What began as an intermitten problem has left my heater and a/c system not working. In a nut shell, when you turn on either the a/c of the heat nothing happens. All indicatior lights are on and you can choose temp setting however nothing comes on. It began as an intermitten problem, then began coming on less frequently and now wont turn on at all. Could it be soem type of relay problem?

There's a module that contols the heater a/c. These tend to burn out.I had one replaced recently to the tune of $200 bucks. Check with your dealer as they'll be the only ones to be able to supply and replace it.
