My passengers side back door does not lock or unlock with the other 3 doors i could hear a vibrating noise coming from the passenger side trunk wall removed the carpet wall and hanging there is an actuator its still connected to the vacum lines and it works but it is not connected to anything just hanging there ? anyone know how to reconnect it and what it does I am assuming its what the rear passenger door doesnt lock ? anyone know how i should reattach it ? also i did have a link to a on line repair guide for my 126 anyone know the link ?
Thanks

If its like my car, that vacuum actuator moves the pin that locks/unlocks the gas filler door. It should be reattached. Your passenger door issue is probably a different problem.
