Yesterday when I was driving home I took a turn quickly and heard something small fall next to my shoulder. I couldn't find whatever it was so I just kind of forgot about it. Today I went to roll down my window and it went clunk and made some more nasty noises and the window fell down inside the door.
I did some searching and couldn't find anything similar. Any idea what this could be before I take the door apart?
Also while I have access to the inside of the door is there anything I can do to make it sound better when it closes?
