    I had that problem once on my Pete. Replacing the purge valve solved the problem. I replaced the desiccant canister while I was under there.

    Those are easy to change, all you need to do is buy a Rebuild Kit which is about $58.00 dollars. You can change it yourself, all you need is Snap Ring Pliers and 15 minutes, you can change it without taking the Air Dryer off the truck.
