WIPER MOTOR CIRCUIT CHECK

Wiper Motor Circuit Check:






1. Unplug wiper motor electrical connector.
2. With ignition switch "ON," measure voltage between wire at terminal "L" and a body ground. It should be approximately 12V.
3. If there is no voltage, check fuse or repair wiring harness.
4. With an ohmmeter, check that continuity exists between terminal "B" and ground. If not as specified, ensure that connectors and wiring are in good condition. Repair problems as needed.

WIPER MOTOR TESTING

Wiper Motor Check:






1. Connect battery positive to terminal "b" of motor connector.
2. Connect battery negative to terminal "a" of motor connector.
3. Check that motor runs at low speed.
4. Move battery negative to terminal "c" of motor connector.
5. Check that motor now runs at high speed.
6. If not as described, ensure that connections and wiring are in good condition and check again. If problem persists, replace motor.

WINDOW WASHER MOTOR TESTING

Washer Motor Testing:






1. With ignition "ON," measure voltage between wire terminal "L" and a body ground. It should be approximately 12V.
2. If there is no voltage, check fuse or repair wiring harness.
3. If terminal "L" voltage is okay, connect terminal "LO" to ground.
4. Replace washer motor if it does not operate.
