The temperature control knob on my Grand Prix won't work. It only blows hot air no matter what I set it on. A/C system is charged and has freon, I checked. Any Ideas?

In the middle of winter you can't get the A/C to blow. But if you're in a warmer climate...
Does the compressor run?
Is there anything disconnected, broken, etc?

If you really mean "hot" air is blowing, the vacuum line is severed or actuator (a small door that's controlled) is broken. These doors are vacuum controlled, air sucks them closed or open. It's located up under the dash I believe on this model. If you aren't comfortable looking at a Haynes manual and taking apart your dash, you're going to have to take it in.
