This invention relates to a new and useful improvement in a wiper blade and blade carrier which is electrically heated for use on the windshields of vehicles, such as automobiles, trucks, trains, boats, airplanes and the like so as to prevent the accumulation of ice, sleet or snow on the wiper blade and wiper blade carrier. More particularly, this invention has references to an improved heating arrangement designed to be used in windshield wiper assemblies with minimum modification or redesign of blade supporting, oscillating means, etc. A heating element of resistance wire is disposed the entire length of the passageway of the wiper blade and beyond into the blade carrier. The heating arrangement is connected to the vehicle battery to heat the heating element allowing the entire outer circumference of the entire wiper blade body and blade carrier to melt frozen precipitation on the wiper and blade carrier.
