Curious if this has happened to anyone else or if you know how to fix it. When my window is rolled down or even half down it rattles around quite a bit when going over bumps and especially when closing the door. I can grab the top of the window and move it side to side (left to right). Perhaps just a loose bolt inside the door or a broken part? Any help or pictures would be great.

edit: It is a quad cab with power windows.

 

The "fuzzy" channel that the window rides in (at rear edge) has probably fallen down into the door. This happened on two of my doors.
I just removed the door panel, found the channel in the bottom of the door, and glued (RTV) it back into place. Haven't had any trouble since.

 

Cool thanks for the tip. I'll check it out when the weather gets a little warmer.

 

That is exactly what it is, I had it happen in mine, same symptoms. the strip slide down and fell off.
