RobertaVonHess Report post Posted September 23, 2013 I have a 2003 Monaco Windsor motorhome. The HWH air leveling won't dump. Share this post Link to post Share on other sites
tbutler Report post Posted September 24, 2013 Is that the only function that won't work? Can you manually lower one side at a time or lower front or back? If you can manually adjust the level by dumping air on one side or another it sounds like a malfunction in the control panel. If no control keys dump air I would look for a fuse somewhere that controls the air release valve. It is the same valve that dumps air for the brake system I believe, when you pressurize your air to drive do you get a release of air when the pressure reaches its set maximum?

hermanmullins Report post Posted September 25, 2013 Roberta, If not said before, Welcome to the Forum. We had a 98 Windsor and had the same problem. I bought both solenoid valves and when I started to replace them I found that the exhaust ports were stopped up by dirt dobbers. I cleaned them both and the air dumped just fine. I returned the valves for full credit and got some ceramic filters for the valves and never had the problem again. Hope this helps, Herman Share this post Link to post Share on other sites
