Troubleshooting A 2017 Ram 2500 That's Sending Constant Power To The Trailer Running Light Circuit
Updated 04/15/2024 | Published 04/13/2024
Question:
The pin on my 2500 2017 Ram that supplies power from the 29 fuse to my towing parking lights is always hot. My trailer running lights are always on when the trailer is plugged into the truck. If if pull the 29 fuse, the lights go off. I suspect a stuck tow parking light relay but I cannot find it, any ideas?

Hey Karl,
The trailer running lights shouldn't be receiving power unless the running lights in the Ram are on. I'd doublecheck the wiring for the vehicle's running lights to see if power is somehow getting sent to the trailer running lights. You could have a short or knick in the wiring somewhere and it's touching the wire to provides power to the trailer running light fuse, causing the constant power to the trailer running lights.
