Same thing happens to me when my wife rides with me in the summer. Has to have ac on or else....so now she knows that if its hot out, we take her car

I'm glad the wx is cooler now. Don't have to use ac. If you get the vent shades for the windows, you can drive with the fan switch on off and director switch in defrost with windows open slightly to get some air flow across the windshield for defogging with a little heat on.
