HWH air leveling issue
We have a 2003 Country Coach and We're having a problem with with our 500 series HWH air leveling where the right front airbag will not release air to lower the right front airbag of the coach for leveling. Using the HWH repair manual for the 500 series computer-controlled air leveling, I discovered there is no 12 volts reaching the solenoid, and further up stream, there is no 12 volts at the harness inside the control box. All fuses are good. The book says to change the control board which HWH tells me that this board is obsolete and the only thing I can do is send them the control board for repair and that the worst case scenario could be $925. Ebay has some, but not my model, which is AP22070. Before I do this, does anyone have iny ideas? TIA.
Followup: I later forced 12 volts to the right front "lower" solenoid and it clicked, but no air came out. I checked the exhaust port and it looks clean, so maybe the valve is faulty too. I also noticed the valve on the compressor glass bowl (the one with the metel ring you can pull out with your finger) was popping about every 20 seconds. Anyone know what this valve is for?
