Help..Nissan electrical gremlins just moved in..

[3VILC]

Hey guys,
Some of nissans famous electrical gremlins have just moved in to my truck. Just backing into my spot on the driveway, and reverse lights went out. Also appear to have lost power windows, volt gauge, and warning lights. All other lights and gauges seem to work, engine runs fine, can hear the glow timer relay still working. I would like to say fuse, but surely all these things wouldnt be grouped on the same fuse.
Any ideas where to start looking?
Its cold and dark now so i'll have to investigate tomorrow
