An electric heating device for heating and deicing the wiper rest zone of a vehicle windshield includes a resistance heating wire of either circular or rectangular cross-section attached to the exterior surface of the windshield along the lower edge thereof and outside the normal range of vision therethrough by means of an electrically non-conductive tape extending lengthwise of the wire. An arcuate or trapezoidal cross-section layer of electrically non-conductive sealant completely covers the tap and wire to provide water tight encapsulation thereof. The adhesive tape may be 4 provided with holes to allow the sealant to penetrate therethrough and form a mechanical interlock between the tape and windshield. The wiper blade is adapted to contact the sealant layer. The device may also be applied to the lower edge of the rear or side windows of a vehicle to melt ice or snow which may accumulate thereat.
