ABSTRACT:
An improved windshield wiper defroster system where the buildup of ice and snow is prevented/removed. Hot air from the vehicle heating system is pressurized and delivered to a chamber formed around the wiper support structure which pressurizes the same. The hot air is thus forced out of holes in the chamber and over the wiper blade. This system utilizes pressurized hot air to maintain a wiper blade free from ice and snow thereby maximizing visibility and safety.
