Normal Operation
Under normal operation, the rear window wiper motor receives power through circuit 406 (BN/WH) and circuit 1002 (BK/PK). The rear window wiper motor is grounded through circuits 1203 (BK/LB) and 1205 (BK). The rear window wiper motor receives open and ground inputs from the steering column multifunction switch through circuits 410 (WH/OG) and 411 (BK/LB) to activate the wiper to the appropriate speeds.
