Abstract
A wiper system for a vehicle includes a frame supported by the vehicle and a wiper motor supported by the frame. The wiper system further includes a wiper arm coupled to the wiper motor and configured to be driven by the wiper motor to move in a reciprocating pattern. A water blocking member is wrapped around a portion of the frame to prevent water running along the frame from reaching the wiper motor. The blocking member is flexible and has separate free ends to enable assembly with the frame. A method of assembling the wiper system includes pressing the water blocker onto the frame at a location away from spaced apart ends of the frame.
