Replacing the windshield wiper motor of a VAZ 2110

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:

Remove the windshield trim (jabot)
Remove the insulation and seal under the hood
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.

Rear window wiper

The rear electric motor can also be removed and a new one installed. To do this you need:

Remove the holder and rear wiper blade;
Remove the rear door from the upholstery;
Remove the battery negative terminal wire;
Disconnect the terminal block from the windshield wiper motor wiring;
Loosen the nuts securing it to the door (there are 3 of them) and dismantle the motor;
Install a new electric motor. Replacement is in reverse order.

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:

The windshield wiper motor uses the finger, which drives the trapezoid itself.
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 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:

Windshield wipers begin to do their immediate job poorly. This occurs due to the weakening of pressure.
An unusual noise is heard during operation.
A backlash appears, which can be determined even visually, since the glass will be difficult to clean.
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.

Purpose

The windshield wiper gear motor is designed to drive the lever system of the glass cleaning mechanism. It is installed under the windshield in a niche and is connected by a shaft to the windshield wiper arms. It has three operating modes and is controlled by the right steering column switch. In the first position of the switch, the intermittent operation of the wipers is activated. In this case, control is carried out through an electronic relay installed in the mounting block. The same relay also controls low speed in constant mode.

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.

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

Review

Many dozens of car owners agree that the windshield wiper motor of the VAZ 2110 is quite frail - both in old and new modifications. Moreover, its operation depends on many parameters: the condition of the wiper rubber bands, wind, the amount of water pouring onto the glass, the voltage supplied to the wiper motor. Usually there are more complaints about the front window wiper, but the rear window on models 2111 and 2112 also has exactly the same gear motor.

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.

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.

Without wipers, it is almost impossible to overcome rain or snow, as visibility is reduced to a minimum. This is why it is important to keep your windshield wipers (the official name for windshield wipers) intact. This material describes the scheme by which the wipers work in a VAZ 2110 car, the main malfunctions, as well as windshield wiper repair.

Device and possible malfunctions

To understand the operation of the wipers, you will need an electrical diagram, which is present in the VAZ 2110 operation and maintenance manual. You also need to know what the unit consists of:

The trapezoid is the main part through which the motor transmits movement; the trapezoid most often wears out, and as a result, repairs are needed.
Electric motor - due to this unit, the wipers move; the motor can burn out, which will cause the failure of the entire unit.
Pump - this element is needed to pump cleaning fluid into the wipers. If the pump breaks, then you can forget about keeping the front window clean, although the wipers will still run across the window.
Tank - everything is obvious here, it stores window cleaning fluid.
Windshield wiper – mounted on a trapezoid, performs a cleaning function. First of all, you need to pay attention to the size of the windshield wiper.

Repair and replacement are required when the motor is damaged, since it cannot be repaired. The trapezius also very often fails, but sometimes it can be restored. The assembly diagram is quite simple, so the owner of a VAZ 2110 will quickly discover the reason for the malfunction of the assembly.

Geared motor from Volkswagen Transporter

Volkswagen's electric motor requires a little modification, but those who go this route are usually satisfied with the continued performance of the wipers and the stability of the windshield wiper.

This replacement requires minor modifications. In the 2005 “dozen”, the electric motor is connected to the trapezoid using a lever that has a large hole. Therefore, it is enough to change the lever (take a new sample), and everything will fit perfectly.

And one more point: when installing the motor on a trapezoid, you cannot place the engravers together with the bolts so that the crank does not touch them during operation.

Repair

To repair this unit, you need a minimum of tools:

Set of keys and sockets.
Screwdriver Set.
WD-40.
Rags.
Replacement parts.

It is quite easy to determine which parts are not working. For example, if the wipers do not move, then the motor has failed. If the trapezoid moves, but the glass remains dirty, then the pump or tank is damaged. The size will help you understand what condition the part is in - if the size has decreased too much, then the element needs to be changed. In any case, you need to make sure of the speculations; for this you should analyze:

The first step is to dismantle the car's dashboard;
Next you need to find the relay related to this mechanism. It is screwed to the body of the VAZ 2110. If the electrical elements do not work, then the relay needs to be changed; repairs will not help;
