Yeah, there should be one large open spot in the metal on the door where you can loosen the rear track and take it out at anything lower than half way down. With it out you can open it up some and I used duct tape to hold the window in. The front track can be reached by rolling it almost all the way down, a thin socket and extension, and you have to fit it through a hole about the same size as the socket. The hole is located like 6 or so inches from the other open spot. Once its loosened, take it out, open it up some, put some duct tape in it, and bam. Roll the window up about 1/4 way, slide the window in and mess with it until it slides into the tracks! Hope this helps. I tried pinching the tracks together with the window in to help it stay in there, and so far, so good. Its been about a month now with no problems.
Hope this helps...
