According to AllData, there is "a problem in the air mix control linkage, door, or motor." This is the door that switches your HVAC unit from A/C to heat, and vice versa. A problem here might have it stuck on heat even when the A/C is being used. I cannot seem to find an exploded view of the HVAC unit, but it should all be behind the dashboard.
