PINPOINT TEST 2: THE WIPERS ARE INOPERATIVE - REAR WINDOW
Normal Operation
The rear window wiper motor receives power through circuit (L/R) and circuit (GY). The rear window wiper motor is grounded through circuit (B/W). The rear window wiper motor receives open and ground inputs from the multifunction switch through circuits (GY/Y) and (Y/V) to activate the wiper to the appropriate speeds. The multifunction switch supplies a ground input to the rear wiper motor on circuit (Y/V) when INT 1 is selected. The multifunction switch supplies ground to the rear wiper motor on circuit (Y/V) and (GY/Y) when INT 2 is selected.
