Only Right Turn Signal Works on Factory 7-Way Trailer Connector on 2004 Nissan Pathfinder Armada

Question:

The only pin working is the Right Turn Signal I checked all others Brake Light, Tail Light and Left Turn none are working. No 12 volts present on any pin but the Right Turn. I changed the Blue and Brown relays under the hood, but no change. Looked up inside the bottom section of the dash above the brake pedal didn’t see any fuses....... Any ideas or help would be greatly appreciated.

Using your circuit tester, test the wires in the harness behind the 7-Way. That way you can determine if the power is making it that far which would indicate a problem in the connector itself. If there is no power there as well then it still could be fuses or relays. On some Nissan vehicles there is another relay that is in the in-cab fuse box. Use the owners manual to locate all of the fuses/relays related to the tow package and make sure they are present and working.

If that one relay is missing in the in-cab panel you can obtain a replacement from Nissan.

If you determine that power makes it back to the wiring behind the connector then you would need to replace the connector itself using # C55774.

If nothing seems to correct the problem, since it is a factory 7-Way, I recommend taking it in to have it looked over by a qualified Nissan technician.
