yea my whole headliner is vibrating but its alot worse near the back for some reason.if i find it ill let everyone here know.one vibration i fixed was the plastic that holds the buttons for your sunroof,is to make sure its tight or else it vibrates very bad.do you have any problems with your rear deck vibrating? i do and ive found a few of them one of which being the 3rd brake light,do you know anymore back there?

ya the sunroof button is another spot. ya the rear deck does allot two. im probably going to get some sound deadener up there and see what happens.

Deadener on rear deck is a must. I even took out factory speakers and put a little foam around 3rd brake light. There really is no way to get rid of all the rattles. I have about 100 square feet of deadener in trunk and car, and still have some rattles

How did you tighten the plastic for the buttons? I'm having that same problem right now.

Deadener help a hell of alot. I eventually deadened my whole car but I found just from doing my trunk first it made a big difference.
