Washer Motor Will Not Operate Test

  1. Disconnect washer pump connector. Turn ignition switch to RUN position. Connect test light between terminals "A" and "B" of washer pump connector. Activate washer switch while observing test light. If test light is on, check for poor connection at washer motor connector. If connection is okay, replace washer pump. If test light is off, connect test light between terminal "A" and ground. Activate washer switch while observing test light.
  2. If test light is on, check for open or poor connection in circuit No. 227 (Dark Blue wire). If connection and circuit are okay, replace wiper motor module. If test light is off, connect test light between terminal "D" and ground. If test light is on, check for poor connection or open in circuit No. 228 (Red wire).
  3. If test light is off, use a digital voltmeter to backprobe wiper/washer switch connector between terminal "F" and ground with ignition switch in RUN position. Activate washer switch while observing voltmeter.
  4. If voltage is present, check for poor connection at wiper/washer switch connector terminal "F" and wiper motor module connector terminal "F". Also check for open in circuit No. 94 (Pink wire). If connection and circuit are okay, repair or replace wiper motor module. If voltage is not present, replace wiper/washer switch.
