My right tail light is out but my brake light and turn signal still work and they run of the same bulb which is strange, I changed the bulb and checked the fuses and it all checks out but still no tail light. Any and every suggestion would help.
Try the Socket - That was my issue (not the bulb or wiring - the sockets come out pretty easy and you can buy another or just use a small screw driver to adjust / pry)
Also not just the back socket but the front also since it is has a running ground (the ground runs through the front to the back etc). Mine was the front Drivers that was causing issues for the rear drivers - talk about annoying to figure out.
