Sunroof on a 2001 Nissan Pathfinder

[cruicad]

My sunroof is stuck open and just stopped suddenly without any previous warning of problems. It is stuck with the sunroof tilted up at the back rather than fully open. All I am really interested in doing is getting it closed and then it can stay that way. I am not sure which fuses to check, although all appear to be intact, and neither switch will operate. I suspect a bad switch but it looks next to impossible (to me anyway) to access the switch to check for continuity. Any help would be appreciated
