Normal Operation
Under normal operation, the front windshield wiper motor receives power through circuit 950 (WH/BK) and circuit 1002 (BK/PK). The front windshield wiper motor is grounded through circuits 1203 (BK/LB) and 1205 (BK). The front windshield wiper motor receives open and ground inputs from the steering column multifunction switch through circuits 671 (LB), 680 (LB/OG), 682 (DB) and 684 (PK/YE) to activate the wipers to the appropriate speeds.
