Normal Operation
During normal operation, the windshield wiper motor receives voltage at all times through central junction box (CJB) fuse 113 (30A), circuit 65 (DG). The windshield wiper motor also receives power with the ignition switch in RUN or ACC positions through CJB fuse 1 (7.5A), circuit 1002 (BK/PK). Ground is provided to the windshield wiper motor through circuit 875 (BK/LB) 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 multifunction switch.

Possible Causes
- Multifunction switch
- Open in circuit 57 (BK), 56 (DB/OG), 61 (YE/RD) or 63 (RD)
- Windshield wiper motor
