How to remove the wiper motor of a VAZ 2110

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

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.

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.

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.

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;

VAZ 2110 windshield wiper motor - advice from car owners on repair and replacement

How to disassemble and repair the windshield wiper motor of a VAZ 2110

Repair of VAZ 2110 wipers mainly consists of straightening damaged or deformed levers or rods, and if this is not possible, then replacing them with new parts. If the VAZ 2110 windshield wiper motor is in faulty condition, it will have to be replaced with a new one. Regarding repair work, we can say that the VAZ 2110 windshield wiper motor only allows for the replacement of gears, as well as cleaning the contacts of the ring switch and cleaning the commutator.

So, in order to repair the windshield wiper on a VAZ 2110, you must first remove the windshield wiper from the car. To do this, first of all, the nut securing the wire is unscrewed, the wiring is removed from the gearmotor shaft, the three bolts securing the gearbox are unscrewed, then the wiper motor of the VAZ 2110 car is removed from the bracket, and the protective film is removed from it. The next step is to unscrew the two fastening screws and remove the plastic cover. Then the two fastening screws are unscrewed again, after which the panel is removed along with the switch contacts and the gasket is removed. Next you need to pull out the gear, plastic washer and gear motor shaft, then pull out the intermediate gears. To avoid any difficulties in further assembly, the gears should be marked relative to their axes, because they have opposite inclination of the teeth.

Dismantling the device

To complete the procedure successfully, perform a complete dismantling. It is no secret that such a process is quite troublesome and time-consuming. Especially if you have to repair a part from old cars, such as Tavria, KAMAZ, Priora, and so on. In this case, you will have to use several separate steps, including unscrewing the nuts that act as fasteners for the levers.

In the future, you can begin to remove the levers themselves from the tapered splines of the drive. If you have any difficulties at this stage, the splines can be treated with penetrating lubricant. Next, the lever drives are dismantled by unscrewing the nuts, as well as removing the rubber gaskets and plastic bushings.

In the harness, the wiring block is disconnected and pulled out using the raised edge of the seal, through a special slot in the partition of the engine compartment. The next step is to remove the windshield wiper.

Now you will have to unscrew the washer from the removed device and remove the spring retainer. And also you can’t do without disconnecting the rod. As a result, all you have to do is dismantle three bolts and remove the engine. After a full visual inspection, begin replacing any faulty parts.

If this does not give any results, the only way out of the situation will be to buy a new motor. If the problem is resolved, the glass cleaning system must be reassembled in the reverse order.

Replacement features and diagram

True, you must understand that the features of the procedure vary depending on the model of a particular vehicle.

Therefore, before performing a series of any actions, pay attention to the technical features of the system, read the service manual for the car

First of all, you must unscrew the nuts securing the brush arm. The help of a wrench will come in handy here. Then remove them from their installation location. If difficulties arise, use a penetrating lubricant.
Then you need to remove the lever drives by unscrewing the nuts that secure them.
The next step is to disconnect the connector with the wires in the harness and lift one part of the seal through the hole formed.
As a result, all that remains is to dismantle the wiper itself. Then remove the washer and spring mount. After successfully achieving such goals, all that remains is to disconnect the pull rod, unscrew the three screws and remove the motor. Unit repair is characterized by particular simplicity and speed of execution.

Failure of windshield wipers during sudden rain or snowfall is a very unpleasant thing. In this case, until all problems are resolved, you are simply unable to move, since visibility can drop to almost zero. That is why it is better, even in more favorable weather, to make sure in advance that the wipers are working flawlessly.

Replacing the windshield wiper motor and trapezoid

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.

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.

The process of replacing the windshield wiper motor on a VAZ 2110

The procedure for performing work to replace the motor with an imported analogue (from a Volkswagen):

1. It is necessary to disconnect the negative terminal from the battery. 2. Dismantling the windshield wiper (unscrew the nut of the arm and remove it). 3. Unscrew the three gearbox bolts and remove it from the bracket (after marking the position of the brushes on the windshield with a wax pencil). 4. It is necessary to disconnect the electrical connector of the motor (loosen the mounting bolts and remove the motor assembly with rods). 5. Remove it from the space under the fairing. 6. Disconnect the motor from the assembly rods (it is necessary to loosen the 3 mounting screws). 7. To connect a new motor, you will have to redo the connection chip itself (there is nothing complicated, and it costs a penny). 8. On the VAZ 2110 trapezoids, the hole for the gear motor shaft is slightly larger than the required diameter, so the lever will have to be replaced. It is necessary to supply a new sample, it fits perfectly. An important point when installing a new gearmotor on a trapezoid is that you do not need to place an engraver under the bolts. Otherwise, the “crank” will catch the bolts. 9. When replacing the windshield wiper motor of a VAZ 2110, it is advisable to use new wires to avoid accidental short circuits. As a last resort, if you use twists, be sure to properly insulate all connections from moisture.

Assembly is carried out in reverse order. After assembly, a test drive of the innovation is required. The result is obvious; replacing the windshield wiper motor on the VAZ 2110 speeded up the work of the wipers significantly, even on dry glass.

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.

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.

Features of the electric motor design

The windshield wiper base consists of several individual elements. Among them are the following:

lever axis;
electric motor (device that drives the windshield wiper);
brush lever;
brushes;
brush holder;
mounting block;
frame;
gearmotor.

Regardless of the model and manufacturer, such parts are irreplaceable. Variations are explained only by model characteristics. For example, the latest innovations in the automotive industry include upgraded versions with a wide variety of functions.

Some of them have a heating function, some work automatically, reacting to any contact with water or dirt on the windshield. In general, these are all the existing parts of the device, so the next step in learning how it works is to review the basic concepts.

It is no secret that all glass cleaners are very fragile and vulnerable devices that require extensive care and can break. Such a structural element is forced to cope with all the work of cleaning the windshield, therefore, with prolonged use, a problem such as rapid wear is noticed.

The trouble is associated with constant contact of the rubber brush with the surface of the glass and heavy loads. As a result, a good model should have impressive flexibility and rigidity.

How to check the windshield wiper motor? When checking the wiper motor for serviceability, it is enough to pay attention to a number of key subtleties and predetermining factors. One of them is weather conditions.

It is no secret that prolonged exposure to low temperatures, heat and rain do not have the best effect on the condition and operation of parts.

Checking the windshield wiper motor is not difficult at all. If there are any defects, scratches or streaks will be visible on the windshield. It is also possible that incorrect noise may occur from the operation of the brushes. In addition, the brushes can move very slowly, out of step, or very quickly.

In this case, you should pay attention to the motor

When inspecting, consider the condition of the relay or lever. If one of the important elements fails, this will be accompanied by movement of the brushes in different directions. If the windshield wiper blades begin to fly off during active operation, you will have to use a new wiper blade holder.

Principle of operation

Modern cars and many other vehicles may be equipped with two windshield wipers. A similar solution has a double design for the front glass.

It does not include rubber bands located on the blade, which provide more efficient and productive work, as well as for the rear window (here we are talking about a single version).

Most existing models are capable of operating in three different modes:

Slow mode.
Intermittent operation.
Fast work.

At the heart of each glass cleaner is a corresponding motor, which is equipped with a gearbox, brushes, a lever system and an automated mechanism that allows you to return the wipers to their original position.

In addition, together with the device there is a device for supplying water to the entire area of the windshield. If it fails, the motorist should seriously think about upcoming repairs.

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:

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

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.
