I have been hearing this nerve-wracking vibration noise from the interior of my car and it's been driving me CRAZY! I checked to make sure it was not the glove box, the front dash slots (where a radio would go if I had one), the little slot down by the cig. lighter, the little slot by the fog light switch, etc, etc. I have not been able to figure it out until today. It's my freakin' headliner (I guess that's what you would call it)!!! Basically it's the interior roof of my car. As long as I drive with my hand on the ceiling, I don't get the noise! Anyone have any ideas as to how to keep this from rattling without keeping my hand in the air when I drive?
