Test 1, Wipers Do Not Operate
- Turn ignition off. Unplug connector from wiper/washer switch. Turn ignition on. Using a test light, check for battery voltage at harness connector terminal E5 (Yellow wire). If battery voltage exists, go to next step. If battery voltage does not exist, check for open circuit in Yellow wire from fuse panel.
- Unplug 3-pin connector from wiper motor. Connect test light between battery voltage and harness connector terminal "C" (Black wire). See Fig 1
. If test light glows, go to next step. If test light does not glow, repair Black wire between 3-pin connector and ground.

- Reconnect wiring to wiper/washer switch. Unplug 6-pin connector from wiper motor. Using test light, check for battery voltage at 6-pin connector terminal "C" (Dark Green wire). If battery voltage exists, go to next step. If battery voltage does not exist, check for open circuit in Dark Green wire between switch and wiper motor. If wire is okay, replace switch.
- Set wiper switch to LO position. Using test light, check for battery voltage at 6-pin connector terminal "B" (Gray wire). If battery voltage exists, go to next step. If battery voltage does not exist, check for open in Gray wire between switch and wiper motor. If wire is okay, replace switch.
- Check for continuity between terminal "A" (Yellow wire) on 6-pin connector and terminal "B" (Yellow wire) on 3-pin connector. If continuity exists, go to next step. If continuity does not exist, repair open in Yellow wire.
- Check for poor connections at wiper motor. If connections are okay, replace wiper motor.
