TEST
3 Turn the ignition off.
Disconnect the Windshield Wiper Motor harness connector.
Disconnect the BCM C3 harness connector.
Measure the resistance of the Wiper Park Switch Sense circuit between the BCM C3
harness connector and the Wiper Motor harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 4
→ Repair the Wiper Park Switch Sense circuit for an open.
No
4 Turn the ignition off.
Disconnect the Windshield Wiper Motor harness connector.
Disconnect the BCM C3 harness connector.
Measure the resistance between ground and the Wiper Park Switch Sense circuit in
the BCM C3 harness connector.
Is the resistance below 100.0 ohms?
Yes → Repair the Wiper Park Switch Sense circuit for a short to ground.
→ Go To 5
No
5 Turn the ignition off.
Disconnect the Windshield Wiper Motor harness connector.
NOTE: Ensure the ignition switch, all lights and accessories are turned off.
Using a 12-volt test light connected to 12-volts, probe the Ground circuit in the
Windshield Wiper Motor harness connector.
Does the test light illuminate brightly?
Yes → Go To 6
→ Repair the Wiper Motor Ground circuit for an open.
No
6 Turn the ignition off.
Disconnect the Windshield Wiper Motor harness connector.
Turn the ignition on.
With the DRBIII in Inputs/Outputs, read the wiper park switch state.
Connect one end of a jumper wire to the wiper park switch sense circuit at the
windshield wiper motor harness connector.
While observing the DRBIII , connect the other end of the jumper wire to ground for
several seconds, then disconnect the jumper wire from ground.
Did the wiper park switch input change state when connected to ground then
disconnected from ground?
Yes → Replace the Wiper Motor.
→ Replace the Body Control Module.
No
