The AC doesn't work as good as it should. In my experience with other vehicles, when the outside temperature is about 70 - 80 degrees, you can't run Max AC for very long or you'll freeze your butt off! Well, not so with this car. I had the heater core out a few months ago and saw nothing constricting the air. Could there be a vacuum actuated flap thats stuck? I don't know. All I know is I hate working on this car: it took me over an hour to get 1 hose clamp on. Just bad design. Ok, done ranting
