My third brake light doesn't work and I have spent many hours on it trying to troubleshoot the problem. I have tried everything that I know of without success. I tapped into the yellow brake light wire (with the blue 3rd brake light wire) and it would then function. But, it would also blink with the turn signal (of course). I have checked the voltage at the main rear harness plug to the blue wire and it is 12v but when everything is plugged together it still doesn't work. I have tried many more solutions to no avail.
Can anyone help?
