VEHICLE DESCRIPTION: MINI VANS. CONTAMINANTS SUCH AS WATER, SALT, AND WINDSHIELD WASHER SOLUTION CAN ENTER THE WIPER MOTOR COVER ASSEMBLY THROUGH PINHOLES ON THE EXTERIOR OF THE COVER THAT ARE USED IN THE MOLDING PROCESS. IN ADDITION, ON CERTAIN OF THE VEHICLES BUILT BETWEEN FEBRUARY AND AUGUST 2000, A SWITCH LOCATED IN THE PLASTIC COVER OF THE WIPER MOTOR GEAR CASE COULD MALFUNCTION AND OVERHEAT. EITHER OF THESE CONDITIONS COULD POTENTIALLY RESULT IN LOSS OF INTERMITTENT WIPER FUNCTION, LOSS OF WIPER PARK FUNCTION, COMPLETE LOSS OF WIPER FUNCTION, SMOKE, OR IGNITION OF THE PLASTIC COVER MATERIAL. CONTAMINANT ENTRY COULD ALSO RESULT IN UNINTENDED WIPER MOTOR OPERATION.
