I recently was driving with the sunroof open and when i closed it the sunshade was retracting and popped it finished closing but was sagging. we took off the roof liner and noticed the roller was no longer on the hinges. We put it back on the hinges after rolling it back up and now it still doesnt close properly.. it squeeks a little bit and retracts to about the first track guide on the sunshade. After that first one it starts sagging and not rolling up anymore. How do i fix this issue??
