My HWH leveling system is not responding
In my 2000 U270 34' WTFE Build 5756, My HWH leveling system is not responding. I took coach out for about a 15 minute drive. Upon return and parking, I can not level coach. I have engine running, air on both gauges reads about 115 psi. Tranny is in Neutral, Parking brake is on as indicated by light on dash. When I push the "AIR" button on HWH panel, nothing happens. When I push the "AIR" button twice, nothing happens. No lights come on under any condition. HWH system will not respond to Raise or Dump either. There is no light at Travel but the coach will drive if I take Parking Brake off and put tranny in D or R.. Not sure what to do next. Any advice would be appreciated. Thank you
