Set the brushes to their original position by turning on the windshield wiper and turning off the ignition.
Remove both wiper arms as described above.
Remove the left side of the black plastic cover under the windshield. The cover is secured with a swivel fastener. To do this, insert a suitable coin into the slot and turn the fastener to the left. In addition, the cover is secured with two tin clips at the bottom, which also need to be removed.
Remove the cover of the electronic unit, find the two nuts securing the unit, unscrew them, remove the unit from the mounts and move it to the side to gain better access to the windshield wiper mechanism.
Remove the two bolts on the top of the mechanism and the bolts next to the wiper motor and carefully remove the mechanism from the motor.
Remove the multi-pin plug from the engine.
Use a screwdriver to pry up the windshield wiper rods where they connect to the lever axles.
Remove the three windshield wiper motor bolts. Rotate the crank arm appropriately to gain access to all bolts. The motor is now free. If the motor is being replaced, the crank arm must be removed from the motor.
When installing, pay attention to the correct position of the crank lever, because it must be directed forward before installing the engine. To do this, install the multi-pin plug and turn on the ignition. Let the engine run for a while and turn off the ignition. When it stops, the crank lever will be in the desired position.
Place and secure the engine back into the mounting frame and press the mechanism into place (lubricate with graphite ball grease if possible). When connecting the mechanism, pay attention to the following: the rod to the axis of the left lever is under the crank lever, the rod to the axis of the right lever is above the crank lever.
Secure the crank arm. It is positioned correctly when it is in the same plane as the rods on the right side.
Now install the frame (mechanism) together with the engine in the reverse order of removal. Finally, turn on the windshield wiper and check that the levers stop in the correct position.
