Does the window go all the way up, then down about a 1/4 way? If so, that's just your pinch mechanism.. sometimes it gets a little off. If it is, you can reset by holding your button all the way till it goes down, keep holding three seconds while its all the way down, then immediately hold till it goes all the way up, holding again about 3 seconds at the top. Should reset it.
NOW, if the damn thing just isn't working period, it might be a regulator going bad.. i had a similar problem with my 04. Start listening for weird sounds (clicks, crackling, etc).. then you'll know the motor needs to be replaced (did someone say CPO!?).
Hope this helps.
