I have a problem...my son pushed the headliner to the sunroof while it was closed and a plastic piece broke off. I opened the sunroof, and now it wont close. it starts to close but gets stuck and stops after moving maybe two inches. Do i have to take the headliner off to fix this? or should i take it to a shop to get fixed? Thanks for the help

 

Welcome in,do you have a picture of the piece or can you explain where the piece was?
