Thread: Heating/AC problem

So recently my car seems to have developed a weird problem. I can turn the fan speed down, I can change where the air is coming from, but I CANNOT change the temperature. It is stuck on hot. And I mean hot. Even when I turn air conditioning on, it's hot. I don't know what the problem could be, but now that it is getting warmer out here in wisconsin, I'd like to turn the heat off.

blend door actuator took a dump. http://www.grandprixforums.net/blend...ent-21941.html

it could be.
