Normal Operation
The windshield wiper motor receives inputs from the multifunction switch circuits 8-KA8 (WH/RD), 10-KA8 (GY/RD), 8-KA11 (WH/BK), and 8-KA10 (WH/GN). The windshield wiper motor module (internal) then controls the wiper run/park relay (internal) using internal circuitry to control the windshield wiper motor in conjunction with the wiper HI/LO relay (internal).

Possible Causes
- fuse(s)
- circuit 8-KA8 (WH/RD) open
- circuit 8-KA10 (WH/GN) open
- circuit 8-KA11 (WH/BK) open
- circuit 10-KA8 (GY/RD) open
- circuit 30-KA8 (RD/BU) open
- circuit 31-KA8 (BK/BU) open
- circuit 31-KA19 (BK/RD) open
- circuit 75-KA8 (YE/RD) open
- circuit 91-KA8 (BN/RD) open
- multifunction switch
- windshield wiper motor
