Searched a ton of forums with this issue and I’ve seen One post that tied all my problems together and thought this would help. Bought my 2016 Sierra 3500 duramax used with 90k miles. Off the lot I had the blue screen of death. Along with my trailer brake cutting in and out when pulling. Changed out the camera and still nothing. Went over all the fuses at least 3 times and still nothing, until I pulled the fuse for my trailer brake ( under hood) and noticed a very small patch of white corrosion forming?. I eventually lost my backup lights sometime later. Searched some posts and another guy with the same problem mentioned he changed out his main fuse block under the hood and it fixed the camera. I order a new fuse block and for the first time I got my backup camera back and my backup lights are now working. Hope this helps
