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

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
