Selecting and replacing a windshield wiper motor for 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:

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.

Rear window wiper

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

1. Remove the holder and rear wiper blade;
2. Remove the rear door from the upholstery;
3. Remove the battery negative terminal wire;
4. Disconnect the terminal block from the windshield wiper motor wiring;
5. Loosen the nuts securing it to the door (there are 3 of them) and dismantle the motor;
6. 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:

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 .

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.

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.

Good technical characteristics of the gearmotor

Rotation speed of the gear motor shaft at a supply voltage of 14 V, load torque of 1.47 N•m (0.15 kgf•m) and ambient temperature (25±10) °C, min –1

• first (small): 30–40
• second (large): 55–70

The current consumption at the above load should be no more than:

• at first speed - 3.5 A
• at second speed – 5 A

The device has found its application not only in passenger cars, but also in all other types of vehicles. Even large submarines, helicopters and airplanes are equipped with windshield wipers, which perform an irreplaceable role and at the same time have a very simple operating principle. When the wipers operate, excess water, dirt and other foreign objects on the windshield begin to be removed.

Car models have several operating modes: with a given period of time; constant; single. The auxiliary mechanism supplies water to remove large amounts of dust or dirt from the windshield.

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.

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.

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.

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.

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.

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:

1. The first step is to dismantle the car's dashboard;
2. 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;
