We had a week or two during this summer where it was 115+ and my car was parked outside during the whole day, I have tinted windows and I did crack all the windows to let some of the heat out.
My A/C blew really cold on full auto, and once on the freeway I had to turn it down it was so cold, I am usually the only person in my car so what I do to get as much air on me as possible is I close the passenger vent and the rear seat vent to direct more air on me, the biggest problem I have is my leather seats (Black) get so hot they retain the heat for a while and makes my back hot and sweaty until I sit forward and let the air get back there...........
