OK. I have a good grasp on whats going on. The interior lights on any of my three enclosed trailers do not work with my 2012 Dodge Ram 2500 Laramie. It is factory wired with only about 10,000 miles on it. There is no constant power in the 7 way plug at the rear. I have looked in the owners manual to find a fuse that may be the problem and it states a fuse in the box by the number, but the number in the manual is nowhere to be found in the fuse box. All three trailers lights do work with other vehicles. All the exterior lights work with this dodge but the interior courtesy lights do not.
Sorry, I just saw that Robert started to help you. Disregard my reply.
Hello, the fuse for the constant power back at the trailer connector is fuse J1. I'm posting a wiring diagram for the Trailer 7-way connector and also a fuse location chart so that you can find the fuses...
If the fuse is good, then I recommend taking the vehicle to the dealer for diagnosis. It is very possible that the TIPM (Totally Integrated Power Module) has disabled the circuit due to a wiring issue. When the TIPM disables a circuit, it usually won't come back up until the problem is fixed and the codes are cleared out from memory... Unfortunately, a generic scanner is not able to access codes from the TIPM module so the dealer must do this....
Here is the diagram and fuse locations as promised:

Ok so here is my dilemma. I have your diagram and my fuse box and they dont match. There is no such J1 fuse in my fuse box. I have looked and looked over it but I have yet to find a match. Is the fuse box your talking about in a different location?
Ok that is the fuse box that I am in. I have incliuded the fuse box panel picture for you to review. It does list a J1 on the panel legend but there is no corresponding J1 fuse in the diagram in the same panel.
ok here it is.
there is no J 1 position. thanks
Ok, I'll take pictures of a new truck fuse panel tomorrow and will post the information for you asap. If I don't reply in a timely manner tomorrow, please post a reply to keep me on track....Thanks,Rob
I finally had a chance to take some pics, I have a pic of the Fuse Panel Door and also the fuse panel itself with the J1 Fuse circled in red...
Check to be sure that the J1 Fuse is present and also if there, look at it carefully to see if it is blown. If it is missing, of course you will need to put one in...
If the fuse is there and looks good, let me know, We can continue if necessary....
