I have a 2019 chevy silverado LTZ and having the same issues. Taken to 2 different dealerships and all they found was a blown 30 Amp fuse. Something is making it blow. 2nd dealership had my trailer with the truck for a week and couldn't figure it out. After I brought it home, no lights on trailer, a friend tested my plug on my truck and the neg pin was showing a positive charge he reset it and it showed just a negative. All the lights worked on the trailer then. 2 weeks later I hook up trailer and freaking nothing. Trailer works fine on other vehicles so it's not the trailer. Anything I hook to it I get same results. I'm ready to take it back to the dealership.
