The car is equipped with a windshield wiper 60.5205 or 70.5205 with an electric drive for two brushes
The wiper motor with a gearbox and a system of drive levers is located in the engine compartment under the lower lining of the front end
The wiper is controlled by the right steering column switch 3302.3709200 or 9902.3709.
When the windshield wiper is turned off, the wiper blades are automatically laid along the lower front lining.
Wiper problems and solutions
- Cause of malfunction
Remedy
Wiper not working:
- The electric motor is faulty (clicks are periodically heard when the wiper thermal fuse is turned off)
Check the motor separately.
Disassemble the faulty motor.
Clean the collector, replace the brushes if necessary, lubricate the bearings with engine oil.
If the winding in the motor is burnt, replace the motor
- Faulty switch
Check with test lamp, replace if necessary
- Short circuit in circuits
Connect a test lamp instead of a fuse and, by disconnecting sections of the circuit, starting from the wiper, find a short circuit and eliminate it
- Jamming of the axes of the levers or hinges of the lever system (clicks are periodically heard when the wiper thermal fuse is turned off)
With the wiper removed, remove the crank from the gearbox axle and check the lever system for jamming by hand.
Lubricate all joints and axles with engine oil
- Wear of the worm gear of the gearbox (you can hear the operation of the electric motor, but the brushes do not move)
Replace the worm gear
- Defective wiper thermal fuse
Check with a test lamp, replace the fuse if necessary
Motor armature rotates at low frequency:
- Pollution or oxidation of the collector
Disassemble the motor, clean the collector
- Armature sticking in bearings
Clean the journals
- Malfunctions in the windings (see "Wiper does not work")
Check windings, replace motor if necessary
The motor is running, but the brushes are stationary:
- Weak fastening of the crank on the axis of the gearbox gear
Check the fastening of the crank. Tighten the fastening nut
- Breakage of gear teeth
Replace the reduction gear
During the operation of the windshield wiper, the brushes hit the body parts or after turning off the brushes stop too high:
- Brush levers set incorrectly
Change the setting of the brush arms
Wiper works at one speed:
- Faulty switch
Check with test lamp, replace if necessary
- Hanging brushes in the electric motor
Disassemble the motor, check the condition of the brushes, replace the motor if necessary
Removing and disassembling the wiper
Pull up the protective cap of the lever.
Unscrew the nut with the “10” key
Using sliding pliers we pull the lever off the slots.
Similarly, remove the second lever.
Prying with a thin screwdriver, we take out six plugs of the bushings of the front panel lining
Use a slotted screwdriver to unscrew the six screws securing the cladding
We take out the screws along with the plastic bushings.
Using the “24” wrench, we unscrew the nut for fastening the lining of the outer panel.
Removing the panel
Disconnect the fluid supply hose from the tee.
Using the "24" wrench, unscrew the nuts securing the two bushings of the cleaner
Remove the gaskets
Disconnect the windshield wiper block in the engine compartment
Using the “10” key, we unscrew the two bolts securing the wiper bracket to the body
Remove the wiper.
In order to remove the left link bushing from the hole in the body panel, close the hood halfway.
Use a screwdriver to unscrew the two screws and disconnect the wire ends from the bimetallic fuse.
If the brushes did not go beyond the boundaries of the windshield during the operation of the wiper, before disassembly, we mark the relative position of the gearmotor and the crank on its shaft
Use the “13” key to unscrew the nut
Remove the crank from the shaft splines
We unscrew the three screws securing the bracket to the gearmotor
Remove the link mechanism with the bracket.
Assemble and install the cleaner in reverse order.
At the same time, we put the crank on the gearbox shaft according to the mark.
After installing a new purifier or replacing the gearbox, it is possible that the purifier brushes, moving, will go beyond the limit glass cases.
Replacing the brushes on the slots will not eliminate this malfunction.
It is necessary to achieve the correct operation of the cleaner by rearranging the crank on the gearbox shaft.
Checking and replacing the wiper relay
Electronic relay 524.3747 is used to create intermittent wiper operation.
When the windscreen wiper fails, it is necessary to determine whether the fault is the wiper or the switch.
To do this, disconnect the plug from the switch (it is located under the instrument panel) and connect the plug lugs of the plug (which remained on the wiring harness going to the wiper) as shown in the figure, "A" for low speed and, "B » for high speed.
If the wiper starts working, this indicates a switch failure, and if not, the wiper is defective.
To check the operability of the wiper removed from the car, it is necessary to connect the plug-in block of the wiper according to the diagram shown in the figure (lamp 2 will flash).
If the wiper works at low and high speed, but does not work in intermittent mode, check the intermittent operation relay
To replace the wiper relay in the engine compartment (above the expansion tank), remove the connector block from the relay outputs
Use the "10" key to unscrew the bolt and remove the relay
