Normal Operation
With the multifunction switch in the AUTO position, a ground signal is sent to the wiper motor through circuit 8-KA10 (WH/GN). When the rain sensor module senses moisture on the windshield, it sends a V+BATT signal through circuit 8-KA41 (WH/GN) to the wiper motor, which activates the windshield wipers.

Possible Causes
- circuit 8-KA10 (WH/GN) open
- circuit 8-KA41 (WH/GN) open
- circuit 31-KA19 (BK/RD) open
- circuit 31-KA41 (BK/OG) open
- circuit 75-KA41 (YE/GN) open
- multifunction switch
- rain sensor module
- wiper motor
