Troubleshooting Recommendations:

  1. Remove all connectors from the right WTC. Inspect connectors and pins for damage/defects.

    1. If no defects or damage is found, reconnect the WTC connectors and continue with next step.
    2. If defects or damage is found, repair/rectify as required.

  2. Perform wiring checks between Right window temperature sensor and R WTC.

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  3. Measure the temperature sensor resistance (refer to Windshield and Side Window Temperature Sensor Resistance Chart).

    1. If resistance is within range, go to step 6.
    2. If resistance is out of range, continue with next step.

  4. Connect spare temperature sensor on right side window.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step.

  5. Replace right side window.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step

  6. Interchange the right WTC with the left WTC to confirm faulty unit and replace if required.
  7. Do close out.
