Ignition ON, command the Windshield Washer Relay Command ON and OFF with a scan tool. Observe that the KR11 windshield washer pump relay clicks and the G24 windshield washer pump runs.
- If the KR11 windshield washer pump relay does not work, replace the X50A underhood fuse block.
- If the KR11 windshield washer pump relay works, but the G24 windshield washer pump does not run, test the washer fluid pump control circuit and the washer fluid pump ground circuit.
- If all circuits test normal, replace the G24 windshield washer pump.
