My window does this too...I hate that.

Take of the driver side door panel. There are two "portholes" on the lower portion of the door. Lower the window until your see the track. One is easily seen, the other is behind the speaker, so take the speaker out.

It's a 10mm bolt, an extension will make it a lot easier to get too. Loosen the bolts and play with the window. It's a pain the ass.
