Does anyone know if there are fuses for the trailer light wireing? I was on my way home from the Racetrack last night when my running lights on the trailer went out. All the blinkers and brake lights work, just no running lights.

When I got home I took a tester and I am getting no power to the 7 prong plug or the 4 prong plug where the running lights are. I am wondering if there is an inline fuse somewhere?


Any help is greatly appreciated.

 

My 02 has separate fuses for the trailer lights. I've read that the 06's and up have a lot less fuses due to the TIPM wiring system. But I would still think the trailer lighting would have separate fuses.

 

I have the same problem on my 01 duelly. Still scratchen my head

my 04 blew trailer tail lights. seperate for tail and brake lights .it was in the fuse box under the hood on the drivers side of the truck. Not sure if this will help.

 

Yeah my ground had started to break loose which must have blown the fuse under the hood. New fuse, fixed ground and all seems good so far for the few around town trips I have made with the trailer. We will see in a couple of w=eeks when I head out for the first out of state round if realy fixed it?

 

My night lights haven't worked for a couple of years. Truck and trailer both. All other lights work fine. All the wires appear fine, fuses, relays, all fine. Recently I gave up looking and took it to the shop paying 125$ an hour for a tech to look it over and he suggested the module. I put a stop to that and just hotwired the tail lights with a toggle switch direct from where the relay sits in the fusebox into the cab. It cost me 5$ for the switch and used some wire I had lying around.

I'll post the exact points if anyone wants to know. not complicated.
