A window wiper assembly for a vehicle cab which has a window sash or window surround that opens either by raising and tilting or by removing the window sash. The wiper assembly includes a cam which guides the wiper arm from an operative position, where the wiper blade contacts the windowpane, to an unoperative position, where the wiper blade is moved away from the surface of the windowpane and is disposed in an out of the way position relative to the window sash to permit the opening of the window sash. A switch is also provided which senses the open window and prevents actuation of the wiper assembly. |
