A windshield wiper drive apparatus includes a non-electrical contact position detector of the wiper inwipe position. A magnet is rotated by the wiper drive gear and moves past a magnetically responsive sensor mounted within the drive housing to detect the inwipe position of the wipers. In one aspect, a rotatable cam is mounted in the housing and carries the magnet. Interengaging members on the drive gear and the cam cause rotation of the cam in only the normal direction of rotation of the drive gear. Any back movement of the drive gear through interfering contact of the wiper blades with an obstruction separates the drive gear interengaging member from the cam preventing movement of the cam.

A motor housing assembly includes a motor housing mounted to a gear housing and a brush holder assembly where the brush holder assembly is fixed in position by the junction between the motor housing and the gearbox. In one embodiment, a gasket is mechanically attached to the brush holder assembly via detents, and is compressed between the motor housing and gearbox when the two are assembled together.

A wiper drive apparatus includes a drive gear rotated by a motor, a lead frame carried on a cover attachable to the motor or motor gear and including a circumferentially of discrete conductive traces, and a park switch bridge rotatably mounted on the cover and carrying a circumferentially of spaced contacts, each slidable over conductive traces to open and close a circuit to the drive motor as the park switch bridge is engaged by and rotated by the drive gear. Each contact is carried on a beam projecting from a circumferentially of radially extending arms forming the park switch bridge. A drive pin carried on the drive gear engages successive arms to rotate the park switch bridge 90&deg; for each revolution of the drive gear to bring a different contact into electrical connection with the conductive traces without requiring additional tooling for the lead frame or the park switch bridge itself.
