3. socket wrench on 10 mm unscrew the union nuts securing the wiper arms.
4. Prying with an open-end wrench or other suitable tool, remove the levers from the conical splines of the shafts. If removal is difficult, apply a penetrating lubricant to the splined surface of the axles.
5. Ring wrench at 21 mm (or candle wrench) unscrew the nuts securing the shafts of the brush levers.
6. Remove plastic bushings and rubber gaskets from the shafts.
7. Disconnect the windshield wiper wiring harness block.
8. Lifting the edge of the seal, remove the wiper wire harness from the slot in the bulkhead of the engine compartment.
9. socket wrench on 10 mm unscrew the two nuts securing the gear motor to the body.
10. Bringing the lever shafts out of the holes in the body, remove the wiper.

Installation
1. Before installation, we wash the rods with levers from dirt. Lubricate the lever pivots with grease.
2. We connect the connector block of the new gearmotor to the wiring harness block. Connect the wire to the negative terminal of the battery. Turning on the ignition, we turn on the intermittent operation of the wipers for a short time. In this case, the shaft of the motor-reducer will be set to the position corresponding to the extreme left position of the wiper blades. Turn off the ignition, disconnect the wire from the negative terminal of the battery.
3. Disconnect the gear motor connector.
4. We connect crank A with rod B. Install the lever on the splined shaft of the motor-reducer, orienting it in position so that the crank and rod are parallel.
5. Further installation of the motor-reducer is carried out in reverse order. Before mounting the brush shafts in the body holes, lubricate the threaded and splined parts of the shafts with grease.
