Sunroof won't open fully. Stuck closed
 

So i bought a 2005 G35 coupe and come to find out the sunroof does not open. The motor runs for about half a second then just seems to give up and stop trying to open the sunroof, whether its tilt or slide. It tilts about one inch but will not actually open, it will not slide at all. Any suggestions on what to do?

I have a 2007 g35 coupe with the same issue, only that I don't hear the motor at all. So hopefully someone knows how to fix this.

Clean the tracks something is in the way.
