Test E: Wipers Operate At Low Speed With Front Wiper/Washer Switch In Hi Position

  1. If front wiper/washer system operation check has been performed, go to next step. If front wiper/washer system operation check has not been performed, perform front wiper/washer system operation check. See FRONT WIPER/WASHER SYSTEM OPERATION CHECK  under TROUBLE SHOOTING.
  2. Turn ignition switch to RUN position. Move front wiper/washer switch to HI position. Measure voltage between ground and front wiper motor harness connector by backprobing terminal No. 2 (Blue/Red wire). If battery voltage does not exist, go to next step. If battery voltage exists, go to step  4 .
  3. Measure voltage between ground and front wiper motor harness connector by backprobing terminal No. 3 (Blue wire). If battery voltage does not exist, go to step  5 . If battery voltage exists, go to step  6 .
  4. Replace front wiper motor. After repair, perform FRONT WIPER/WASHER SYSTEM OPERATION CHECK  under TROUBLE SHOOTING.
  5. Turn ignition switch to LOCK position. Ensure wiper switch is still in HI position. Disconnect junction block 12-pin harness connector C3. See Figure and Figure . Measure resistance between junction block harness connector C3 terminal No. 7 (Yellow/Blue wire) and terminal No. 1 (component side) of front wiper/washer switch harness connector terminal No. 1 (Blue/Red wire). If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, go to step  7 .
  6. Replace combination switch. After repair, perform FRONT WIPER/WASHER SYSTEM OPERATION CHECK  under TROUBLE SHOOTING.
  7. Measure resistance in Blue/Red wire between combination switch harness connector terminal No. 1 and front wiper motor harness connector terminal No. 2. See Figure . If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, go to step  4 . After repair, perform FRONT WIPER/WASHER SYSTEM OPERATION CHECK  under TROUBLE SHOOTING.
  8. Repair open in Blue/Red wire between combination switch and front wiper motor. After repair, perform FRONT WIPER/WASHER SYSTEM OPERATION CHECK  under TROUBLE SHOOTING.
