A heated wiper system including at least one frameless, heated wiper assembly is provided. Each wiper assembly includes a flexible squeegee blade and a pair of spaced flexible backing members. The assembly includes at least one and, preferably, a pair of flexible heaters disposed between the blade and their respective backing member to convert electrical energy from a source of electrical energy (i.e., a battery) into heat. Each heater includes a heating element sufficiently dimensioned to travel substantially the entire length of its respective backing member. Wiring connects the battery to the heaters by extending through a sealed center support apparatus which connects the blade, the heaters and elongated resilient spines together between the backing members.
