fixing a window

the window in my sisters neon came off track. and i am trying to figure out how to get it back on. ive taken the door panel off and theres not to much room to get to the window and the track. i thought i had it on and the window went up but it got off the track again. any suggestions before i take it to a shop to get fixed?

no clue, but post in a neon forum... they might know.
