I noticed my Denalis air compressor was having to run a lot more often, even when no weight change was added, and it kept getting worse and worse. Finally it seemed like it was running all the time, and it was starting to sound pretty bad, so I pulled the fuse. But before I did, when I was under it trying to find the leak, it sounded like the air was rushing out as quick as it was pumping it and it sounded like it was coming from the compressor itself. Do those have a blow off valve that could be stuck open or something? I don't think its the shocks leaking, because since I pulled the fuse, the shocks haven't lost any air in them, granted I haven't tried putting a trailer on it yet either. I was hoping someone with some experience can chime in here. What would make the compressor run if no load was added to the air shocks? Is there a sensor someplace that is telling it that it is low? Thanks in advance for the help.

No, it adjusts on and off based on the ride height sensors attached to the lower control arms is my understanding. Yes its possible it has an over-pressure release valve.
