Default AC only runs on high??

Well I just encountered a bit of a problem with my AC. And I was just bragging about how awesome it is the other day! .... anyway, when I have it on all of the settings except for high, it just barely comes out. But it does come out cold! The only time the air will really start flowing is when I switch it to the highest setting, and then it pours out ice cold. Anybody had this problem or know what I can do to fix it?

It would not be that big of a problem, but my girlfriend is alwayyyys cold and its always a fight to adjust the AC. If it only goes on full blast, she won't let me turn it on at all! haha

Mine lost all but high A/C as well
I replaced the resistor pack that is located under the hood
On the passenger side against the firewall
$30 part at Autozone

Do a search :
how to replace A/C resistor pack
They even have a YouTube on it

There is a thermal limiter in the resistor pack that will open up if it gets over heated. It prevents any speed except high. Change the resistor pack. The air that "barely comes out" is ram air.

Thanks everybody! I have a couple other things I need to fixup before I can spend money on a resistor pack, so I might have to put it off a while. Once I do it, I will let you guys know if it worked. Thanks!
