In this video I go over how to test and troubleshoot the wiper motor and wiper motor electronics on a BMW 7 Series E38 Early Production that uses the double relay set up. This will help you check fuses, check the relay, test power to the relay, and how to check the activation side of the relay as controlled by the general module. I also go over how to jump the wiper motor to check if this could be a failed wiper motor.
