Hello, I'll post the info below on dropping the headliner. If I can help further just reply back.

Should I replace the sunroof seal? (@$90); should I RTV the ditch molding area? (@$8); How do i drop the headliner in 2008 gmc acadia. I need better instructions then the ones that can be found on the internet which say "drop roof console assembly, drop lock pillar upper trim panel, etc.
Customer: replied 7 months ago.
K Wiggins that doesnt help me. Those labeled terms mean nothing. need something more specific. I found the same instructions already online. As for fixing the leak, what have consumers remarked as a success.
Customer: replied 7 months ago.
For example what the heck is "remove the body lock upper trim panel" where is that, how big, clips? screws? bolts? compression fittings?....... the WORST descriptors and I'm a doctor and I see plenty of horrible explanations.

Dan, I just paid $5 for what?
Customer: replied 7 months ago.
Dan and K. Wiggins, I can get a year access to alldata for my car for $15. I refuse to see what knowledge I gained from spending $5?
Customer: replied 7 months ago.
