Troubleshooting No Trailer Running Lights for 2017 Nissan Pathfinder
Question:
the turn break and bakup lights work on the trailer. the tail marker lights do not. i have checked the fuses, brought to a u-haul dealer- the go to guy for trailer hitches and wiring, the nissan dealer, and my local mechanic all have checked and swapped out the fuses. there is one setup by the windshield, top left of the engine dept., one right in front by the headlight, another behind that, then a box in the cab. all lights minus the running-maqrker/tail lights are working. tried three different trailers and a plugand-4 way addapter- that shows power to that lightset-it doesnt. any idea why? whats your warrantee?

I know you said you checked fuses but did you check relays? The "no running lights" problem is pretty common on Nissan vehicles like your Pathfinder and the issue is typically a missing or bad relay for this circuit. It's so common we almost get this question daily.
For the needed relay you can use one of the blue relays from the Curt Relay Kit # C57000.
I attached a picture where the harness is that has the running light circuit relay you'd need to find.
