Factory sunroof doesn't close, no one else had this problem?

[OrangeCrush]

Okay, after searching and reading 23 pages in the search, the only posts about sunroofs were rattles, leaks and express sunroofs.

Last night we went to a drive-in theatre and my sunroof was open. Trying to close it, it would close a few inches and then stop. I could open it further but it simply would not close.

Anyone seen this before? I'm wondering if it's out of sync. It happened right after I replaced the battery (though I don't see any correlation in that)

Does the sunroof use cables or just an electric motor and spiralled screw track?

Thanks,

Mark
