Replacement and repair of trapezium wipers VAZ 2110, 2111, 2112

Replacing the windshield wiper motor and trapezoid

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:

• screwdriver flat and Phillips

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

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.

Photo report on the removal and installation of the windshield wiper trapezoid on a VAZ 2110-2112

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.

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.

After this, the plastic part is removed

To do this, the screws are unscrewed.

The next stage includes removing the plugs and other fasteners.

You can reach the trapezoid only after removing the plastic parts of the casing. The trapezoid is attached to the motor. It will also have to be dismantled.

The trapezoid, together with the motor, is attached to the body using a bracket. You need to disconnect them.

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.

Plastic bushing repair

If you can’t find a repair kit specifically for your model, don’t despair.

The main thing is to cool the drill frequently, otherwise the plastic may become deformed. If the sleeve does not fit in outer diameter or length, it can be sharpened with a file. The old trapezoid is disassembled, after which it is necessary to install new elements to replace the worn ones.

Before installing the frill, we check the operation of the new trapezoid.

Using a repair kit will reduce costs, but increase labor costs. Therefore, every VAZ-2110 car owner chooses the best option for himself. Replacing a trapezium yourself can be done alone in 2–3 hours, the main thing is not to damage the plastic elements.

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 .

Device design

The design of the windshield washer on the VAZ 2101 consists of a gearmotor powered by an incoming current that drives the washers, a switch, a switch, a relay for switching on the intermittent mode, an additional relay, etc.

Glass cleaner device

The node consists of:

1. Windshield wiper trapezoids: with its help, the motor transmits movement. It wears out quickly, so sometimes repairs to the trapezoid are necessary.
2. An electric motor drives the wipers of the VAZ 2110. If the motor burns out, the entire unit will fail.
3. The windshield wiper pump pumps cleaning fluid. If the electric pump breaks down, then, despite the operation of the wipers, the windshield will not be cleaned.
4. The purpose of the tank is obvious - window cleaning liquid is poured into it.

Thanks to the electric motor, the wipers on the VAZ 2110 can operate in three modes:

1. Intermittent. The switch lever is in positions II and III.
2. Constant - with a low speed of movement of the brushes. The switch lever is in position IV.
3. Constant - with fast movement of the wipers. In this case, the shift lever is in position V.

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.

Replacement procedure

So, you have chosen a gear motor for your VAZ - one of the first three. Let's look at how it is replaced. When performing this work, there is no need to disassemble the entire windshield wiper system. We proceed like this:

1. Disconnect the negative terminal from the battery;
2. Having noted the position of the brushes on the windshield, unscrew and remove the levers;
3. Remove the cover from the fairing;
4. Unscrew the nut securing the crank mechanism bracket to the motor axis;
5. Unscrew and remove the bracket itself. It is secured to the body with 3 bolts;
6. We remove the non-working or poorly functioning motor from the studs;
7. Replacing the old one with a new one is done in the reverse way.

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.

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.

Replacing the trapezium wipers of a VAZ 2110

I don’t think anyone will argue with the fact that good visibility is necessary to drive safely. To do this, it is necessary that the mechanism driving the brushes works, the trapezoid of the wipers is in good working order, but the brushes themselves must be in good condition and appropriate for the time of year.

Bad weather reminds us to regularly replace our windshield wiper blades. Some manufacturers of these extremely important parts recommend changing brushes once a year. The fact is that under the influence of the environment, rubber inserts gradually dry out and lose their elasticity. Hard rubber works like a scraper, leaving streaks and streaks on the glass. Run your finger along the blade of the eraser; if it is worn out and dull, you need to replace the brushes. Don’t skimp on small things and replace dry or worn wipers before the slushy season sets in.

Replenish the washer fluid supply in the washer barrel in a timely manner. To avoid poisoning from toxic pores, buy only proven glass cleaning liquid.

What to do if the wipers stop working due to electromechanics

If the wipers on a VAZ 2110 do not work, the problem may lie in failed gearmotor elements.

The following elements of the electric motor can fail:

• Limit switch;
• Motor anchor (it could burn out);
• Contacts (oxidized);
• Springs on motor brushes;
• Gears in the gearbox (worn out);
• Collector (burnt or dirty).

Repairing wipers on a VAZ 2110, if the cause is correctly identified, will not be difficult.

To do this you need to do the following:

• Remove the dashboard;
• The relay is screwed to the left of the car body; if it is faulty, replace it;
• Check the fuse;
• We disassemble the steering column and study the switch. If the insulation is damaged or other problems are present, change the steering column switch;
• We take out the electric motor and, if the damage is minor, we carry out repairs. If it requires replacement, feel free to replace it along with the relay.

The wipers on the VAZ 2110 may not work due to mechanical faults.

Quite simple things can prevent the wipers from working properly. For example, such as loosening the nut that secures the electric motor and brush holder. Or weakening the springs of the leashes. The cause may also be the destruction of gears, which is associated with the fragility of the material. As a rule, they are made of plastic.

As a result, we can say that the reasons for the breakdown of wipers are quite simple.

Among the “frivolous” breakdowns, the following can be distinguished:

• The fuse in the mounting block died;
• The wires are worn out;
• The gears are worn out;
• The connecting terminals have loosened;
• Contacts have oxidized;
• The mechanism is dirty.

Such breakdowns are not difficult to repair, and they will not cause significant costs when replacing parts.

Approximate prices for parts:

• Relays - from 285 rubles;
• Geared motor - from 1650 to 2200 rubles;
• Windshield wiper trapezoid - from 1,700 rubles;
• Assembled windshield wiper - from 3050 rubles;
• Windshield wiper lever (left) - from 435 rubles;
• Windshield wiper lever (right) - from 330 rubles;
• Brushes from 165 rubles per piece.

All these reasons why the wipers on the VAZ 2110 do not work can be eliminated quickly enough, without extra effort and expense. Of course, the car will let you down if something serious breaks down. For example, combustion of an electric motor, oxidation of contacts that now need to be replaced

It is very important to take care of your car. You need to check the condition of elements such as wipers at least once every couple of days or before getting into the car.

It will be very sad if you notice that your wipers break down during a rainstorm on the highway. Remember: if the brushes freeze to the glass, the electric motor will burn out, then you will have to replace it. Therefore, in winter, be sure to move the blades away from the windshield if you leave your car.

Types of wipers

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.

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... .

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.

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.

Main malfunctions of the mechanism and ways to eliminate them

When is windshield wiper motor repair required?

Before removing, checking the motor and replacing it, familiarize yourself with the main faults of the unit:

1. The device does not function, the safety element does not work either, but its integrity does not work. In this case, you must first diagnose the integrity of the wiring and contact connections, and if damage is detected during the diagnosis, they must be eliminated. If everything is fine with the wiring, then you need to check the steering column brush switch; it is quite possible that it has failed. Naturally, the problem may also lie in the electric motor, for example, its contacts are burnt or the brushes are acidified; if this is the case, then it will need to be repaired or replaced. It would not be superfluous to diagnose the wiring that goes to it and the block. It is recommended to clean the safety element or replace it if cleaning does not produce results. If after performing all these steps the system still does not work, then you will need to diagnose the integrity of the winding of the so-called motor armature. If the diagnostics show that the circuit is missing, then either the armature or the entire electric motor assembly is replaced.
2. The brushes do not work, while the safety element is working, and the fuse in the power circuit regularly fails. In this case, the levers are diagnosed - perhaps they cannot work as a result of deformation or freezing of the brushes to the windshield. It is much worse if the failure of the unit is caused by a short circuit in the armature circuit, then you will have to decide what to change specifically - the armature or the gear unit.
3. The device does not operate in intermittent mode. As a rule, such a malfunction is caused by a failure of a relay or switch. In both cases, it is better to replace the failed mechanism.
4. The wipers operate intermittently but do not stop. In this case, the problem, as a rule, lies in the inoperability of the relay or limit switch. If the reason is the switch, then most likely the spring plastic is not pressed to the end by the gear, and in this case it will just need to be bent (the author of the video is Igor Ivanov).

If the wipers stop turning on

When the VAZ 2107 windshield wiper stops working in both positions of the mode switch, you should start looking for the fault with the wiper fuse. It is installed in the electrical network to protect it from overloads that occur during malfunctions, short circuits or increased load on the wiper motor. If the fuse is working, you should check its contacts. Often they are highly oxidized and prevent the passage of current. Cleaning the contacts is simple - you need to remove the fuse and clean the contacts with a knife, screwdriver or sandpaper. Usually these actions are enough, but sometimes the reason lies in a malfunction of the relay, switch or motor. But more on that below.

If the wipers do not work intermittently

This problem is associated exclusively with a malfunction of the VAZ 2107 wiper relay. The cyclic operation of the wipers is ensured by closing/opening the relay contacts and, accordingly, the power supply circuit of the wiper motor.

The test should begin by monitoring the power supply to the relay block. This is done like this:

• remove the relay;
• turn the wiper switch to the intermittent position;
• Use a control indicator to check the presence of voltage at the terminal.

If there is no voltage, it is necessary to replace the switch or repair the open circuit. If voltage is supplied but the relay does not work, the latter must be replaced. The design of the relay does not provide for the possibility of repair.

If the wipers do not stop at the lowest point

Sometimes when you turn off the wipers, the brushes stop not at the lowest point of the trajectory, but in another arbitrary place. The problem lies not in the VAZ 2107 wiper relay, but in the drive gearbox. It contains a limit switch actuated by a cam. The operation of the cam controls the position of the brushes after turning off the power on the switch lever. Gearbox failure most often occurs in winter, when the driver turns on the wipers that are frozen to the windshield.

To replace the gearbox, you must dismantle it along with the engine and install a new one.

This is interesting: Where is the cabin filter located and when does it need to be changed?

If power is supplied but the engine does not run

There are several reasons why the engine may not work when power is applied. The most common are shearing or wear of brushes or failure of windings. The brushes can wear out over time, or they can freeze to the contacts and break when the VAZ 2107 wiper relay is turned on and power is supplied to the engine. The winding most often burns out when the motor is overloaded. To check, repair and replace the gearbox with the windshield wiper motor, it is necessary to remove the unit from the vehicle.

Trapezium wipers - replacement for VAZ 2110

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.

What affects the condition of the trapezius

The wiper motor and trapezoid are located directly under the glass, so some of the water or washer fluid falls on them. In addition to water, dust, dirt and various small debris get there. All this leads to a change in the properties of the lubricant and deterioration in the performance of the trapezoid. When the lubricant loses its properties, the plastic bushings of the hinges begin to wear out, resulting in backlash and increasing resistance during operation.

How to remove the windshield wiper trapezoid

To remove the trapezoid you will need:

• key to 10;
• thin flat screwdriver;
• crosshead screwdriver.

First of all, you need to remove the wipers. To do this, you need to remove the plastic pads and unscrew the nuts with which they are attached to the trapezoid studs. Then unscrew the screws and side fastenings of the protective casing (jabot) and remove it. If the fasteners do not come out, treat with WD-40. Before removing the casing, make sure to remove all screws, bolts and nuts. If the cover does not come off, look for a fastener that you did not remove. Lifting the frill, disconnect the washer fluid supply tube from the tee, and then move the casing to the side.

Remove the belt that supports the radiator tank and move the tank to the side. Then pull out the partition (sound insulation), which is located behind the tank. Don't forget to remove the washer fluid supply tube from it. Disconnect the electric motor power connectors. After this, unscrew the bolts securing the trapezoid and electric motor. To remove the trapezoid, you must either struggle for a long time, coming up with various options, or place a thin flat-head screwdriver under the far end (relative to the motor) of the lower rod of the trapezoid and pull out the entire structure as if on a slide. You can also turn the left edge of the trapezoid clockwise and pull it out, then remove the engine.

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.

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.

Trapezoid repair

During repairs, it is necessary to clean all elements of the trapezoid from dirt and inspect the studs. If wear is detected on their ribs, the trapezoid will have to be replaced. Repairing a trapezoid involves replacing the plastic caps. To do this you will need a repair kit and boiling water. First, disassemble the trapezoid using a pry bar or a heavy-duty flathead screwdriver as leverage. After this, cut off the old plastic caps. If you can’t cut it, use side cutters and bite off the caps piece by piece until you can pull them out of the trapezoid rods. You can also hold the ends of the trapezoid in boiling water, 2 to 3 minutes is enough, then push the caps out of their seats.

Three types of trapezoids were installed on cars of the “tenth” family - VAZ 2110, 2111 and 2112, which differed in minor details. Therefore, there is a possibility that either the trapezoid rods or the caps will have to be adjusted. Remove the cap and inspect it. If there is a fixing protrusion on top of it, check the recess for it on the rod seat. If there is no notch, you will have to either cut off the protrusion on the cap (does not affect the performance and reliability of the trapezoid) or saw through it in the draft. If there is no protrusion on the cap, no adjustment will be necessary.

Clean the rod and seat, then lower the cap into boiling water for 10 - 15 seconds. After this, it will soften and easily fall into place. Do not install a cold cap as this will destroy it. After the cap has cooled completely (20 minutes), the rod is ready for assembly. Before assembly, lubricate the bushings with graphite grease.

Check the serviceability of the electric motor. To do this, disconnect it from the trapezoid (you need to unscrew the fastening nut) and connect it to the car battery. When working, it should make a low buzzing sound. If you don't know how to connect the motor to the battery, then connect it to the power connector. Turn on various operating modes of the electric motor for 10 - 15 minutes. After that, feel it. If the motor gets hot, it needs to be replaced. An electrical technician can try to repair this device, but regular drivers and car enthusiasts need to replace it.

Causes of malfunction

The weak point of this motor is that there are a fairly large number of contacts along the power circuit. This affects both the voltage and the possible causes of malfunctions: the contact on one link of the chain is lost or unstable, and stable operation of the windshield wiper is no longer possible. In this case, it is quite possible that the motor is not at fault. Therefore, before you decide that it needs to be replaced, check the contacts along the entire circuit.

Fuse

Pay attention to the fuse, it may also be faulty; Performance. Next, you should check the switch itself for serviceability; Operating Parameters

Using an ohmmeter, check the resistance in the circuit breaker between the terminals. If it shows “zero”, you need to change the breaker; Correct connection. Without turning on the wiper, measure the resistance between the fourth terminal and ground. It must also be zero. Otherwise, you need to properly restore the grounding; Voltage. Turn the windshield wiper to low speed and check the voltage at terminal five. It is equal to the battery voltage, but the gearmotor does not work? It needs to be changed.

Causes of malfunction of the VAZ 2110 windshield wiper motor

Putting the trapeze in place

Usually, installing the trapezoid into place does not cause difficulties. Insert it and secure with bolts. Do not overtighten the motor mounting bolt; the motor may need to be turned slightly to get the trapezoid to operate smoothly. After making sure that the trapezoid is working properly, tighten the electric motor mounting bolt, install and secure the sound insulation, frill (do not forget to connect the washer tube), and the expansion tank. Insert the plastic plugs and install them in place, install the arms with brushes and check the operation of the wipers in all modes.

Which brushes to choose

Standard VAZ-2110 brushes consist of three elements:

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.
