Description & Operation
All models have a 2-speed wiper system with intermittent feature. The windshield wiper relay for 320i and 633CSi models is located near the left kick panel next to the turn signal flasher.
The wiper switch is on the right side of the steering column. As the lever is moved upward, the wipers run intermittently, at low speed and at high speed. Pulling the lever toward the steering wheel operates the washer pump.
