Normal Operation
The multifunction switch receives power through circuit 950 (WH/BK). The windshield wiper motor receives power from the multifunction switch through circuit 28 (BK/PK) for low or intermittent speed and through circuit 56 (DB/OG) for high speed. The windshield wiper motor also receives power from the SJB fuse 25 (20A) through circuit 941 (BK/WH) for returning the wipers to the park position. A return is supplied back to the multifunction switch from the windshield wiper motor through circuit 65 (DG). The windshield wiper motor is grounded through circuit 57 (BK) and the multifunction switch is grounded through circuit 57 (BK).
