I'm having the same problem. I just picked that car up, and didn't know any better till I really started playing with everything a few days later. I noticed that with the fan Speed control in the "O" position, that air was still coming out. I can turn the AC on and off with the Snowflake button, but air is always blowing. The other thing that I noticed is that there is no fan speed increase after position 2 1/2. 3,4, and 5 don't respond at all. It isn't a major problem as it's hot as hell here right now, but I guess I'll get it checked out a little later. It just annoying to have to keep adjusting the temperature dial to stay comfortable, because all the way cold will freeze me out even on "O". Even when it's 90+ degrees, I find myself setting the temp dial on the white dot to keep from getting too cold. I guess this will be my first service experience with the Stealership. My dealer is a big one, so hopefully they have worked on a couple XFs before.
