fuses are not blown so what is next to check?

Several issues but maybe all are connected because they all started last week. noticed no dash/panel lights or interior light one day , the next day noticed no brake lights or tail lights. however, the headlights, front parking lights and signal lights (front and rear) still work. Tested all fuses in the block and only the panel (3A) did not work even though it did not appear to be blown. Here's where it gets odd for me: All the fuses (except the panel) make my tester light up until I pull the switch to turn on the headlights/tail lights, then the tail and brake light fuse do not make the tester light up. so what is next to check? switch? If the switch has gone bad I could see how it would shut those lights down but then why would it also stop the brake light fuse from lighting up? And if not the switch then what? the truck had run fine and had just gotten a state inspection the previous week. any help would be greatly appreciated. Cade
