2000 BMW will unlock it self and all windows come down. if I do not lock it windows stay up. Why?????
It could be one of your door lock actuators failing causing the multiple issues, or the body control module. You'll need to have someone diagnose it for you. You do know if you press the middle button on the key fob and hold it a couple seconds the car will unlock and the windows all go down and the sunroof opens if you have one?
