2004 grand prix heat always on

Hi all.

I just recently got a problem where my heat is always on. It seems that all of the dials work properly. When I turn on the AC, the lights light up saying the AC is on, but it still blows heat. I can control the amount of air, I also can control the direction of air flow, either through the vents or floor, windshield. But when I turn the heat/cool air dial to cold, nothing happens. The heat stays on. ANyone have any ideas?

Thanks. Bill
 


Thanks guys, I will look into both these issues. Im leaning towards the blend actuator door not functioning. Every dial on that panel works accept for the temp control dial. It seems to not move at all.
