Transport Canada Recall - 2015370 - THOR MOTOR COACH

Certain motorhomes were built with a defective heater and air conditioning control head. If the controller was subjected to a spike in voltage, it could lock the heater and air conditioning control head in the position that it was set on at the time of the spike. This would not give the operator the ability to change the air flow to the defrost/defog setting. Without the ability to defrost/defog their windshield, visibility could be reduced, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will install an additional wiring harness that will prevent a voltage spike and voltage overload of the control head.
