I currently have a 16 ltz z71. I recently noticed that the fog lights come on when starting and flicker. I know that they shouldn’t be coming on unless you hit the switch but mine come on at ignition. They even come on with both the headlight and fog light switch off. I also recently bought and installed a new oem fog light to replace the last one that had a crack. Is it possible there is a short in the new one causing this issue or could it be a bad control switch?? In need of some help. I cant figure out the issue.
