My driver's door window is not just the cause: it is the horizontal piece the window closes in to. I had chronic issues with the door window sticking and not lowering: the glue in this top horizontal piece had weatherstrip glue that got on the window and "glued" it closed. Cycling the up/down usually got it to release until the mechnism detached from the glass inside the door. Then, of course, the window releases and dropped down.
The window is actualy only glued in to the mechanism and keeping the window top clean and lubricated prevents the glue from sticking and holding the window in the "up" position. I have not tried to fix the rattle yet, thinking of injecting some sealant in the ends and letting all sit up and "reseal." The weatherstripping on that door is also loose, so...another project!
