D1-D3:

D3-D4:

D4-D6:

Normal Operation
The rear wiper motor is controlled by the SJB. The SJB supplies power to the rear wiper motor through circuit 411 (BK/LB) from the integrated rear wiper relay and through circuit 406 (BN/WH) from the SJB fuse 21 (10A). The multifunction switch applies ground to circuit 485 (PK/BK) for low speed wipe, or applies ground to circuit 410 (WH/OG) for intermittent wipe. The multifunction switch and the rear wiper motor is grounded through circuit 57 (BK).

Possible Causes
- circuit 410 (WH/OG) short to ground
- circuit 411 (BK/LB) short to voltage
- circuit 485 (PK/BK) short to ground
- multifunction switch
- rear wiper motor
- SJB
