Rear lights not working
I have a weird issue with my 2004 Ford F-150 FX4. My rear lights all stopped working. Tail lights, brake lights, and turn signals. My reverse seem to be the only thing working. I also have an issue where my radio keeps turning off then back on on its own, and my auto light on and off setting stopped working. When the radio turns off, I can't turn it back on. When I turn my lights to the manual setting, they work. My front turn signals and headlights all work. Hazards flash in front only. I have replaced the brake light fuses with no change. I'm at a loss...

I would start by looking at the wire harness blocks on the firewall low on the drivers side. They bolt together through the firewall and are subject to moisture and corrosion. They're tough to get to but all your circuits for lighting pass through there. Unbolt then one at a time clean the contacts and apply dielectric grease and bolt it back together. Good luck
