Normal Operation
Under normal operation, the front windshield wiper motor receives power through circuit CRW03 (VT/WH). The front windshield wiper motor is grounded through circuits B_GD108 (BK/VT) and 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.

Possible Causes
- Fuse(s)
- Open in circuits CRW17 (GN/VT), CRW18 (VT/WH), CRW19 (BU/OG), CRW08 (VT/OG), CRW03 (VT/WH), B_GD108 (BK/VT), GD120 (BK/GN) or GD145 (BK/BU)
- Inoperative multi-function switch
- Inoperative windshield wiper motor
