ventilation issue
Just thought i'd add my hilarious cold/hot feet story about ford trucks
I've been testing vehicles for Ford for 15yrs, and I've done the very testing that this symptom falls into on more occasions than I care to remember. I've probably logged more wind tunnel hours than most of Ford's climate engineers at this point.
Why do I care about this you say??? I now own a 2009 XLT Screw.
I just took it north for the weekend, a hot weekend here in Michigan. Friday's drive up was in the 80's and Sunday's drive home was in the 90's outside.
The drive was 3 yrs long each way and by the one hour point I was trying to find a traffic pattern to follow so that I could keep the truck in cruise control so I could pull my foot off the pedal to warm up. I was wearing NB cross trainers with a mesh front over the top of your foot. My foot literally hurt from the cold air. I've been in vehicle evaluations before and had "hot foot" during heater tests, but never cold foot to this extent.
The problem stems from too much "floor bleed" in max a/c mode, I didn't feel it as much in fresh a/c mode, but then again I was already cold. Max a/c mode is panel mode, recirc air (typically higher air flow). The amount of air that comes out of any given opening is calibrated into the vehicle during the design of the air handling system. EATC (electronic automatic temp control) works the same but is a lot "smarter" and makes adjustment based on various imputs from the driver, and numerous sensors (ambient, sunload). Since it's "smarter" it can do a lot more with the air available to it. Manual controls aren't as capable and any issues with them and typically a bit harder to solve.
I've started a complaint process with my dealer, and for the time being I'm forced to use black duct tape as a fix. Unfortunately, if this can't be fixed with a calibration change, we might be doomed to keeping our duct tape on and cutting our own air outlets in them until we get it where we like it.

Thanks for chiming in with this. I like where it's going so far anyways!!!
Is till dont have the issue and i have my AC cranked every day and i wear flipflops most days also. Just done a 2000+ in the last couple of weeks and didnt have that problem once. I can feel it a tiny bit on my toes but if i didnt think about it i wouldnt know it was doing it.
I unfortunately don't have any "pull" on my end, although I am looking to talk with one of the calibrators or an air handling engineer. I don't currently work for the company, and my company wasn't the one that designed and built the evaporator case or air handling unit.
I feel your pain though, this was the worst drive I've ever had in a Ford truck, and it's a shame because I love the truck otherwise.

I just can't stand it at all!!!
If I wear flip flops my foot gets cold.
