Doing that three button test would occasionally fix the A/C in my 2002 Concorde Limited.
Do that and find out what code it gives you. I have a list of them at home.

Problems with the auto A/C is one of the reasons I sold my Concorde. That stuff was extremely expensive and has been discontinued.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
