Test Q5-Q7:

Normal Operation
The 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 wiper motor module (internal) will then control the wiper run/park relay (internal) using internal circuitry to control the wiper motor in conjunction with the wiper HI/LO relay (internal).

Possible Causes
- 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
