my right rear turn signal and brake light have gone out. I have replaced the bulbs and have been trying to trace the wire. fuses are good. Not sure what the issue is. I have checked and swapped out the circuit board the bulbs go in and replace the wires from the mid point connector on.

Is there power to the circuit board on the tail light?

Yes there is power. I have my tail light working on the right side and the back up light working. Even plugged in another board to test. Same thing. No right turn signal. The green wire. Is what the schematic shows. Trying to find where the short might be niw. Not sure what else to check.

IF there is power to the green wire where it plugs into the circuit board, the problem may be that the connector is bad.
