I have a 2024 GMC Sierra 3500 Denali. When pulling my fifth wheel, the auto lights come on and the trailer running lights stop working. I have had the trailer checked multiple times- a short was found in the box once, but even after fixing the short, the lights worked fine until the auto lights kicked on and it stopped working again. The trailer works with an older truck. I have replaced all trailer related fuses and I’m wondering if the new truck is just so smart it is shutting those down because they pull a little too much amperage. Anyone else have this specific problem?
