I currently have lost both 1 & 2 brake/tail lights. I still have 3rd brake light and all the rest of the marker lights are working. I have reverse and turn signals in the rear. I've tried different bulbs and different bulb socket circuit board. I tested the plug in at the rear and have power at 1(blinkers), 2(constant 12v), 3 (reverse), then nothing at 4 and 6. I've ran a test light through all the fuses and have power. But I don't and can't find which one specifically goes for tails/brake. Not throwing any codes. All inside and other outside lights are working. All windows and other functions are working. I can hear the brake light switch clicking then pedal is pressed.
Can someone give some ideas or something else to check to get these working again please? I am at a total loss right now
