Test A: The Wipers Are Inoperative - Windshield
PINPOINT TEST A: THE WIPERS ARE INOPERATIVE - WINDSHIELDNormal Operation
Under normal operation, the windshield wiper relay receives power at all times through circuit SBB20 (GN/RD). When the key is in the RUN or ACC position, the windshield wiper relay receives power from the smart junction box (SJB) through circuit CBP10 (YE/OG). The windshield wiper relay is grounded at all times through circuit GD120 (BK/GN). When the windshield wiper relay is activated, the front windshield wiper motor receives power through circuit CRW03 (VT/WH). The front windshield wiper motor is grounded through circuits GD108 (BK/VT) and GD120 (BK/GN). The multi-function switch is grounded through circuit GD145 (BK/BU). The front 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 CRW08 (VT/OG) to activate the wipers to the appropriate modes.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Windshield wiper relay
- Wiring, terminals or connectors
- Multi-function switch
- Windshield wiper motor
