Test No. 2: Wipers Run When Switch Is In Off Position
- Turn ignition switch to RUN position. Turn wiper switch off. Disconnect wiper switch 5-pin connector. Connector is located behind instrument panel, on left side of steering column. See Figure . If wiper motor continues to run, go to next step. If wiper motor stops, replace wiper switch/washer assembly.
- Measure voltage between ground and vehicle side of wiper switch connector terminal "E" (Dark Green wire). If voltage is more than one volt, go to step 4). If voltage is less than one volt, go to next step.
- Reconnect wiper switch connector. Disconnect wiper motor 5-pin connector. Measure voltage between ground and wiper motor 5-pin connector terminal "D" (Dark Green wire). If voltage is zero volts, replace wiper motor cover assembly. If voltage is present, repair short to battery in Dark Green wire between wiper motor and wiper switch connector.
- Measure voltage between ground and wiper/washer 5-pin connector terminal "D" (Gray wire). If voltage is zero volts, go to next step. If voltage is more than one volt, go to step 6).
- Reconnect wiper/washer switch connector. Disconnect wiper motor 5-pin connector. Measure voltage from ground to wiper motor connector terminal "C" (Purple wire). If voltage is zero, replace wiper motor cover assembly. If voltage is present, repair short to battery voltage in Purple wire between wiper motor and wiper switch connector.
- Reconnect wiper/washer switch connector. Disconnect wiper motor 5-pin connector. Measure voltage between ground and wiper motor connector terminal "E" (Gray wire). If more than one volt exists, repair short to battery voltage in Gray wire between wiper/washer switch and wiper motor. If voltage is less than one volt, replace wiper motor cover assembly.
