Wiper Intermittent Operation on 2003 BMW Z4

Occassionally in heavy rain the wipers will stop working. If we turn off the engine and wait a few minutes and restart the engine the wipers will operate normally for a period of time (varies) and stop again

Probably your wiper motor is beginning to fail and when it heats up it quits working and when it cools it will start again.

I had the same problem and was told it was the wiper motor and that it was common, cost to repair >£400.00. I surfed the forums and found that there was another reason, grease contamination in the motor, took me from start to finish 1 hour to rectify and never had any issue since. it is an easy job to remove the motor.

Was this a long term fix or did u start experiencing the problem again? I am female so do not have mechanical knowledge and will have to rely on repair shop for the right answers. I will tell them of this if it has been a long term fix if not I will have to go with their recommendations. And normally its always the most expensive. :-) My car is now turning into a money pit. Let me know your thoughts. Thx
