Features of the windshield cleaner and washer
The electric motor of the cleaner is two-brush, excited by permanent magnets, single-speed.
To protect against overloads, a thermobimetallic fuse is installed in it.
The purifier has two operating modes - constant and intermittent; they are turned on by the right steering column switch.
Intermittent operation is provided by a RS-514 type relay, attached with two nuts to the front left side panel.
The relay must provide 9–17 motor starts per minute at temperatures from –20 to +50°C and a supply voltage of 10 V.
(When the wiper is turned on in intermittent mode, the blades can make up to four continuous double strokes)
Resistance of the relay electromagnet winding – (66±2) Ohm, breaker winding – (23±1) Ohm.
The windshield washer consists of a polyethylene reservoir with an electric pump installed in the engine compartment, washer nozzles located on the hood, and flexible connecting hoses.
The washer is turned on by pulling the right steering column switch towards you (non-fixed position).
If the pump malfunctions, it must be replaced.
Clogged nozzles can be blown in the opposite direction or cleaned with a fishing line or a thin needle.
Removing the windshield wiper relay
The windshield wiper relay is located in the passenger compartment under the front left side trim.
Remove the upholstery.
Using a 8-inch socket, unscrew the two nuts securing the relay to the body
Pull out the relay, disconnect its block and remove the relay
Install the windshield wiper relay in reverse order.
Removing the windshield wiper
Disconnect the negative cable of the battery.
Remove the windshield wiper to replace the gear motor or deformed parts of the lever drive.
To remove the leash, use a 10mm wrench to unscrew the nut securing it.
Wiggle and remove the leash.
If the leash is difficult to remove, you can use a “17” wrench, acting as a fork puller.
To remove the windshield wiper, remove both leads.
Use a 21 wrench to unscrew the nut securing the lever bushing to the body
Removing the equalizer
Remove the rubber gasket. Similarly, release the bushing of the other lever.
In the engine compartment, disconnect the gear motor block
Using a 10mm socket, unscrew the two nuts securing the wiper bracket to the body
We lower the wiper down to remove the bushings from the body holes, while removing the bracket from the studs and moving the windshield wiper assembly to the right side of the car from under the hood lock bracket (for clarity, the air supply box has been removed).
To remove the gearmotor from the windshield wiper bracket, use a 10mm wrench to unscrew the nut securing the crank to the gearmotor shaft
Use a screwdriver and remove the crank.
Using a 10mm wrench, unscrew the three bolts securing the gearmotor to the bracket
Disconnect the bracket and gear motor.
Assemble the windshield wiper in reverse order.
Having attached the gearmotor to the bracket, connect the gearmotor block to the car wiring and turn it on for a short time
We turn off the gearmotor using the steering column switch lever and wait until the gearmotor shaft stops.
Now we put the crank on the shaft, stopped in this position, so that it is parallel to the lever of the wiper mechanism.
Removing the windshield washer
The operations are shown on a car with an injection engine (on a car with a carburetor engine, the work is similar, only the reservoir is located on the right mudguard).
Having disconnected the wires, lift the tank and disconnect the fluid supply hose from the pump.
Pulling the electric motor, we separate it from the tank
When assembling, connect the red wire with a white stripe to the electric motor terminal marked with a “+” sign
