2014 tail lights
3 Answers
Most likely blown fuse or bad ground I believe tail light fuse is in the interior fuse box which SHOULD be under driver side kick panel. Easiest way is to get a test light start your truck and start testing fuses with the test light until you find the blown one. Good luck
Note the two fuses and park lamp relay, in bcm. Hopefully the bcm is located under passenger side dash. You can see park lamp relay, that isn't serviceable. I agree with my friend, use a test light and check voltage at those fuses in diagram, headlamp switch on. This database I use isn't always correct, but, it's all I have, as far as wiring diagrams. good luck.
Okay passenger side haha wasn't sure but hopefully we've helped good luck friend
