SOURCE: a/c blows hot air on drivers sde
The actuator door on the driver's side is out of position and needs to be reset. Remove the negative battery cable for 1/2 hour to reset the computer. Start the HVAC system and you should be able to hear the door adjusting itself and cold should come out of the driver's side vent.

Same problem on my 98 Regal GS; remove glove box, locate the blend door actuator, (black odd shaped box with metal "ring"). Remove the box and manually turn the blend door shaft it was attached to. If you get cold air, it's the actuator you removed. About 30-40 dollars.
