Hello, I'm Danny.
Quick question first. So are you saying only one side inflates? As far as venting off, the system will only vent or fill when a change in weight/ride height in the rear is detected.If only one side is working I would check for an air line leak or defective/ripped/torn leaking air bag on the non-working side. Hope this helps and thanks for using 2CarPros.
