If you have the knob turned all the way over to the hottest setting, and you hit the "AC" button, the air does not get colder, and will not get colder, until the knob is turned to the cooler side.

I would be shocked to find a car that does not fit the above.

AC dehumidifies the air (anytime you are using the defogger your AC is activated), it won't change the temperature. In my Toyota the AC light comes on whenever the defog is on and I get so annoyed when ppl say "Why in the world do you have the AC on? LOLZ"

serious question: why does the air get colder when you are on the cold setting + AC? Clearly the air is not very cold if you just set it to the coldest setting without AC (air just comes straight in from the outside basically)

? I'm not really sure where you're trying to go with these questions. Refrigerants make the air cooler. I imagine the AC system doesn't use the refrigerants when the temp setting is on high, and just uses engine heat to warm the air. Of course, I have no idea what I'm talking about, just pulling this out of my ass.
