I heard a SNAP from the passenger's side as I was opening the sunroof, and then it would only pop up, but not move rearward. Actually, it tries to move rearward, but I can see that only the driver's side moves, and pulls a fraction of an inch and then it stops. So, I'm guessing that the cable on the passenger's side snapped. Any ideas or advice before taking it apart? I haven't had the sunroof apart before.
Thanks!

 

You will be pulling all the upper interior trim - be gentle with the old brittle plastic.

If that snap was the plastic gear tape, don't pull the assembly until you have the replacement unit on hand.

 

sureshot is dead-on. and check the local salvage yards for parts oh and while you over head interior is out it would be a good time to replace the fabric they usually look like ***.
