Metallic Rattling Sound
 

One year old SE just tuned 30,000 miles. Car has almost been perfect. However, it has just developed a tinny, metallic rattle sound coming form the front passenger door. The sound can be heard with the window all the way up, when i lower the window about a quarter to half way, it completely stops.

Just curious if anyone else has experienced this and therefore might have a solution. Hoping that i do not have to take the door panel off to search out.
