ABSTRACT:
A windshield heating system includes a heating element installed in the defroster ductwork of a motor vehicle. An electrical driver provides electrical power to heat the heating element, thereby immediately providing heated air to the windshield of the vehicle when the vehicle is started in cold weather. The electrical power provided to the heating element can be modulated based on (1) temperature of the air before the heating element, (2) temperature of the heating element, and (3) system voltage of the vehicle.
