Normal Operation
Under normal operation, the windshield wiper motor receives power through circuit 1671 (RD) and is grounded through circuits 1203 (BK/LB) and 1205 (BK). The front wiper motor receives open and ground inputs from the wiper switch through circuits 58 (WH), 61 (YE/RD), 63 (RD) and 950 (WH/BK) to activate the windshield wipers to the selected speeds.

Possible Causes
- Short to ground in circuits 58 (WH), 61 (YE/RD), 63 (RD), 950 (WH/BK), 1203 (BK/LB) or 1205 (BK)
- Inoperative wiper switch
- Inoperative windshield wiper motor
