Normal Operation
Under normal operation, the front windshield wiper motor receives power through circuits SBB58 (YE/RD) and CBP45 (YE). The front windshield wiper motor is grounded through circuit GD120 (BK/GN). 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 speeds. The multi-function switch receives ground through circuit GD116 (BK/VT).
Possible Causes
- Fuse(s)
- Open in circuit SBB58 (YE/RD), CBP45 (YE), GD116 (BK/VT) or GD120 (BK/GN)
- Multi-function switch
- Windshield wiper motor
