2008 Chevrolet silverado - air conditioner blows hot air out of drivers side and cold air out of passenger side. Extremely hot air blows out of the drivers side whenever the air is set on 60 (hotter than the max 90). It occurred once before but was fixed by a mechanic costing a couple hundred dollars, but now it has begun again. I am not sure if a part was fixed or replaced but the issue ceased and now has started again.
