Rear Washer Motor Inoperative

Possible Causes:

CAUTION: Always turn ignition off before disconnecting or connecting any control module connector. Failure to do so could result in damage to control module.
NOTE: Ensure vehicle being tested has a fully charged battery. If it does not, false symptoms may occur.
NOTE: For component location, see appropriate illustration under COMPONENT LOCATIONS  . For terminal identification, see appropriate illustration under CONNECTOR IDENTIFICATION  . For circuit and wire color identification, see WIRING DIAGRAMS  . For component removal and installation procedures, see appropriate component under REMOVAL & INSTALLATION  .
NOTE: Rear Washer Motor may also be referred to as Rear Washer Pump/Motor.
NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

Testing:

  1. Turn ignition off. Disconnect the Rear Washer Motor harness connector. Turn ignition on. Using a 12-volt test light connected to ground, probe Rear Washer Motor harness connector terminal No. 1. Activate the Rear Washers. Does test light illuminate brightly? If yes, go to next step. If no, go to step  3 .
  2. Turn ignition off. Using a 12-volt test light connected to 12 volts, probe Rear Washer Motor harness connector terminal No. 2. Does test light illuminate brightly? If yes, replace Rear Washer Motor. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS. If no, repair open in Rear Washer Motor Ground circuit. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  3. Disconnect A/C-Heater Control Module C1 harness connector. Measure resistance between A/C-Heater Control Module C1 harness connector terminal No. 5 and Rear Washer Motor harness connector terminal No. 1. Is resistance more than 5 ohms? If yes, repair open in Rear Washer Motor Control circuit. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS. If no, go to next step.
  4. Reconnect A/C-Heater Control Module C1 harness connector. Measure resistance between ground and Rear Washer Motor harness connector terminal No. 2. Is resistance less than 5 ohms? If yes, repair Rear Washer Motor Control circuit for a short to ground. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS. If no, go to next step.
  5. Reconnect Rear Washer Motor harness connector. Disconnect A/C-Heater Control Module C2 harness connector. Using a 12-volt test light connected to ground, probe A/C-Heater Control Module C2 harness connector terminal No. 7. Turn ignition on. Does test light illuminate brightly? If yes, go to next step. If no, repair open in Fused Ignition Switch Output circuit. Check Junction Block Fuse No. 25 (10-amp). If fuse is open, check Fused Ignition Switch Output circuit for a short to ground. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  6. If there are no possible causes remaining, replace Rear Washer Switch in A/C-Heater Control Module. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
