Test B: The Wipers Stay On Continuously
PINPOINT TEST B: THE WIPERS STAY ON CONTINUOUSLYNormal Operation
During normal operation, the windshield wiper motor receives voltage at all times through battery junction box (BJB) fuse 29 (30A), circuit SBB29 (GY/RD). The windshield wiper motor also receives power with the ignition switch in RUN or ACC positions through smart junction box (SJB) fuse 5 (5A), circuit CBP05 (YE). Ground is provided to the windshield wiper motor through circuit GD121 (BK/YE) and circuit GD174 (BK/WH). The run/park and high/low relays are contained in the wiper motor electronics. Mode of operation is dependent on the signal(s) received from the multi-function switch. The windshield wiper motor receives open and ground inputs from the multi-function switch through circuits CRW17 (GN/VT), CRW18 (VT/WH), CRW19 (BU/OG) and CRW15 (BN/WH) to activate the wipers to the appropriate speeds.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Multi-function switch
- Windshield wiper motor
