You sure about that? That just wouldn't make sense, unless the Japanese want to dehumidify your stinky old sneakers. But now that you've said it, I'll be testing that one in the morning on my way home from work...
Damn skippy!!! It's like they're trying to hide something from us. Like car salesmen. Oh, wait... (uhm)
Somebody that can hear the compressor seemed really positive the AC ran with the floor-only. I'd be happy to be wrong, I prefer floor-only.
coming from winter hell, I can tell you that fogging happens from water pooling in the footwell. Hence and therefore automakers turn on AC for footwell vents behind your back to dry up the melted snow at your feet.
I still don't know why they are all stealth about it in the car. Turn on the light, then give me the option to turn the AC off. Sometimes I just want air moving without wasting the extra energy. My old car didn't have AC and it could keep the windows clear!

Like I posted on the first page, it's stupid yes, but the Protege's are exactly the same. The only modes you didnt have the A/C on even without the light on were panel, panel/floor mode. Every other mode used the a/c.
This is not true. Fogging comes from condensation of gaseous water onto cool surfaces. Most of it comes from your breath. I guarantee your that and normal humidity play a far larger role than a little water in the carpet. Your car can have perfectly dry interior and you'll get condensation on your windows, etc. when you get in the car and start breathing. More people and more condensation.
Besides, who here has ever had "pooling" of water in their cars?
Recently, after record rainfalls here, it cooled off pretty much. I got my car out of the garage and, lo and behold, the garage was much cooler than the outside temp. As soon as I pulled the car out, water started condensing on everything ... so much, in fact, that the inside of my CD player had water condensing inside (would not play or eject CD). I know this because I finally got it to eject and there was condensation and smears all over it (black rubber smears).
I went to the dealership after I got the CD out by banging a little on the sides of the stereo and wasn't sure at the time of the cause. I wanted the service writer to witness what happened when I inserted a new CD. It went in and played (coincidentally, the car had warmed and fog diminished).
I explained my thoughts, that the condensation had caused the problem (100% sure of this) yet the young guy suggested that water in the footwell was the problem (there was none). I also leave my windows open in the garage for ventilation. Idiot.
A/C will definitely dehumidify your interior moreso than without. What are you talking about?
Is your brain telling you this is the cause or did some parrot repeat it to you?

yes the fogging you're explaining is the obvious one. I'm talking about when you get to your car in -30 in the winter and your windows have a 1/2" thick layer of frost on them on the INSIDE. This comes from standing water in the footwell, and it happens wherever you get snow fall and it sticks to your boots.
You haven't really lived until you've scraped the inside of your windows with a credit card. At least you haven't lived in winter hell.
This is prevented by heating the footwell dry with AC on to take the moisture out of the inside of the car.
Judging by your jungle-like conditions, its just wet as hell and everything is getting moisture and condensation. I get water on my CD's in the spring rains too. Not sure why you were seeking someone's aid for that, the 'young guy' was probably just saying whatever to get rid of you.

wow I have never had this problem on the speed, or any other car for that matter (boom06)
Its a part of life in winter hell. You get inside the car and you take your finger and scrape off some thick frost off the inside of your windshield, and it gets stuck under your nail and its all cold and icky. Then you're trying to keep your heels on the floor mat but theres a mound of ice where your foot was yesterday. Yeah winter's really ******* great. Thank christ its over.

Yep. Verified. The floor-only vent mode triggers A/C. Saw the 2% difference in engine load on the DH when switching back & forth. Only modes with no stealth A/C trigger are indeed panel-only & panel/floor.
