2003 GMC Safari. Brake lights just went out and the emergency flashers also. The bulbs are ok, I replaced the break light and emergency flasher fuses. I have a trailer hitch wiring tester and it shows they aren't working. Any suggestions?

Those post 2000 GMs have a ton of fuses. Individual fuses for left and right bulbs on some circuits, and stupid stuff like that.
Check all your fuse panels, there are at least 2, maybe more. IIRC, the one you need to check first is under the hood.
I'll see if I can test it..Switch on the brake pedal?
