Look behind your right (passenger side) kick pannel inside the cab, you should see a vent which is run by engine vaccume, I think this vent only opens when its on max AC. I'm not sure, I've never had a truck with AC that worked, but if it does open only on max AC this I think would be the same as cracking a window open.
