Last night I partially rolled down my rear window on my passenger side (I have a 4 door GT), and when I tried to roll it up, it made a sort of brief grinding/clunking noise. I didn't know it was, so I tried to roll the window down and then up. It went down more, but it wouldn't go up. When I would try to get it to go up, it would make the same noise. Now the window is free floating in its track and it's all the way down (I can manually pull it up, but it falls back down).

Any suggestions as to what the problem might be? I looked at the window motor replacement how-to thread (http://www.grandamgt.com/forum/showthread.php?t=40842), but I'm not sure whether that's the problem or whether it's something else. When the motor dies, will it still make a clunking noise when I try to roll the window up?

If the window is free floating then the guide clips or sash have broken. They attach the window to the regulator. The motor might still be ok, the clunking noise could be because the window is no longer attached to the regulator.

You will have to take the door panel off to see whats going on.

It turns out that the window was still connected to the guide. The problem was that the plastic bracket the pulls the window up broke. When the wire moving up would move, the window was no longer connected to it. That's what made it free floating. The motor was fine. I temporarily fixed it with some clamps that serve the same purpose as the plastic pieces until the new window regulator set arrives off eBay.

Here is a picture of what happened:
