PINPOINT TEST B: THE WIPERS STAY ON CONTINUOUSLY

B1-B4:

Normal Operation
During normal operation, the windshield wiper motor receives voltage at all times through central junction box (CJB) circuit breaker 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 and multi-function switch 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 multi-function switch.

Possible Causes
- Multi-function switch
- Short in circuit 56 (DB/OG), 58 (WH), 61 (YE/RD) or 63 (RD)
- Windshield wiper motor
