Very easy fix. First step is to take off the sun visors. step 2 take off all grab handles (top of door entry) now you need to carefully pull the wishield pillar mouldings off ( the clip is about half way down, don't force it or it will break. Next take of the trim piece around the sunroof.. pull it from the front into the centre of the sunroof and it will just fall off. once all that is done you can carefully pull the roof liner down. after that you should be able to pull the sunroof shade back to where it should be and inspect why it happened in the first place. Good Luck.
