WTF does Max A/C do?

You actually make your A/C less efficient by using recirculate with the windows down because air is being drawn out of the cabin; the same air your A/C is trying to draw in. You'll get more air flowing through the system with your window down if you let it use the outside air (which, in that scenario, is also cooler to begin with).

Try driving with a window open and hit the recirculate button on your A/C. At the same fan speed, there will be considerably less air coming out of the vents than you have in non-recirculate mode.

I must've read this 10x and I still can't figure out what you're trying to say.

Tell that to the dudes writing the instruction manuals then.
