First thing I would do is disconnect the trailer from your 2006 Chevy Silverado so you can check the vehicle side connector with a circuit tester like # PTW2993. Test the right turn/brake signal. You should experience the same issue here since it sounds like you've isolated the issue to the truck and not the trailer. Make sure the connector is clean and free of any dirt or corrosion. Using a wire brush should suffice.

If the wires behind the connector are frayed, cut them off at the damaged area and re-splice back into the wiring.

Another possibility is your ground. The light grounds should also be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt bed, or folding tongue, any of these things can interrupt the ground. Running jumper wires from the light grounds to the main trailer connector ground can help.
