Twice this weekend, at highway speed, I noticed the cabin temperature got much colder compared to non-highway driving.
It was about 30-40°F both times, with the heat set up at 72 AUTO (recycle off). I was quite toasty before getting on the highway but then once at high speeds it was significantly colder. I actually had to crank the heat to 80°F (!) to feel hotter. Seemed like any setting between 72 and 80 wouldn't do much. I also noticed the air around my leg was hotter, but the top vents were blowing almost cold air.
