Normal Operation
The windshield wiper motor receives inputs from the windshield wiper/washer switch circuits 56 (DB/OG), 58 (WH), 61 (YE/RD), and 63 (RD). The internal wiper motor module controls the internal wiper run/park relay to control the windshield wiper motor in conjunction with the internal wiper HI/LO relay. The windshield wiper motor receives voltage from circuit 2026 (RD/OG) and is grounded through circuit 1205 (BK). The windshield wiper motor internal microprocessor and relays receive voltage from circuit 2025 (RD/YE) and are grounded through circuit 1205 (BK).

Possible Causes
- Fuse(s)
- Circuit 1205 (BK) open
- Circuit 2025 (RD/YE) open or short to ground
- Circuit 2026 (RD/OG) open or short to ground
- Windshield wiper/washer switch
- Windshield wiper motor
