No running lights on trailer

[joe in calif]

I picked up my 2012 Armada last night, today I took it to a BIG RV dealer where I bought 2 trailers in the past, to hook up the brake controller, No running light on the trailer, everything on the Armada works. Took it back to Nissan they said the guy at the trailer has to use the Nissan wire harness with the controller or it won't work, took it back to trailer dealer, they said the only difference between their harness and Nissan's is the Nissan one has to be spliced and the one they used is plug and play. They unplugged the controller unit and still no power to the running light part of the trailer plug.The trailer dealer said there is no power at the plug under the dash for the running lights before the connector, I'm hoping it's just a fuse maybe. It's under warranty of course but I hate stuff like this. Took it back to Nissan and I have an appt next Tuesday so they can check out the thing. Any ideas of something I can check myself??
signal lights and brake lights work on the trailer, just no running lights.

Joe - does your Armada have the factory tow package? Not just the hitch, but the complete tow package? If you don't have the factory tow package, you need to add a relay; do a search on this forum and you'll read a whole lot about this, what to buy, and how to install it.

Also, double check the tow rating for your actual truck, with your options. I'm not sure about the 2012, but I know for my model year (2006), the two rating without the factory tow package was only 6500 lbs, compared to 9100 lbs with the tow package. There has been endless debate on this forum and others like titantalk about what makes that difference, and whether it really matters; ultimately you have to make that decision yourself. But, if you don't have the factory tow, you may be towing overweight with the trailer you have.

My Armada has the factory installed package, it was listed on the window sticker of extras. There is no power to the running light connmector that is under the dash of the Armada, maybe just a fuse or a disconnected wire.
The RV place said there was a resistor missing but I took it back to the dealer and all the resistors are there.
On the web site it says 8200 lbs. the top model Armada is rated at 9000. The dealer told me mine would tow 9000 lbs that's why I bought it. I think he was wrong. I'm going to talk him about that soon. But I'm still in specs as I don't tow with water on board. I plan on installing heavier rear springs to help with the sag. Thank you for your reply.
I wonder why 1 is 8200 lbs and the other is 9000 lbs and the have the same motor. The 4X4 is only around 6?00lbs according to Nissan web site.

With the factory tow pack you should have the auto leveling rear end and 3.36 rear gears. A lot of dealers are throwing on a hitch and calling it a tow package when it's really not from the factory.

I found this out when I bought my Titan.

took it to the dealer yesterday for the running light problem on the trailer connection, they had it for about 6 hours, found a bad relay, now everything works, I'm a happy camper again,.

Have you checked fuses of running lights?

It was a bad relay on the vehicle.

funny, I have the 2007 Armada and here are the following things I had to do to get the towing running and the running lights working.

added three relays under the hood.
added the connector to plug the 7 way factory port into to fit my trailer.
connected the WDH ( obviously)
added the brake controller
Then I couldn't get the running lights working and found that a relay was missing from under the dash just above the brake controller connection.

It all works great now.

*HELP*
I did same as most everyone has stated above:
wired all up, installed the three under hood relays, AND the additional relay at steering column, but STILL no running lights. Turn and brake lights work fine.

Any other suggestions? Which fuse should I check? I can't seem to find one labeled trailer running lights.

Check fuse #36, a 10 amp, located in the IPDM, under the hood.
