1. Unplug Washer Pump Connector.

- Measure resistance between terminal A at pump and a clean chassis ground. Meter should read zero ohms. If not, repair open to ground.

2. Turn ignition switch to ACCY and washer switch to ON.

- Measure voltage at washer pump connector terminal B. Meter should read battery voltage. If OK, replace washer pump. If not, go to next step.

- Measure voltage at wiper washer switch connector terminal B. Meter should read battery voltage. If OK, repair open to washer pump. If not, replace switch.
