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.

Possible Causes
- Fuse(s)
- Multi-function switch
- Open in circuit 65 (DG), 1002 (BK/PK), 57 (BK), 676 (PK/OG), 56 (DB/OG), 58 (WH), 61 (YE/RD) or 63 (RD)
- Ignition switch
- Windshield wiper motor
