If the connection disengages, the windshield wipers are inoperative. Inoperative windshield wipers can contribute to reduced visibility during inclement weather.
Vehicle description: Passenger vehicles. The protective rubber boot which covers the ball joint connection between the windshield wiper motor drive arm and the windshield wiper drag link can stick to the surface of the drive arm. If the rubber boot sticks and the wiper motor is turned on, binding of the interface between the drive arm and drag link results, causing the ball joint connection to disengage.
