I had this problem with an 87 325 es. It slowly got worse, and happened
occassionally on the slow wiper speed. My solution was a new wiper
motor, which solved the problem.
That said, I wouldn't be surprised if tearing down your existing motor
and removing and replacing the 12 year old grease did the trick. I've
never done it, but I've talked to people who have.
R&R for the wiper motor is covered well in Bentley's. Two comments. Be
very careful when you remove the heater blower motor. The plastic
squirrel cage is fragile and a tight fit. Also, sliding the motor out
through the vent at the base of the windshield is a PITA. Still, it can
be done if you're persistent and the stars are properly aligned.
