Note the diagram, yellow wire is voltage for right rear turn. If the right rear stop and tail lamp work, the ground isn't the problem. Does the right front turn, work?
At that yellow wire use a test lite to check for voltage, right rear turn on. The bcm supplies that voltage, I'm not saying the bcm is faulty. Have to test further.
