Washer Fluid Sensor Failure

  1. Using scan tool, access BCM SENSORS. Turn ignition on. Read WASHER FLUID LEVEL SWITCH VOLTAGE. If scan tool displays voltage greater than 4.8 volts, go to next step. If voltage is 4.8 volts or less, go to step  5 .
  2. Inspect washer fluid level switch connector. Correct as needed. Go to next step.
  3. Turn ignition off. Disconnect washer fluid level switch connector. Using ohmmeter, measure resistance is between ground and terminal No. 2 (Black wire) on switch harness connector. If resistance is less 5 ohms, go to next step. If resistance is 5 ohms or greater, repair open Black wire.
  4. Measure resistance between washer fluid level switch component connector. If resistance is less than 3500 ohms, go to next step. If resistance is 3500 ohms or greater, replace washer fluid level switch.
  5. Using scan tool, access BCM sensors. Turn ignition on. Backprobe a jumper wire between ground and terminal No. 1 (Black/Tan wire) on washer fluid level switch connector. Read WASHER FLUID LEVEL SWITCH VOLTAGE. If voltage is less than one volt, test is complete. If voltage is one volt or greater, replace Body Control Module (BCM).
