Troubleshooting Recommendations:

  1. Perform wiring checks between Right windshield heater 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.

  2. Measure the Heater resistance. The total resistance of the anti-fog coating when measured between terminal blocks shall be 11.73-15.87 (at 19 °C-29 °C).

    1. If resistance is within range, go to step 4.
    2. If resistance is out of range, continue with next step.

  3. Replace right windshield heater.

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

  4. Replace right WTC.
  5. Do close out.
