Normal Operation
During normal operation, the windshield wiper motor receives voltage at all times through battery junction box (BJB) fuse 1 (30A), circuit 65 (DG). The windshield wiper motor also receives power with the ignition switch in RUN or ACC positions through central junction box (CJB) fuse 33 (15A), circuit 1002 (BK/PK). Ground is provided to the windshield wiper motor through circuit 676 (PK/OG) and circuit 57 (BK). The run/park and high/low relays are contained in the wiper motor electronics. Mode of operation is dependant on the signal(s) received from the multi-function switch. When the proper input is received from the multi-function switch, the windshield wiper motor activates the washer pump by providing power through circuit 941 (BK/WH).

Possible Causes
- Multi-function switch
- Open in circuit 57 (BK) or 589 (OG)
- Washer pump
- Windshield wiper motor
