I had the same problem, it was driving me nuts, Dealer could not find the rattle, But i Knew it was there ! so i pulled off the door panel and found out the int door handle rod was touching the body metal of the door and i put some foam in there and no more rattle. also as you have read the door speakers are a problem with NBS chevy's
I had a problem with my door rattling so I pulled the door panel then closed the door and had my kids jump up and down in the back. I found out it was my window. I made sure all the window frames were tight and found a bolt was loose.. Solved the problem.. :head:
