Abstract: A flexible sheet member is mounted to an interior surface of a vehicular windshield, with the sheet member including a serpentine resistance heater directed therethrough in electrical communication with the associated vehicle. A rheostat effects selective heating in the resistance element. Further, a modification of the invention includes directional air conduits mounted to an interior surface of the sheet member to direct heated air within the passenger compartment, wherein the tubes include conduits, and the conduits each selectively mount a cap member at an upper terminal end thereof, wherein each cap member includes a pivotally mounted directing tube to selectively direct heated air throughout the vehicular passenger compartment.
