I live 25 miles from the near RV service.
I had the same problem, the AC was working but blowing out hot air. I tracked it down to a little black box (hot water flow control valve for heater) in front of the radiator, a heater hose goes in one side and out the other then on to a larger black box (heater radiator). I took the small black box apart and had to special order a new hot water control valve and replaced it, problem solved. Though the AC part was doing it's job cooling the water leaking by the water valve heated the air right back up thus hot air out the inside vents. I also checked the clutch on the compressor, had to crawl under the MH and look up to see the compressor mine was working as it should that is why I kept hunting and found the bad water control valve.
