Should have your solution. Problem is = Modern Technology!
Starting in the 1980's, pieces of cars & trucks began to be made of plastic and fibreglas, neither of which will conduct electricity.
( Originally, when cars & trucks were metal, all that was needed was to have one hot wire, because the ground was the frame of the car.)
In the 80's began separate ground wires to every electrical item.
As if that were not enough, the advent of plastic bulb holders increased the problem of " not-working-bulbs" because even the bulb holders were cheaply made.
Your solution will be to test every wire and bulb and bulb-holder, and you will find one or more problem areas for you to fix.
An electric meter or an ohm-meter will be really helpful.
Remember too, that a bulb can be bad and not look like it.
God bless your efforts.
Best Manuals Greetings, I read your question and I think Reliable-Store can help you in this. Here's the site link.

If you can't get a wiring diagram... locate the wiring harness for the lights.... use a multimeter to test the wires....even one of those ice pick type of testers with the light on it will do
have someone step on the brake.... whichever wire has voltage is the brakes. next have them turn on the right turn signal... check for voltage on the other wires... it will of course be off on . do the other side the same way. all you have left is the wire for your running lights.... turn on the parking lights for that. also if i remember right there is a connector already there for the towing package. even if you didn't order that with the vehicle it's likely there. check in the side panel where you store the jack.

SOURCE: Left rear brake light stopped working but bulb and fuses are OK.
These are Dual Function Bulbs. They control the Parking Lights and the Brake Lights. This Bulb is Burnt out on the Brake Coil inside the Bulb. I have actually seen Bulbs that were Bad But you could not Tell by jast looking at them. It should be fine with a New Bulb. Please Rate My Response! Thanks!
SOURCE: where is the fuse for the left turn signal on a 2007 Ford Freesty
replace the rear bulb it flashs fast to let you know the bulb is bad, whatever bulb is not flashing thats the bad bulb, should be a 1157 bulb or a 1156 if it has one contact it's a 1156 if two it's a 1157
