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