair kit, pay attention to the part number. If metal parts are damaged, you will have to replace the entire trapezoid. As a rule, the trapezoid is destroyed as a result of an accident, or due to careless handling of the windshield wiper system

Windshield wiper repair

In practice, repairing wipers on a VAZ 2110 is not at all difficult if you have at least basic experience in working with a car and its electrical components.

Unscrew the fixing nut

First, let's figure out how to remove the wipers on a VAZ 2110. The design provides several fasteners, by unscrewing which you can easily remove the wipers themselves.

But with disassembling the windshield wiper assembly, everything is a little more complicated. It is analyzed as follows.

1. Remove the dashboard.
2. On the left side, find the relay that is attached to the body. If it is broken, there is no point in repairing it. Just install a new relay.
3. Next, check the condition of the fuse that controls the operation of the windshield wiper drive.
4. Disassemble the steering column to allow you to examine the state of the switch. If the insulation is damaged or there is other damage, replace the unit.
5. Unscrew the electric motor from the body and check it in action. If the damage is not serious, it can be repaired. It's better to immediately replace it along with the relay.
6. Check the drive. It is not uncommon for a pulley to break on it, which is why the device has to be replaced with a new one.
7. Make sure the trapezoid is in good condition. It may be necessary to replace the windshield wiper trapezium on a VAZ 2110 if, during operation of the car, the lubrication of the device has deteriorated and all kinds of debris and water have gotten in there. If the lubrication does not work properly, the plastic bushings of the hinges wear out, causing play and increasing resistance during operation of the device. The trapezoid itself serves to transmit force from the electric motor to the windshield wiper arms.

What are the causes of breakdowns?

The most likely factor causing the wipers to stop is the blown working element in the fuse. Eliminating this malfunction involves performing the simplest action - replacing the fuse link. It is located in the corresponding mounting block, located on the left side of the steering column. It will be useful to stock up on a fuse diagram, which will help you easily find the insert we need.

When the purifiers stopped functioning intermittently, the control relay most likely became unusable. This component is also located in the previously designated block. When a relay fails, it is replaced with a new analogue. However, we note that according to numerous reviews from owners of domestic small cars, certain statistics have been formed indicating the small number of cases of breakdowns of this kind.

The most common cause is the destruction of bushings. They are made of plastic, so they do not boast a long service life, which reaches a maximum of three years. The process of destruction of elements is primarily influenced by the quality indicator of the material. Here, the only effective measure is replacement, and to carry it out you should acquire a repair kit, which is available at a specialized retailer. In this case, the trapezoid is replaced.

If the owner of a Lada Kalina discovers that the wiper drive is not working, this indicates that the unit’s motor has failed. In order to verify this fact, you will need to make sure that voltage is supplied to the motor contacts from the on-board network. This procedure is easily performed using a regular tester. If there is power, then we definitely change the motor.

Alternative solutions

Most car owners of the domestic “ten” are accustomed to replacing worn out and faulty windshield wipers with similar ones.

Often this happens because they do not see alternatives and are not familiar with them.

For all VAZ 2110 models, regardless of the year of manufacture, it is possible to install windshield wipers for the driver and passenger sides of the same size - 20 inches. The length of the brush is 508 millimeters.

But this size can be increased to 530 millimeters . It is not recommended to install more, since this way the windshield wiper will not be able to work effectively, and the drive simply will not cope with the load. As a result, too long brushes cause squeaking and jerky work. Plus, don’t count on a long service life of the wiper mechanisms.

The original windshield wipers for the 10 are quite good. But there are more expensive, but also more highly efficient, high-quality devices.

Today it is fashionable to use frameless wipers, especially from Bosch. Their advantages lie in their compactness and a special, reliable leash mechanism.

But as practice shows, on the windshield of the VAZ 2110, as well as other VAZ models, they do not look very nice, because the fasteners on the leash turn out to be massive. Although if you modify them a little, you will get a very good result.

Part of the old and new sample

Selecting a new part for a VAZ-2110 is not such a simple matter. Not everyone knows that there are old and new trapezoids.

The old-style trapezoid rods are secured with two studs.

The new type of rods are installed without problems if you remove one pin.

Therefore, it is better to remove the old part and take it to an auto parts store. They are not only attached differently, but also differ in the connectors through which they are connected to the motor. If you can’t find an old-style trapezoid, and this is exactly what you have, you’ll have to redo the system or look for a used part.

• As a rule, trapezoids of a new type are available for sale from various manufacturers. One of the popular models has the article number VLT2110–5205010-Р.

  If the windshield wiper motor is working properly, you can only change the trapezoid itself.

Which brushes to choose

Standard VAZ-2110 brushes consist of three elements:

• frame;
• the brush itself;
• fastenings

The frame of the device is made of metal and has a composite structure, which includes one main rail and two additional ones located on it. The brush is made of soft rubber. In the middle of its working surface there is a longitudinal protrusion (keel), which, in fact, cleans the glass. The brush is attached to two additional frame slats, fitting into their grooves. To ensure that the wiper slides easily across the glass, some manufacturers coat its working part with graphite.

In the center of the main rail there is a fastening mechanism with which it is attached to the leash. It is a guide into which the hook of the leash hooks and a plastic latch that secures the connection.

Having decided on the size of your wipers, do not rush to buy the first model you come across. The fact is that the auto parts market today is filled with fakes. By skimping on some 100 rubles, you can buy wipers that will work effectively for several days, and after that they will begin to creak and let water through.

Helpful information

Before purchasing a part, you need to find out which trapezoid is needed: there are “old” and “new” samples, indistinguishable in appearance. However, there are quite serious internal differences, which makes it impossible to install the “wrong” trapezoid.

However, our mechanics found an interesting way: a small modification (removing “extra” fastening studs on both sides of the body) solves the problem.

Moreover, experts advise installing a trapeze from Priora on a VAZ 2110 - in this case, a rework is also needed, but some cost savings are achieved (spare parts from Priora are cheaper). The modification consists of replacing the wiper arms ( on the VAZ 2110 they are slightly smaller

).

In addition, the connectors for connecting the electric motor are different. Here you need at least minimal knowledge in electronics, because you will have to install new wiring, reliably insulating it.

Mechanical problems

Often the windshield wiper on a VAZ-2110 may not work due to a loose nut pressing the blade holder. This fault can be repaired in a few seconds. It is enough to tighten a poorly tightened nut to restore the functionality of the wipers. Some events may indicate an unscrewed nut:

1. When the electric motor is running, the brushes do not move.
2. The brushes stop working on their own in an intermediate position.

Also, brush holders may stop due to poor contact pressure in the gearmotor. If the teeth on the gearmotor gear are crumbled, the brushes will also not work.

mechanics Often the wipers on a VAZ 2110 car do not work due to a banal loosening of the nut that presses the brush holder to the trapezoid shaft. You can restore the system's functionality instantly by adjusting the angle of the brush and tightening the lever with a nut.

An unscrewed nut that facilitates the transmission of torque from the gearbox to the trapezoid can be reported by one of two events:

• the electric motor remains operational in all modes, but both brushes do not move;
• the brushes spontaneously stop working in an intermediate position.

However, stopping of the brush holders in an arbitrary position can occur due to poor pressing of the “limit switch” contacts to the gear motor gear or oxidation/burning of the same contacts. And the brushes are not able to move even after chipping the teeth of the gears, which do not have a long service life - after all, they are made of plastic.

Windshield wiper failure can occur for quite trivial reasons:

• fuse F5 burned out;
• the terminals of the connecting blocks are oxidized or burnt;
• wires are faulty;
• relay K5 524.3747 broke;
• ordered the steering column switch to “live for a long time”;
• the nut that attracts the trapezoid crank to the gearbox has become loose;
• the nuts securing the levers to the trapezoid shafts were unscrewed;
• The brushes are frozen to the glass.

Often, wipers on models of the VAZ 2110 family do not work due to complex faults:

• oxidation/burning, insufficient pressing force of the contacts of the limit switch located on the gearbox cover;
• brushes hanging in the gearmotor;
• burnout/contamination of the collector;
• break in the armature winding;
• chipping of gear teeth in the gearbox.

Replacement process

The easiest way to get rid of problems with VAZ-2110 windshield wipers is to contact a service station. There the trapeze will be replaced in an hour or an hour and a half. But if unscrupulous repairmen notice that the owner does not understand the cause of the breakdown at all, they can repair the car for half a day, saying that the problem is very serious.

Therefore, the best option to save money is to replace the part yourself. This process works as follows:

First of all, you will need to dismantle the old trapezoid. To do this, you will have to disassemble and remove the windshield wiper arms. To do this, you will have to unscrew two nuts with a 12mm wrench.

Care must be taken when removing the arms, as the powerful springs create a problem during removal. It is better to bend the leashes first

Disconnect the wiper motor gear pads.

Unscrew the nut of the left trapezoid fastening.

Unscrew the nut on the other side.

Unscrew the fastening of the gearmotor bracket.

Remove the trapezoid from the studs and remove it.

A new spare part must be assembled before installation, since it is in a disassembled state. When connecting parts, you need to make sure that all parts are aligned and adjusted. Only after this are the nuts tightened.

Before installing a new trapezoid, it is advisable to lubricate all its rubbing parts with graphite lubricant. Some advise using lithol, but it loses its properties at sub-zero temperatures.

Repairing a trapezoid using a repair kit

If the bushing in an old part is simply worn out, it is not necessary to change the entire trapezoid. It is enough to simply repair it using a repair kit. As a rule, it has everything you need. To repair the trapezoid, you will also have to remove it. When removing the wiper arms, you must try to act extremely carefully, otherwise you may damage the glass or paint on the edge of the hood.
