I think I tried that, but I’ll try it again.If you don't already do so, try running it in full automatic mode, in that mode I believe it switches back n forth between fresh and circulated air itself. So at least you won't have to keep messing with the buttons while you drive. How long its on a setting you like will still be up to it and the humidity level though. So yeah, the HAL9000 reference seems even more fitting now. LOL
I guess I’m just old school on a lot of this kind of stuff. I know when to turn my windshield wipers on, I know when to turn my headlights on, I know when to turn outside air on, and I know that my car is running when I walk away from it while its running.
