Troubleshooting Recommendations:

  1. Perform wiring checks between Right window 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 right side window Heater resistance. The total resistance of the anti-fog coating when measured between terminal blocks shall be 27.47 to 33.57 ohms.

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

  3. Replace the side window. Is the fault still present?

    1. If NO, do close out.
    2. If YES, continue with next step

  4. Replace WTC 2.
