Well I finally got the air fixed by purchasing an led driver 12v dc 5amp power supply that fit into the control box and that fixed the thermostat and controls. I thought that the control board was faulty but after looking closely at the wiring I found that one of the fan wires was on the wrong post and once that was corrected and the new supply it all works as it should.
When I purchased the coach it had been in to a local rv center to find out what all was wrong with it. One of the AC would run all the time when the power was on to it and they determined that the thermostat was bad. I did order a thermostat and plugged in before troubleshooting and so i now have a spare thermostat in case it actually does fail. The 12v dc supply board is no longer available so changing to a different supply was an easy and cheap ($16) fix.
