E30 windshield wipers not working

Recommended Posts

Hi!

i recently purchased an e30 320i 1990 and the windscreen wipers have stopped working. I was getting getting gas and turned the car off mid wiper cycle (they were in the middle of the windscreen). When I turned the car back on they wouldn't move. 

When the wipers are switched on the wiper motor makes a humming sound but the wipers do not move. When I switch between wiper speeds the wiper motor makes a higher/lower pitch humming sound.

when I remove the wiper relay, they motor does not work at all (obviously).

any idea what this could be?

The nut may have come loose on the motor shaft, not sure how to get to it in one of those, but it holds the small arm on that connects to the linkage. If you can see it, turn the wipers on and see if the shaft is turning.

You were right on the money mate. Had a look inside the motor and the nut had come loose! Thanks
