let me know what you find out

 

RED, ya my tweeter just fell out of its place one day I fixed it now. It must be a common thing I guess...

I had a rattle like you described on the driver's side door. It would only rattle when it was cracked about three inches. I took the door panel off and found that one of the window support bolts was really loose. I put some red lock-tite on it and retightened it. Hasn't rattled since...i did that a long time ago too.
Hope you find it...
