Troubleshooting Trailer Running Lights Not Functioning on 2013 Nissan Frontier

Question:

I have turn signals and stop lights but no running lights on my 2013 nissan frontier I originally did but no longer. I do not have power to the factory connector at the back of the truck. Any suggestions? do I need relays as described in some posts

It's very possible that the trailer running lights relay on your 2013 Nissan Frontier has gone bad and you'd need to replace it with one of the blue relays from the Curt Relay Kit # C57000. Easiest way to test this is to swap the blue relays around in the harness that's under your dash and see if this causes the circuit to activate again. I attached a picture of where the blue relays are as well.

Another easy thing you can check is for corrosion on the trailer wiring pins on your vehicle. Corrosion is a very common culprit for trailer wiring issues. Taking some sandpaper to the pins typically takes care of that problem.
