No Driver Turn or Stop Lights on Trailer with 2015 Ram 3500 Tow Vehicle

Question:

I have No driver side turn signal or brake lamp function, I have verified that the trailer lights are all functioning as they should using a friends vehicle. When the trailer is connected to my truck I have all other light functions, all of the running lamps work as well as both tail lamps work, but no brake, turn, or emergency flasher function on the drivers side

It sounds like the left stop/turn signal fuse is out on your 2015 Ram 3500. In order to check this you will want to pop the hood, find the power distribution center (PDC), and locate the yellow 20 amp F53 fuse which is labeled, "Trailer Tow – Left Turn/Stop Lights". If the fuse is bad then replace it but otherwise you have a wiring issue or error with the body control module (BCM) and you will need to take your truck to a repair center for service.
