When my moonroof is slid open more than half way, it will not close on its own. It is as if one side (the passenger side) gets hung up on something. I have to put pressure on that side and "help it" close. Any thoughts on what the problem could be and/or how to get it fixed? Thanks! (naturally, this all happened during a downpour last week)

 

that happens to me, sometimes when its closed around halfway, it'll stop and i have to wait a few seconds again before it'll close

 

I had a simular problem with my sunroof, I opened it and press the button to close it and the motor works but it didn't close... Sounds like your cable might be broken or disconnected... You can purchase a kit for $50 from your local Nissan dealership and put it together yourself. Here's the link with the parts info.
