I remember in college a friend had an Audi where all four windows were electric and didn't work and no air conditioning. We would just open the doors for a quick breeze.
Off track, yeah that is the bs they give, any window that doesn't work is "off track". Sort of the lazy definition.
So did you check the fuses? Getting a window on track is not too hard, keeping it on track can be harder. There are many good junk yard resources around here (Crazy Rays has a good Hyundai section).
