There is a tool that you can get to manually operate the sunroof. It looks like a socket. I got mine from Randy Steele at epsparts.com. He also sold me the "official" lube. You can get at the motor by removing the plastic liner on the drivers side of the trunk. The electric antenna and the sunroof motor live right there. If you have something that will fit, like the tool, you can manually close the sunroof. My guess is that they like to stick open because it's easier to pull rather than push the cable.
