Headliner and Seat backing are falling apart

[edwardabodnar]

Well the warranty is up and now its up to me do to all the handy work...I need some help I am a DIY'er but only with directions. My headliner is sagging like crazy now and I just cat take it anymore I was wondering if anyone has done a DIY that would be great cause I have no idea how i am going to pull the whole liner through the door...also the backing on my drivers seat has popped off I assume the used a silicone or glue for it initially can anyone suggest a tube for me to pick up.

Thank you
