Taillights 😵
I have a 2013 F150 fleet truck that the tail lights and tag lights stopped working but the brake lights and blinkers still work fine. I have checked the fuses under the hood as well as in the kick panel and replace all bulbs. I went through the connectors towards the rear end of the truck and cannot seem to find anything messed up. Don't know what to check next, has anyone had this problem? Please help as this truck is how I make a living, thanks in advance.
You said you you checked the plug in the rear of the truck, did you check it with a Multimeter or a test light to make sure there was power there.
If I have and electrical problem with lights I start at beginning and work my way towards the light. As far as I can tell the only fuse is #40 in the kick panel.
Do the front parking lights still work? If they do that rules out the fuse, light switch and Body Control Module. If they do not work those 3 items could still be the problem.
Here is the light wiring diagram from a previous Post and the Link if it is not all there

I have narrowed mine down to my license plate lights, once they are unplugged, no more blowing fuses. We shall see if it stays but I had no chaffing or anything.
Also according to the manual if fuse 40 is blowing and it's only the rear running lights then it leads to wiring. Wiring can only be the yellow/black as power and black as ground. Broken down into sets, 2 lights per tail and the 2 license lights, those are the only lights in the system that go to fuse 40
This just happen to my stepdad and there is a wire harness under the spare tire. I know this sounds like a pain but it is something under there. Hope you figure it out.
