I have a B5 and when i turn my wipers on I get a load buzzing/clicking noise. The noise only happens for about 1 sec as the wipers move from the off (lowest) position. 1 "buzz" per wiper cycle. The noise can be heard from inside the cabin the best, and sounds like it is coming from the round vent on the top driverside of the dash (the vent that is suppose to blow air onto the driverside window).
Other than that the wipers seem to work perfectly.

Any help would be great ! Thanks

 

Never happened to anyone ?
