Abstract
An electric heating grid extends from the middle of one side of the windshield, down that side to the bottom of the windshield, and from there across the bottom to the opposite side. The grid is operated by a control circuit having an on-off switch that is accessible to the vehicle operator. The control circuit includes a switch for sensing ambient outdoor temperature so as to allow the grid to be operated only when the outdoor temperature is below a threshold that distinguishes wintertime from non-wintertime conditions.
