Did you actually check the bulbs? I believe your brake lights, signal lights, hazards all use the same bulb for each side.
Your brake lights may be your brake switch just above your brake pedal. The signals could be your electronic flasher module (EFM) located under the dash near the steering column. Your hazards may be affected by the EFM, but not likely and the switch for your hazards may be faulty
If you have trailer lights make sure you don't have a short in the connector or harness. You obviously have a short somewhere after the fuse. Try unlpugging each running light. to see if its in the light connecter. also check the side markers
Usually one of the holes in the marker light where screw goes in, has metal contact where screw meets light, but if not, and they are not push in wire connection type from behind, then just run your white wire up through hole in housing, and bare the end & tighten it up under screw holding light to body. White should be ground, brown should be power.
You can purcahse a tester which will connect into the F-150's wiring harnes. If the led lights up, the problem is witht he trailer's wiring harness. this tester will indicate the proper operation of the brake light and turn signals.
I had a similar nagging problem once, though I do not recall the dashlights being involved. For me, the lines from the brakes went up the steering column to the turn signal. I pulled the wheel and inspected all the connections, and just like that everything worked again. I believe I could have tugged on the wiring harness without pulling hte wheel and obtained the same results.
Brake light switch, located on upper brake pedal should be checked, that is most likely your brake light issue, but U say tail lights aren't working, but running lights do, tail lights and running lights I would consider to be the same, so can u clarify that for me? Let me know how the u do w/ brake light switch, and if u have issue w/ tail lights?
