How do you find a short in your wiring 95 Pathfinder fuse keeps blowing Tail lights and instrument panel out?

Try cleaning the ground wire on drivers side of the core support on the very top. All these items are on the same fuse so disconnect them one at a time till you find it... guages,warning light, turn signal, back up lamp, seat belt timer, inhibitor switch, and rear window defogger. I would check the back up lamp and the defogger first.
