Abstract
A defroster and a method for the installation of a defroster of the resistive type specifically designed to be installed on the rear window of a completely assembled motor vehicle, comprising heating conductors in the form of thin pre-glued strips of solid copper or copper alloy applied to the inside surface of the rear window in a first direction with two spaced apart connecting conductors in the traverse direction; apparatus designed for applying the various parallel heating conductors to the inside surface of the window; and a method for repairing pre-existing rear window defrosters comprising cleaning the area of the defect, applying a sufficient length of pre-glued solid copper or copper alloy overlapping the defective heating conductor securing the new strip in place and making electrical connections between the overlapping ends and the underlying heating conductor.
