In my 1998 in the toilet room at the front there was a panel at the ceiling you could remove to access the air ram and regulator. At least I think that's how I remember it. Cindy was concerned about getting stuck in the bedroom so I kept a screwdriver and small crescent wrench to release the air pressure if the door wouldn't open. I think there is a muffler or restrictor there also that you might be able to adjust the door pressure.
