Rear window completely off track

I was just driving down the road today when my passenger window completely fell into the door. Someone told me that it is just off its track. Coincidently, I just went out of warranty 1000 miles ago. Any ideas of what I am in for at the dealership?

It sound like it need a window regulator. You can try and get the dealership to warrenty it since you are only 1000 miles out (sometimes).
