Abstract
This disclosure details motor vehicle wiper systems and associated methods for heating wiper blades of the wiper systems. In exemplary embodiments, a wiper blade of a wiper may include a beam blade portion, a tip portion, and a heater element. Each of the beam blade portion, the tip portion, and the heater element may include a different material composition. The material composition of the heater element, for example, may include a thermally conductive polymer. The temperature of the blade may be regulated by adjusting a current flow through the thermally conductive polymer heater element.
