The failed components are the plastic buttons mounted on the dash windshield and light controls. All the buttons are cracked and some of them have fallen off and cannot be reattached. Once a button falls off you cannot use turn on the windshield wiper. I can not buy the buttons without buying the entire switch assembly.
