The windshield cleaning system in your car should always be in working order. After all, no one knows when to turn on the wipers, and the driver’s safety while driving largely depends on them. We will tell you more about how to change the windshield wiper motor yourself and in what cases it is necessary below.
Technical characteristics of the gearmotor
Shaft rotation frequency at supply voltage 14 V, torque 0.15 kgf.m and ambient temperature 25±10°C, min –1
— first speed 30–40
— second speed 55–70
Current consumed under these conditions, A, no more than:
— at first speed 3.5
— at second speed 5
The purifier has three operating modes, they are activated by the right steering column switch.
Intermittent mode is provided by an electronic relay K2 type 524.3747 installed in the mounting block. This relay also turns on the wiper motor at low speed when the windshield washer is turned on.
The relay must ensure that the electric motor is turned on with a frequency of 14±4 cycles per minute at a gearmotor shaft speed of at least 20 min -1, a temperature of 20±5°C and a supply voltage of 14±0.2 V.
When the cleaner operates at low speed in constant mode, the supply voltage is supplied to diametrically opposed brushes.
When the cleaner operates at maximum speed, “+” power is supplied to the brush located on the side.
To relieve the load on the contacts of the ignition switch, the cleaner is connected through an additional relay K6 in the mounting block.
It is recommended to replace a faulty gearmotor with a new one (cleaning the commutator, limit switch contacts and replacing gears is possible).
Bent levers are straightened.
When the hinges wear out, they are replaced.

How the device works
Despite the simple functionality of the cleaning system, it is necessary to understand how windshield wipers work. Key details you need to know:
- The electromagnetic relay receives the control command and sets the operating mode of the brushes. Depending on the vehicle, the wipers may operate intermittently at short intervals of 3-5 seconds, continuously move at a set speed, or enter wash mode with the washer on.
- The windshield wiper motor receives power from the on-board electrical system. The exact connection diagram depends on the car model.
- The windshield wiper arms, and along with them the glass cleaning brushes, are driven by an electric motor with a worm gear and a lever drive (trapezoid). The trapezoid transmits and converts rotational motion from the electric motor to brushes, which, pressing tightly against the working surface, remove dirt and moisture from the glass.
A properly configured system should not leave streaks or mechanical damage on the surface of the glass, or make noise during operation. In case of such problems, it is necessary to promptly eliminate the malfunction.
How does a trapezoid work?
The windshield wiper trapezoid consists of a system of rods and levers that convert the rotational movement from the gearbox into the reciprocating movement of the leads with brushes. A standard device should perform the following functions:
- movement of the brushes when the windshield wiper motor is running;
- ensuring the required amplitude and speed of cleaning;
- Windshield wiper arms with two or more blades must move synchronously.
Windshield wiper trapezium
The trapezoid, like the electric motor, is an important component of the system. In case of any malfunctions (the appearance of backlashes) in its operation, the efficiency and quality of glass cleaning deteriorates. For greater reliability, the trapezoid elements are made of sheet steel, which is resistant to aggressive environments and also has high bending rigidity.
Depending on the design of glass wipers, trapezoids can be one-, two-, or three-brush, and according to the principle of operation, they can be symmetrical or asymmetrical.
Wiper motor
The windshield wiper motor has a basic design regardless of the car model. The main elements include the electric motor itself and the gearbox (usually a worm gear), which increases the force from the electric motor several times. Modern devices can be equipped with additional elements, including fuses for protection against heavy loads, heating elements for operation at low temperatures, and much more.
Windshield wiper motor for VAZ 2110
The windshield wiper gear motor is the most important element of the system, which ensures its performance. The brushes must fit tightly to the glass and move freely along it, otherwise there will be an increased load on the electric motor.

Today, the next article in the series “Crystal VAZs or typical breakdowns of domestic cars” is dedicated to the “classics”: VAZ-2101, 2103, 2104, 2104, 2105, 2106 and 2107. These cars have been driving along our roads for decades and, despite Despite all the shortcomings that we will talk about, their popularity is still high.
Micromotor gearbox VAZ 2110
The serial micromotor gearbox of the VAZ 2110 has found its application in the heating system of this car. Such a gear motor for the VAZ 2110 stove, a photo of which is presented on the Internet, is responsible for regulating the air temperature created by the heating system to warm up the cabin, engine, windshield and stern glass. There are several modifications of such products that were installed on the same make of car, so you should study the instructions for the heater gear motor 2110, the drawing for it and visually compare the new part with the old, dismantled one for similarity. Only after this should it be installed to replace the failed one.
Photo of heater gearmotor 2110
The main reason for the failure of this part is the lack of air temperature control by the car's electric heater. Checking the functionality of this micromotor gearbox for the VAZ 2110 damper drive consists of the need to supply electricity from the battery ( 12 V ) to its engine in the middle position of the heater. At the same time, the operation of the controller is checked, failure of which will also indicate a lack of air temperature regulation.
Causes of defects in the heater damper gearmotor of the VAZ 2110
If there is no change in air temperature, the following defects are possible:
- The heater damper motor gearbox of the VAZ 2110 has failed
- The integrity of the electrical circuit is broken, i.e. the supplied voltage does not reach the engine
- The presence of a defect in the autonomous control system of the vehicle heating system
If it is necessary to replace the heater damper gearmotor of a VAZ 2110, we carry out a number of the following operations with our own hands:
1. Prepare metalworking tools. We will need Phillips head screwdrivers, both short and long, as well as a 10mm socket or open-end wrench.
2. Free the windshield wiper contacts from the rubber safety caps
3. Using a 10mm wrench, unscrew the contact nuts.
4. We free the frill from the decorative type plugs (there are 4 of them) and access to the screws appears.
5. Remove 2 nuts from the side planes of the frill; for this it is advisable to use a set of keys - heads with a ratchet - wrench.
6. Remove the rubber seal from the electric motor compartment
7. Unscrew the screws that secure the thermal radiators of the electric motor.
8. We dismantle the frill, having first disconnected the pipeline.
9. The location of the damper motor is the left plane of the heater device, not far from the vacuum brake system booster. It is secured with 3 screws.
