NOTE: If any BCM DTCs are set, diagnose them first before continuing.

Turn the ignition off.

Disconnect the Washer Pump Motor harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Depress the washer switch, and measure the voltage between the ground circuit and the Washer Pump Motor Control circuit at the Washer Pump Motor harness connector.

Is the voltage 12-16 Volts?

Yes
1. Replace the Washer Pump Motor. Refer to REMOVAL .
2. Perform *BODY VERIFICATION TEST .
No
1. Go to step 2).
2) MEASURE MULTI-FUNCTION SWITCH VOLTAGE

Turn the ignition on.

Depress the washer switch, and measure the voltage of the Washer Pump Motor Control circuit at the Washer Pump Motor Connector to chassis ground.

Is the voltage 12-16 volts?

Yes
1. Repair the Washer Pump Motor ground circuit for an open.
2. Perform *BODY VERIFICATION TEST .
No
1. Go to step 3).
3) MEASURE RESISTANCE ACROSS MULTI-FUNCTION SWITCH

NOTE: If any BCM DTCs are set, diagnose them first before continuing.

Turn the ignition off.

Disconnect the Multi-Function Switch harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Depress the washer switch, and measure the resistance between cavity 8 and cavity 11 of the Multi-Function Switch.

Is the resistance below 5.0 ohms?

Yes
1. Repair the Washer Pump Motor Control circuit for an open.
2. Perform *BODY VERIFICATION TEST .
No
1. Replace the Multi-Function Switch. Refer to REMOVAL .
2. Perform *BODY VERIFICATION TEST .
