- Disconnect wiper/washer switch connectors. Turn ignition switch to RUN position. Connect a test light between terminal "B" and ground. If test light is on, go to next step. If test light is off, check for open in wiper fuse or circuit No. 93 (White 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 connectors. Disconnect wiper motor module connector C1. Connect a test light between C1 terminal "C" and ground. If test light is on, go to next step. If test light is off, check for open in circuit No. 91 (Gray wire). If connections and circuit are okay, replace wiper/washer switch.
- Turn wiper/washer switch to LO position. Connect a test light between connector C1 terminal "B" and ground. If test light is on, go to next step. If test light is off, check for open in circuit No. 96 (Brown wire). If connections and circuit are okay, replace wiper/washer switch.
- Use an ohmmeter to check for continuity from wiper motor module connector C1 terminal "A" to connector C2 terminal "B". If continuity is found, check for poor connection at wiper motor module connector. If connections are okay, replace or repair wiper motor. If no continuity is found, repair open in circuit No. 196 (Yellow wire).
