Hi, the vents are vacuum operated, when you switch from one mode to another the vacuum turns on and shuts off depending on which mode you are in. So knowing this look for the vacuum lines running to the control head, and make sure the rubber hoses are still good. if it is an 83, chances are good that replacement is in order, please get back to me for clarification if necessary, and we can discuss this further.......Michael
