My headliner is falling not along the front windshield or the rear, but in the middle! When I drive it makes a ungodly amount of creaking and noise. Does anyone know how to fix this? I was thinking you might be able to take the light out and shoot glue up in there or something?

but no seriously mixedbreed was right. It shouldnt be that hard to take it out and get it to adhere back to the roof of the car with a little bit of the 3m treatment
