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.

What is a windshield wiper trapezoid and what is it for?

The trapezoids are around here somewhere!

The wiper trapezium is a special unit that converts the engine impulse into forward movements of the windshield wipers.

Simply put, it is she who is responsible for their movement along the windshield or rear window of the car. Since weather conditions are often unpredictable, and the windshield must provide complete visibility, failure of this part must be quickly identified and corrected.

Principle of operation

Most often, plastic bushings wear out in trapezoids.

Although, at first glance, it seems that the movement of the brushes occurs directly, in fact, a trapezoid, which is an electromechanical unit, is responsible for it. It works on the following principle:

1. The windshield wiper motor uses the finger, which drives the trapezoid itself.
2. Due to the connection of the gearbox and shafts, oscillatory movements occur, causing the brushes to move along the glass, cleaning it.

It often happens that the trapezoid fails. This happens especially often after or during the winter season. Some inexperienced VAZ-2110 owners turn on the “brushes” without bothering to clear the snow from the glass . Often the wipers freeze to the glass, and an attempt to move them ends in breakage. To prevent this from happening, you should always check the brushes before turning them on in winter for freezing .

How to remove

First of all, it is necessary to de-energize the system. To do this, simply disconnect the negative terminal on the battery.

• set the wiper arms to a vertical position;
• unscrew the nuts and remove them from the rollers;
• remove protective caps;
• twist the nuts (one on each side) securing the brackets at the top;
• dismantle the rubber sealing washers;
• in the engine compartment, remove the wiring harness from the connector;
• unscrew the bolts holding the lower part of the bracket;
• the mechanism rollers are removed from the holes;
• unscrew the nut securing the windshield wiper crank and remove it;
• dismantle the bolts holding the wiper gearbox and the motor in place;
• disconnect the wires from the bimetallic fuse and remove the engine from the bracket.

All that remains is to remove the locking ring and adjusting washers from the gear shaft and install a new motor.
Assembly is carried out in reverse order. To make it more convenient to work, we recommend moving the stove fan slightly to the right. Without this, it will not be possible to remove the windshield wiper. You will also need to remove the fuse box cover and all the relays located there.

The windshield wiper itself must also be moved slightly to the left before removal.

It is better to number the adjusting washers so that they are not confused during assembly.

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.

The design of the windshield wiper on the VAZ tenth model

What components does the electrical circuit of a windshield wiper consist of, what are the dimensions and length of the blades, how do you modify the drive mechanism yourself?

First, let's look at what elements are included in the circuit:

1. Motor or gear motor. An electric motor moves the wiper blades across the glass. If the motor fails, the wipers will not be able to operate.
2. Trapezium wipers. By means of a trapezoid, force is transmitted from the electric motor to the wipers themselves, which facilitates their movement.
3. Expansion tank with liquid. The reservoir is used to store water or a special liquid for washing glass.
4. Windshield washer pump. Using a pumping device, liquid from the expansion tank is supplied directly to the windshield. If the pump breaks down, the wipers will continue to work, but liquid supply will be impossible.
5. Hoses through which water flows from the expansion tank to the glass.
6. Hood mounted injectors. The nozzles function as a liquid diffuser, thanks to them 2 or more jets of water are formed. Depending on the design, one nozzle may be capable of distributing the flow of water into 3-4 jets.
7. And the windshield wiper blades themselves, connected to the trapezoid by means of leads.

In accordance with the operating diagram of the electric motor, the wiper blades can operate in several modes:

1. Intermittent mode, in this case the switch control is in positions 2 and 3.
2. Constant. When activated, the speed of movement of the wipers will be average. The switch is set to position 4.
3. Fast constant, characterized by the rapid movement of brushes across the glass. Using this mode is important when driving in heavy rain and bad weather. The regulator is set to position 6.

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.

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.

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 that will 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. When removing the levers, you need to be careful, since powerful springs create a problem when removing them. 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.

Only after this can the trapezoid be removed. The main thing is not to forget to disconnect all electrical connectors.

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.

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.

Diagram of the front and rear wiper VAZ-2110, 2111, 2112

Wiring diagram for the rear window cleaner and washer:

1 – washer motor; 2 – mounting block; 3 – ignition switch; 4 – rear window cleaner and washer switch; 5 – rear window wiper gear motor; K6 – additional relay; A – to power supplies; B – the order of conditional numbering of plugs in the gear motor block

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.

Finding Electrical Problems

Each owner of a VAZ-2110 involuntarily paid attention to the clicks coming from the left side and the barely audible noise from the gearmotor when the windshield wiper was running. Therefore, at the initial stage of searching for the reasons why the VAZ-2110 wipers do not work, you need to check the performance of this particular product.

If the electric motor does not show any signs of life, you need to check the fuse located on the mounting block, which is located on the left side, under the headlight switch lever. If the fuse is in working order, this indicates a malfunction in the electric drive feeding system.

A multimeter will help determine the problem area in the circuit. You need to check the circuit from the fuse to the gearmotor, from it to the hydraulic corrector.

Naturally, it is necessary to check the fuse itself. If zero is constantly lit on the multimeter screen and a not very pleasant sound signal is heard, then the circuit is working properly. When several numbers appear on the screen, without sound, we move on - we move on to inspecting the terminals and wires.

You can troubleshoot the problem as follows:

1. Clean and tighten all terminals that were checked with a multimeter.
2. Replace wiring.
3. Install a new lever on the steering column that turns on the windshield wiper.

Relay K2 (5243747), located in the mounting block, is responsible for the operation of the windshield wiper. If an intermittent mode is not observed during system operation, then it is time to change the relay. Under these circumstances, the hydraulic corrector also needs to be checked. If the windshield wiper relay has a defect, it will work wonderfully in the third extreme position of the right steering column stalk. A faulty relay does not stop working in all cases. Windshield wipers can function perfectly if they are turned on in position 1, but the fact that there is a defect and the relay is not working correctly will be indicated by pauses between sweeps of the blades. Often the relay simply goes away, and the wipers and heater do not work at the same time. In this case, you usually need to tighten the contacts.

In searching for the reasons why the wipers on the VAZ 2110 stopped working, you also need to check the limit switch located on the cover of the gear motor. It is also advisable to clean the contacts from oxide and bend the contact petals.

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.

Mechanical part

It includes:

• The brushes themselves - their working part is made of rubber and is subject to fairly rapid wear;
• A trapezoid is a structure made of metal guides; they ensure the conversion of the rotation of the electric motor into the actual operation of the wipers. The trapezoid is subject to deformation and clogging of the joints.

Accordingly, from the structure of the windshield wiper assembly, it follows that all breakdowns belong to two groups:

1. Mechanical;
2. Electrical.

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.

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.

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.

• How to repair a windshield wiper trapezoid

Today, no one can be surprised by the presence of a family’s own car. Manufacturers are trying to make their “product” as safe as possible, and this applies not only to the engine and the components that provide movement. The issue of safety sometimes directly depends on the cleanliness of the glass. If the windshield and rear windows are not clean enough, or are covered with drops of water or snow, then you will strain your eyes more and more to fully see the situation on the road. After an hour of driving like this, your concentration will decrease, and this threatens an accident. How can you make sure nothing bad happens? The correct answer is to monitor the condition of the windshield wipers, in particular the trapezoid. This is what we will talk about.

Useful information about the windshield wiper trapezoid

The most important element of the windshield wiper system is the trapezoid. It is this element that is responsible for converting the rotational movement from the electric drive shaft into the translational movement of the wipers. If the trapeze works correctly, then the safety of your movement in bad weather conditions will be ensured. The design of the windshield wiper is quite simple, but reliable and wear-resistant. The main elements of the system are:

- brush and leash;

The design of the trapezoidal wipers on cars from different manufacturers is almost the same. The difference can only be in the dimensions and shape of its various parts. The main elements that create this node are:

Using calculations, designers determine what the profile of the trapezoid links should be. Thanks to this, the structure forms the necessary safety margin, that is, the integrity of the system is maintained when the brushes move. In order to minimize losses due to friction, and to optimize the energy consumption of the electric drive, the trapezoid connecting elements are made of a material based on polyformaldehyde. It produces an extremely low coefficient of friction and is characterized by a high level of wear resistance. To protect metal elements from corrosion, they are coated with a galvanic layer.

When is it necessary to replace the windshield wiper trapezoid?

The incorrect operation of the windshield wiper trapezium, as well as the presence of damage on it, is indicated by malfunctions in the operation of the wipers themselves. For example, they may move too slowly regardless of the operating mode, or stop spontaneously while cleaning the windshield and rear windows. Another clear indication that the wipers are faulty is intermittent movements of the brushes, jumps, and a characteristic sound from the wiper during operation. The main reason for such malfunctions is the presence of oxide on the driver drives in the trapezoid bushings.

It is the oxide that prevents the wipers from rotating normally. If this problem is ignored, then the electric motor, which is subject to a significant load, may also break down, and this entails the possibility of the electric motor’s armature burning out. If there is play in the windshield wiper arms, that is, the arm hits the hood, then rest assured that the trapezoid bushings have worn out.

If you notice even a hint that the windshield wipers are not working correctly, then diagnose the system as soon as possible, and, if necessary, repair or replace the broken unit.

Otherwise, the risk of getting into an accident on the road increases greatly. The need to pay attention to the windshield wiper trapezoid may be indicated by low pressure in the system. If the wipers do not completely remove snow or water, then there is a problem with the pressure.

In order to understand what exactly needs to be done with the trapezoid - change or repair - it is necessary to carry out diagnostics. If you decide to replace the trapezoid, then the new mechanism must be selected correctly. Two trapezoids from different manufacturers can be very similar in appearance, but attached in different ways. The sizes of the leads and the types of connectors for connecting to the electric motor can be different. The conclusion from all this is simple - buy a trapeze from the original manufacturer specifically for your car model.

Wiper design

The main parts of the windshield wiper are the supporting frame and the cleaning element.

Wipers with metal frame

The supporting frame is made of metal or plastic. Wipers with a metal frame are more durable and strong. This frame is used to make winter windshield wiper blades.

Wipers with plastic frame

There is another type of brush design - frameless brushes. The frame in such brushes is a cleaning rubber band and the wiper itself is made entirely of rubber.

Frameless wipers

The cleaning element is made of soft rubber or silicone, which ensures a tight fit to the windshield and excellent cleansing of moisture.

Types of wipers

Classic.

The design consists of seven metal “rocker arms” arranged pyramidally. The largest arc holds two smaller ones, which, in turn, hold even smaller ones and are attached to a rubber blade. This design allows the downforce of the wiper to be evenly distributed. Slowly going out of fashion, these wipers are falling in price every day, while performing their functionality very well in the warm season. The main enemy of such a wiper is snow. But it is impossible to say that these brushes are worse in functionality than frameless ones. The pressing effect of such a design loses its properties over time. Therefore, it is better to change the brush frame itself after a few years.

Frameless.

The “rocker arm” system for this type of wiper is replaced by a thin metal plate that passes through the entire length of the brush. It is a frame, despite the so-called frameless classification. They tolerate snow better, but this design has a disadvantage - the distribution of downforce here is worse than that of “rocker arms”. In the cold there is a shrinking effect. The advantages of these brushes over the previous ones can be called design. Although the taste and color as they say... .

Winter brushes.

They repeat the classic summer design, but all its moving parts are hidden under a rubber cover. But these brushes are not very suitable for summer, since the casing causes too much windage. If the speed is above 90 km. at an hour, the brushes begin to move away from the glass. As good as such brushes are in winter precipitation, they are just as bad in summer precipitation.

Hybrid.

These brushes are the latest development for today. Metal “rocker arms” here replace three plastic arcs, they also act as a winter cover, thereby allowing these wipers to be called hybrid. Another distinctive feature of these wipers is improved aerodynamics. Headwind increases downforce. Although in such a design there is something to freeze on.

In conclusion, we can say that in winter it is better to use winter wipers, and for summer any wipers except winter ones are suitable. It's up to you to choose

In any case, new wipers, no matter what design, are better than those that do not perform their functions at all
