Test Q2-Q4:

Normal Operation
The windshield wiper motor receives inputs from the multifunction switch circuits 31S-XL50 (BK/OG), 31S-XL51 (BK/GN), 31S-XL52 (BK/RD), and 31S-XL53 (BK/WH). The wiper motor module (internal) 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
- check circuit 31S-XL51 (BK/GN) for open
- multifunction switch
- windshield wiper motor
