Normal Operation
During normal operation, the windshield wiper motor receives voltage at all times through central junction box (CJB) fuse 44 (20A), circuit 950 (WH/BK). The windshield wiper motor also receives power with the ignition switch in RUN or ACC positions through CJB fuse 9 (5A), circuit 65 (DG). Ground is provided to the windshield wiper motor through circuit 938 (BK/LG). The run/park relay and high/low relay are contained in the wiper motor electronics. Mode of operation is dependant on the signal(s) received from the multifunction switch.

Possible Causes
- Fuse
- Multifunction switch
- Open in circuit 65 (DG), 950 (WH/BK), 57 (BK), 938 (BK/LG), 56 (DB/OG), 58 (WH), 61 (YE/RD) or 63 (RD)
- Ignition switch
- Windshield wiper motor
