The windshield cleaner consists of a motor reducer with rods, levers and brushes
The wiper mechanism is located under the instrument panel
On cars of previous editions with a soft top, the mechanism is mounted on the windshield frame on top.
The electric motor of the cleaner is three-brushless, with excitation from permanent magnets, two-speed
To protect against overloads, a thermobimetallic fuse is installed in it
The cleaner has three operating modes, which are activated by the right steering wheel switch. Intermittent mode is provided by relay 524.3747, installed under the instrument panel on the pedal assembly.
On cars of previous releases, a one- or two-speed electric cleaner motor was used, which did not have intermittent operation
Power was supplied to the electric motor through the fuse of unit No. 2. The cleaner switch was combined (it also controlled the washer) and was installed on the instrument panel
The windshield washer consists of a plastic tank with an electric pump, nozzles and flexible hoses
The washer is switched on by the right steering wheel switch, while power is supplied to the pump and wiper motors
Removing and disassembling the wiper
Turning off the battery
We lift the brush lever and unscrew the nut of its fastening by 10 with a key
Remove the lever from the slots together with the brush
If the lever is not removed, you can pry it with a key
Removing the protective cap
Unscrew the nut by 24 with a key and remove the bushing with a rubber gasket
We also release the brush drive from the other side
For convenience, we remove the instrument cluster from the panel without disconnecting the wires
On the right side under the instrument panel, disconnect the cleaner's wiring block
Unscrew the head by 12 three bolts securing the wiper bracket to the body
One on the side and two on top
Remove the wiper blade, carefully removing its rods from under the dashboard
We mark the relative position of the motor reducer and the crank on its shaft
Unscrew the nut by 13 with a key and, after prying with a screwdriver, remove the crank from the shaft slots
Unscrew the three bolts of mounting the bracket to the motor reducer with a key for 10 and remove the bracket
It is recommended to replace the faulty motor reducer assembly (it is possible to clean the contacts of the limit switch and replace the brushes). Bent rods are straightened.
We assemble the wiper in reverse order. At the same time, we install the crank on the gearbox shaft according to the label
Before assembling the wiper with a new motor reducer, we transfer the label to the new gearbox
We connect the gearbox wiring harness to the corresponding connecting block of the on-board network and turn on the cleaner for a short time.
Only after the electric motor stops completely, we disconnect the pad and assemble the wiper
After installing a new wiper assembly, it is possible that the cleaner brushes, moving, will go beyond the glass or stop not in the lower position
If it is not possible to eliminate the malfunction by rearranging the brush levers, it is necessary to rearrange the crank on the gearbox shaft to ensure the correct operation of the cleaner
When installing the cleaner under the panel, check (through the hole of the instrument cluster) that its rods do not touch the wires during operation
Replacing the wiper and windshield washer relays
On the right side under the instrument panel, disconnect the wiring block from the wiper relay and the windshield washer
With a phillips screwdriver, unscrew the two screws securing the relay to the pedal assembly bracket
The "mass" wire is fixed with one screw
Removing the relay
Installing a new relay in reverse order
