The multi-function switch receives power through circuit 950 (WH/BK). The windshield wiper motor receives power from the multi-function switch through circuit 28 (BK/PK) for low or intermittent speed and through circuit 56 (DB/OG) for high speed. The windshield wiper motor also receives power from the SJB fuse 25 (20A) through circuit 941 (BK/WH) for park. A return is supplied back to the multi-function switch from the windshield wiper motor through circuit 65 (DG). The windshield wiper motor and the multi-function switch are grounded through circuit 57 (BK).
Possible Causes
- Circuit 28 (BK/PK) short to voltage
- Circuit 56 (DB/OG) short to voltage
- Multi-function switch
- Windshield wiper motor
