If the fuse is good/not blowing, and you lost front corner/market lights, tail lights, license plate lights, and cluster & dash lights (everything), then that is probably the case. Have you taken it apart to try and clean it? Good chance you can clean it up and get it working again.
If the fuse is blowing, the you probably have a short and it's probably somewhere else but could be the switch.
