2003 G35 Sedan. Sunroof always worked fine. Opened it up the other day and now when I try to close it, it gets almost all the way, stops and re opens. It's not making any noises. I don't see anything in the track. Tried holding the wind deflector down but it still stops in the same place. Can't close it all the way to recalibrate it via the tilt method. Any help would be appreciated!

Have you tried "manually" closing it? Like holding the button down instead of pressing for a short time and letting it close? Just trying to get the full idea of the issue.

Perhaps repeatedly pressing the "close button" would work? Then you can use the tilt-recalibration if it works.
