yeah, ive unfortunately had to do this before as well. the cables are held in by two plastic clips one at the top and one at the bottom, if you pop them out, you can get slack in the cable, but just so you know the track and motor are attached. and the rear tracks are very hard to remove, i had some frustration and cut up hands becasue of it. to get them out, i unbolted the window from the track and got it out of the way so i could barely fit it out. i replaced my drivers rear window assembly and it broke again..... i'm not looking forward to replacing it again....
*where is the junkyard, i might want some parts
