Me too !!!!
Hi. My name is Thomas and I have a 2016 Silverado LT Z71. I'm the original owner so I am aware of what the truck has been through and that is nothing that can explain why one day the HID headlights shut down and just regular old headlights now, fog lights stopped working, the horn, some trailer lights, the backup camera didn't work, then worked here and there and one day just began working again, plus there's a few other electrical issues too. I've been tracing them with Foxwell Diagnostic Scan Tool that has the complete Chevrolet software but I'm only an amateur tech and haven't had much luck and that I did is beyond my capability. Have you had any luck with your problem Tony? I know that many times problems are similar and pervasive but can be solved by word of mouth. I noticed, if I read it correctly they this post is from 2017 and see that
several people responded which I'll read up on. Thanks Tony
