Troubleshooting Recommendations:

  1. Perform wiring checks between right Side Window Heater and R WTC.

    1. If wiring defects are found, repair defective wiring as required.
    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 YES, continue with next step.
    2. If NO, do close out.

  4. Interchange WTC 2 with WTC 1 and replace if necessary.
    NOTE: If the Windshield has visible signs of overheating or delamination caused by overheat, do not interchange the WTCs and simply replace affected WTC.
  5. Do close out.
