My climate control is digital. When I turn the heat on to 72, it blows hot, mostly out of the dashboard/-a/c vents, and blows too hot. I have to turn it down to 68, and then it switches from hot to clold air. When I turn the a/c on, If I don't turn it down to 68 degrees, it seems that there is heat mixed in with the air conditioning when I set it to 72. Any idea what could be the cause of the problem, and an estimated cost to repair? This is a really nice low milage as you can see vehicle. Also, while it seems the engine operates, sounds good, the pickup is NOT what it should be, any suggestions on how to improve that?

Most of the time this is caused by the temp sensor in the dash, try blast of air from a computer air duster in the intake grille. If not probably needs to be replaced. Cost? Uncertain. Dont even think the part is available...
