Hello, I have a 2004 F150 XLT and the passenger side tail light doesn't work whatsoever. The light does work for hazards, turn signal, or when braking. The passenger front turn signal works, so does the front and the driver sides tail light. Only the 1 tail light doesn't work. I bought a new brake light bulb and it didnt't fix it, so i swapped the drivers and passengers bulbs out, and it still didn't work. I replaced the 10 amp fuse (#36) in the fuse box. I have no idea what is causing the problem. Any help is greatly appreciated, thank you

 

Your brake light is fine, it's the parking lamp that isn't working.

It's either a damaged lamp socket or the brown wire to the socket is damaged between the socket and a splice in the harness behind the bumper.

A fuse cannot cause a single tail lamp to go out, they're all in parallel with the license plate lamps.

You'll have to open it up for inspection, test, and the repair.

 

Yes, Check the light socket carefully, I've seen the light sockets melt from the heat of the bulb.
