No Power To 12 Volt Pin On 7-Way Of a GM Truck

Question:

I no longer have 12v power to the interior trailer lights. The stud pins under the hood both have power and the wires are connected to them. Is there another fuse somewhere else for the 12v trailer power? All of the external lights work

Expert Reply:

I did not see where you listed the year, make, and model of your tow vehicle which I would need in order to confirm the fuse location (if present) but these are almost always listed in the owner's manual so that is where I recommend that you look. If you already checked the M8 stud on the fuse box then you best option is to just run a new 12 volt power wire of your own with part # RM-156-75.
