It was the oddest thing, it worked fine up until the other day. I pulled a trailer in the morning, disconnected it, hooked another trailer that afternoon and no lights. Now doesn't work with any of my trailers. All trailers I have pulled with it before. It is suppling the hot power, just nothing to the lights, nor does it sense the trailers when plugged in. We checked connections and fuses, and also verified that the trailer lights worked on a test stand. Just background information, I own a trucking company so had my techs go all through this and they can't find any disconnects.

When I connect to any trailer, my truck won't sense a connection and provide power to the trailer plugs for lights to the trailers. This is with both bumper pull connection and inbox fifth wheel connection. This has been consistent with any trailer I try to hook up. This happened all of a sudden with no issues. It is a 2023 Silverado High Country.
