I am having a problem with my headliner in my '07 TB LT. Behind the sunroof, where the dome light is, the headliner keeps sagging/dropping down. I can push up on it and it will stay for about a minute and then I can hear the "velcro" releasing and it drops back down. It is only dropping about 2-3 inches, but it is really annoying. Does anyone have any ideas on how to fix this? Can I pull out the dome light and re-attach it somehow? Any help would be appreciated, and I am enjoying this site. Thanks.
