Did you know that if you press recirculation button, air will be recirculated 100%.
If you press again, air will be 0% recirculated, but default AUTO mode or holding
recirculation button until it blinks twice (AUTO recirculation) usually has 20-30%
air recirculation. I read that in technical papers and verified just by listening.
It's true that in hot weather recirculation LED switches on if AC is used heavily
but that shows heavy recirculation. No way to see moderate recirculation.
Maybe this is why Leaf does fog up more than my ICE bimmer. I'll have some tests.
Perfect weather for foggy windows here in February
I believe I saw something similar in my bimmer. It has REAL automatic recirculation
mode that sniffs outside air for pollutants and activates if necessary with timer
limitations in heating/cooling. It has three doors that change their angles even in
fresh mode. I'll check that as soon as I crank my 40MPG diesel monster
Anybody bored - check it out in the earliest Leafs too.
