Trailer brake and turn signal lights not working

Postby parrotheadz » Sat Apr 09, 2011 2:38 pm

The only lights that work are the running lights. I have read a few things about the BCM and sub harness fuses. I have checked all fuses and relays that are listed for trailer towing and all are good. So any input on what may be the cause would be great.

One way to check if the problem is in the trailer is to take a battery charger and put the ground on the tongue and touch the positive terminal to each pin. also you can also pick up an item called de-bug plug from the auto parts store. it plugs into the harness or your truck and lights up if the chosen function is working properly.

Trailer is good hooked it up to another truck. Testing the harness at the rear of the path all I am getting is power 12volts to the tail lights. And from what I have found online there are two more fuses in a sub harness that are not listed in the service manual. That is what I hope is true. Thanks for the help. Cheers.

Did you check all the fuses in all the fuse panels? (interior glove box, IPDM, and infront of IPDM). Sub harness from frame fail to pig-tail ok? If I recall, only the 7 pin has the additional harness in the right kick panel.

Ok, problem solved. Found the two blown 10 amp fuses. They are part of the BCM harness under the dash and above the steering column. The fuses are connected and have white flip caps, it actually looks like a plug at first glance. I will try and upload some photos later. After replacing the fuses trailer now has turn signals and brake lights. Still looking into what cause it to blow in the first place. Hope this helps. Cheers!

Does anyone know if the brake/turn fuse for towing is in the same location on a 2011 pathfinder. I had a shorted trailer give me the same problem. Found the running light tow fuse under the hood but cannot find a fuse for the towing brake/turn lights for anything. Thanks

There are 2 10 amp fuses under the steering wheel close to the BCM, one for the left turn signal, and one for the right. Mine were wrapped in electrical tape, and not particularly easy to find, but they are definitely there!

Hey Merc1100sc did you find anything? I am working on a 2012 pathy and having the same issue finding these fuses. Thanks.
