The car is equipped with a windshield wiper 60.5205 or 70.5205 with an electric drive for two blades

The electric windshield wiper motor with a gearbox and a system of drive levers is located in the engine compartment under the lower front end lining

The windshield wiper is controlled by the right steering column switch 3302.3709200 or 9902.3709.

When the windshield wiper is turned off, its blades are automatically laid along the lower lining of the front end.

Windshield wiper malfunctions and solutions

- Cause of malfunction

Remedy

The windshield wiper does not work:

- The electric motor is faulty (clicking noises are heard periodically when the thermal fuse of the windshield wiper is turned off)

Check the electric motor separately.

Disassemble the faulty electric motor.

Clean the commutator, replace the brushes if necessary, lubricate the bearings with engine oil.

If the winding in the electric motor is burned out, replace the electric motor

- Switch is faulty

Check with a test lamp, replace if necessary

- Short circuit in circuits

Connect a test lamp instead of the fuse and, disconnecting sections of the circuit, starting from the windshield wiper, find the short circuit and repair it

- Sticking of the axes of the levers or hinges of the lever system (clicks are periodically heard when the thermal fuse of the windshield wiper is turned off)

With the windshield wiper removed, remove the crank from the gearbox axle and check the lever system by hand for any jams.

Lubricate all joints and axles with engine oil

- Wear of the worm gear of the gearbox (the operation of the electric motor can be heard, but the brushes do not move)

Replace the worm gear

- Windshield wiper thermal fuse is faulty

Check with a test lamp, replace the fuse if necessary

The motor armature rotates at low frequency:

- Contamination or oxidation of the collector

Disassemble the electric motor, clean the collector

- Armature jamming in bearings

Clean the shaft journals

- Faults in the windings (see “The windshield wiper does not work”)

Check the windings, replace the motor if necessary

The electric motor is running, but the brushes are motionless:

- Weak fastening of the crank on the axis of the gearbox

Check the crank fastening. Tighten the fastening nut

- Broken gear teeth

Replace the gearbox

During windshield wiper operation, the blades hit body parts or the blades stop too high after switching off:

- Brush arms are installed incorrectly

Change the setting of the brush arms

The windshield wiper operates at one speed:

- Switch is faulty

Check with a test lamp, replace if necessary

- Brushes stuck in the electric motor

Disassemble the electric motor, check the condition of the brushes, replace the electric motor if necessary

Assemble and install the purifier in reverse order.

In this case, we place the crank on the gearbox shaft according to the mark.

After installing a new wiper or replacing the gearbox, it is possible that the wiper blades, moving, will extend beyond the glass.

This problem cannot be eliminated by rearranging the brushes on the splines.

It is necessary to rearrange the crank on the gearbox shaft to ensure proper operation of the cleaner.

Checking and replacing the windshield wiper relay

To create intermittent wiper operation, an electronic relay 524.3747 is used.

Scheme for checking a windshield wiper on a car: A - low speed; B - high speed; 1 - additional jumper; 2 - plug connector of the wiring harness to the wiper switch

If the windshield wiper fails, it is necessary to determine whether the windshield wiper or the switch is faulty.

To do this, you need to disconnect the plug block from the switch (it is located under the instrument panel) and connect the plug tips of the block (which remains on the wiring harness going to the wiper), as shown in the figure, “A” for low speed and, “B » for high speed.

If the windshield wiper starts to operate, this indicates a faulty switch, and if not, the windshield wiper is faulty.

Scheme for checking a windshield wiper removed from a car: A - low speed; B - high speed; 1 - plug connector; 2 - control lamp; 3 - battery

To check the functionality of the windshield wiper removed from the car, it is necessary to connect the windshield wiper connector according to the diagram shown in the figure (lamp 2 will blink).

If the windshield wiper operates at low and high speeds, but does not work in intermittent mode, check the serviceability of the intermittent operation relay.

Checking and replacing the windshield wiper relay

To replace the windshield wiper relay in the engine compartment (above the expansion tank), remove the connecting block from the relay terminals
