I have a 1993 MBZ 400E that started blowing the fuse when I turn the windshield wiper on. The wiper goes to the upright position and the fuse blows. I can pull the wiper down into the parked position, replace the fuse, wiper goes up, fuse blows, etc. I am thinking it's a short in motor.

Trying to find pictures/instructions for replacing the motor. Can anyone help???

Dealer says it's a 3 hour job.
