Abstract: A windshield heater for heating the bottom section of a vehicle windshield includes a heating element located proximate the windshield selectively energized by direct current from the electrical circuit of the vehicle. The heater may be a heating element directly adhered to the windshield. Alternatively, the heater may include a sleeve enveloping the length of the heating element and a corresponding length of compressible material to lodge the heater between the windshield and the adjacent section of a dashboard to place the heating element proximate the windshield.
