2002 Prius driver's window won't go all the way up.

We have a 2002 Prius with 218,000km on it. The driver's side power window has always been a bit sticky since we bought the car at 150,000 km, but today something weird happened:

While winding the window down (parked at the time), the glass shifted forward, then back, and now we can only wind it halfway up before it automatically retracts. It seems by the wear lines that the window is shifted forward about one centimeter (half an inch).

Question is: Does anyone have schematics or photos for taking apart a door panel and window regulator? I'd rather not go to a dealership for this, but I'd also rathe rnot make some stupid mistake and wreck the door completely.

Thanks,

Don
