I have had this buzzing in my passenger side door every since purchase. I have an 05 Wagon. Took it to the dealer today and it looks like there is a metal brace around the pocket you use to close the door. Take out the plactic piece that houses the window switch out and place some foam around the outside of the pocket. Then place the part back in. If this is confusing let me know. I will think of a better way to explain it. It looks like there is not enough room between the pocket and the metal brace inside the door.
