I have a 2006 Monaco Windsor that Chassis AC does not turn on from the dash controls. I have had my local mechanic check out everything mechanical and if he forces the ac condenser to run I get all kinds of cold air. But the front controls just don’t activate it and we’ve come to the conclusion that there is a problem in the wiring between the front controls and the ac unit at the engine. I have checked around but don’t know where to go to get it fixed. Right now I’m in Fort Myers Florida but am heading to Minnesota sometime this spring. Any suggestions?
