I had that happen 2 to 3 years ago .They had to tear out the dash! I was smart and had the long term warranty. It was not a cheap fix. :thread:

hay i kinda have a simaluar prob ,when i get in my car and set it to 72 when its hot out and cold air comes out, and the oposite when its cold out hot air comes out, except after a half hour it starts to put out ac when its only 30 out , even if the air temp inside is 50, the only way i can get heat is if its on 90? any takers? im thinking its the radio heating the air next to the temp sence and sending false readings.
