The air condition system has a mind of its own. The dual personality is present wither the car has just been started or has been running a while. One side seems to blow the selected temperature. This is the passenger side of the vehicle. The other side, the driver’s side, wants to blow hot air all the time. If the temperature outside is say 80 and I want 72 in the car, the passenger side will cool down no problem BUT the driver’s side will blow hot, not warm but hot air. Seeing how the human body falls asleep in warm temperatures, I see this is a big safety problem. In the colder months, when I want just a little bit of warm air, the same occurs, it will blow hot air, not slightly warm air like I want.
