I finally identified the rattle i have and its where the driverside mirror meets the car. The black plastic peice is rattling against the metal and driving me crazy. Is there a TSB for this or any easy fix or should i just trail and error it?

 

Pop of the interior trim and check bolts to sideview mirror and see if they are loose. tighten if they are. If they are NOT then pull mirror off door remove mirror from housing and tighten bolts that hold remote elec. operator inside the housing. Rattle should be gone.

 

There is a thread about how to fix this (with pics and all) do a search to find it.

 

tacobill did a 10/10 writeup on how to fix this. look in that sticky
