I've been playing around with my AC, and here is what I discovered, which MAY answer some other people's questions.
If you turn the knob to the colder settings, but don't turn the AC button on, it does blow some cooler aid (which is what I have experienced in EVERY vehicle I've ever owned), but you also get sort of a musty like smell as well. For those of you who have the AC button on, and are getting cool air (not cold), and the musty smell, I'm wondering if the AC compressor is actually not functioning in this case for you. The button is on telling you it's on, but it's not actually functioning, and therefor you don't actually have any AC.
I've also noticed that when the AC is on, my car seems to have a varying degree of coldness output, even when on the coldest Max AC setting. Sometimes it just seems to be cooler than without the AC button on, other times it seems to be blowing out pretty cold air. The test I always do it holding my hand up to a vent. At it's coldest, it does cool my hand down enough that I actually want to remove it because it seems like it's getting too cold. When it doesn't seem to be functioning at it's coldest, I could leave my hand on the vent all day long.
This morning I found it kind of odd (even though my car had been sitting outside all day yesterday in the sun), that when I turned the AC on this morning (again, using Max AC setting), it was blowing relatively hot air out for about a good 10 seconds or so before it started to blow out cooler air.
It's not officially summer yet, so I'm still using the AC off and on, but I'm not sure I'm satisfied with how it's performing, so I may need to take my car in for service for this issue. With that said, I do recall saying right where I got the car (and I took delivery last August), that the AC didn't at all feel like it was outputting cold air like it should, like I never wanted to turn the fan setting off from "4", because then it would get too warm.
