Wipers Do Not Operate In Any Mode Test
- Disconnect wiper/washer switch connector. Turn ignition switch to RUN position. Connect a test light between wiper/washer switch connector terminal "B" and ground. If test light is on, go to next step. If test light is off, check for open in fuse No. 10 or circuit No. 93 (White wire). If fuse and circuit are okay, check for open power feed circuit No. 4 (Brown wire).
- Disconnect wiper motor module connector C2. Connect a test light between connector C2 terminal "C" and battery voltage. If test light is on, go to next step. If test light is off, check for open ground circuit No. 150 (Black wire).
- Reconnect wiper/washer switch connector. Disconnect wiper motor module connector C1. Connect a test light between connector C1 terminal "C" and ground. If test light is on, go to next step. If test light is off, check for poor connection at wiper/washer switch connector terminal "D" and for open circuit No. 95 (Dark Green wire). If connections and circuit are okay, replace wiper/washer switch.
- Turn wiper/washer switch to LO position. Connect a test light between C1 terminal "B" and ground. If test light is on, replace wiper motor module. If test light is off, check for poor connections at wiper/washer switch connector terminal "C" and for open circuit No. 91 (Gray wire). If connection and circuit are okay, replace wiper/washer switch.
