Checking my recently purchased 1997 u320 auto leveling hwh operation and let the coach level itself. Front dropped and side to side worked fine. Blinking light on panel on auto and the rear did not come up as needed. Manually raised rear till low light went off.
Turned everything off including house shutoff. Came back a couple of hours later. No movement.
Turn on house power and start engine. Rear dropped to ride height. Front stayed down.
Turned on hwh panel to first position. Then manually raised front suspension. Turned off panel. Coach stays at ride height fine.
Chassis air loses 50psi in 24 hours but the coach does not drop. My mechanic buddy fixed the chassis leaks.
I know there are experts out there. I used to be good on this stuff. Something is stuck or bad on the hwh panel or wiring and the storage leaks are storage leaks.
Need to borrow a few others brain cells if you don't mind.
Panel is well worn on its face but it seems to work. Could use a perfect face panel if someone had one for the visual niceness I guess.
Bob, Touch panel pad is available from HWH. About 12 bucks last time I bought one, give them a call.

Bob, HWH has the panels hanging on the wall in the service area. They are new replacements and very affordable.

Was the engine running at fast idle when you were leveling. In my experience the little air compressor can never raise the rear before it's automatic shutoff.
You may wish to call HWH for help.
We had a failure of HWH on our 1997 U295. The person on telephone support at HWH was excellent. He gave me some procedures to try. I reported to him that the trouble persisted. I sent the controller and the touch panel from the dashboard to HWH. A wire on the main board was loose. They diagnosed, repaired, and returned the components for less that $100. They also replaced the face on the touch panel. Turnaround was about two weeks.
See, I was correct. Lots of experience here. Thanks. Keep it coming.
Bob,
I sent you a PM.
