Normal Operation
12 volts are supplied to the rear wiper motor from the BEC fuse 55 (25A) on circuit 56 (DB/OG). 12 volts are also supplied to the rear wiper motor from the SJB fuse 7 (10A) on circuit 406 (BN/WH) for the run/park and washer internal relays. The rear wiper motor is grounded on circuit 1205 (BK). The rear wiper motor module (internal) receives inputs from the multifunction switch on circuits 488 (DG) and 485 (PK/BK), which controls the rear wiper run/park relay (internal) using internal circuitry to control the rear wiper motor. The multifunction switch is grounded on circuit 1205 (BK).
Possible Causes
- circuits 56 (DB/OG) open or short to ground
- circuit 406 (BN/WH) open or short to ground
- circuit 485 (PK/BK) open
- circuit 488 (DG) open
- circuit 1205 (BK) open
- rear wiper motor
- multifunction switch
- BEC
- SJB
