Wayne, Are you saying nether the front or the rear will come up? If that's the case, the first two possibilities are 1. the "drive" solenoid on the level low manifold could be faulty. 2. the pressure protection valve right in front of the level low manifold could be corroded and not allowing air to pass to the leveling system. Do you get the green "travel" light on the HWH panel when you are in "drive" position and HWH is off?

The pressure protection valve in question can be checked very easy. There is a blue line that attaches to the top of the valve with a "press lock" fitting. The fitting has a brass ring that when you depress it fully, and sorta press inward on the line at the same time, then you can pull the line out of the fitting. If there is no air coming out, start the bus and build full air pressure. If there still is no air present, then that valve needs changed and it is real easy to do. My bet is that valve is the problem. Ill send you pics of it.

The pics I just sent you are of a newer coach and the valve has a brass fitting on it with 3 lines. Yours won't look like that. Yours should only have the one blue line on the output side. Call me for further instructions.
