I completely replaced my headliner fabric over the weekend, and now my sunroof will not open all the way. The sunroof will open to the "vent-mode" and will close, but when I try to open the sunroof all the way, the motor is making noise but it only moves slightly.

When I worked on it this weekend I had to completely remove my headliner molding, and then reinstalled it after replacing the fabric. I am thinking that now something is obstructing the sunroof from opening all the way. I am planning on removing the headliner again this weekend to see if the sunroof will open without it being there, but I wanted to see if anyone had run into this issue before / had any ideas as to what I need to be looking for.

Thanks in advance.
