My automatic sunroof is not working at all. The buttons won't even light up anymore. I have no idea where a fuse might be for it and not even sure where to begin. Any help would be greatly appreciated!!! Any ideas on a manual to help fix the sunroof?

the fuse is actually a bigger square metal fuse in the fuse compartmentabove the rest of the smaller fuses.
my sunroof isnt working either but my fuse and motor is good.
any suggestions anyone?
