my car is a 1997 C200( w202 chassis).

The monowiper does not go back to its resting position on switching off the wiper.

it comes to rest about 5 inches above where it should be hence obstructing the field of vision on the driver's side.

i have tried to clean and lube the shafts under the plastic cover but the problem pesrsists.

any ideas what could be wrong?-i tried to search the archives but no joy so far.

thanks for your reply.

could the teeth in the transmisson for the wiper motor have worn away to cause the problem with my car?

Its possible, but it is also possible that it just needs to be reset.

Windshield wiper transmission [attached to motor] is a "steel" worm gear [screw] and a "plastic" worm wheel 3" diameter. Steel strips plastic teeth. It takes more time to remove all the plastic cladding than to dissamble the wiper assembly for inspection, cleaning & lubing.

Although mine worked with hand movement, my inde commented that when it's installed, the windshield's resistance would be enough to prevent proper operation from a bad worm wheel or motor. Slow movement indicates bad motor.

Most photos & threads are for "e" series, but I suspect your "c" is very similar.
