I have a nonstop rattle that appears to be coming from the overhead controls in the headliner. It sounds like a little piece of plastic is rattling around in there. I had the dealer look into it and they couldn't find anything. If the road isn't perfectly smooth it rattles like crazy. If I push up on the back of overhead console/controls then the rattle goes away. I'd love to just pull that thing down and get a look and see if something is rattling or if I can put some felt or something in there if it's hitting something else. All I can see are two screws. I unscrewed them and tried pulling down but couldn't get it to budge. I didn't want to pull too hard, don't want to break it. Just curious if anyone knows how to remove the overhead unit. Thanks!
