does anybody else have this problem? when i push the button for the floor, floor/defrost, face, and defrost button, the motor sounds like it is turning to the right part but it doesnt stop and just keeps going and starts a constant click.. not the engine, the motor that moves the air ducts inside the dash... cuase it just started today and it is pissing me off...it only stops when i have both the face/floor button in.
