Sunroof won't close when button is press just starts to close and retracts.

What is your question?

Sunroof motor works but the sunroof stops on something and retracts like a elevator door with something blocking it. How do I check the sunroof track to see if any debri is in the track? Could this be caused by any other reason?

How long has your 2002 Cadillac Escalade EXT had this problem?
