Where do I find the sensor that that controls the daytime running lights and automatically turns the headlights on and off?

You my be refering to what gm calls a sun load sensor. It is on the dash top panel. It may be blocked or bad Or dirty. Part number 13498958.. Let us know if that was it and if it repaired the issue

Yep, that was it. For some reason when the thing is registering direct light, one of my headlights went work and I was failing inspection. But I drive the car at night, and I know both lights work. So I covered the sensor, started the car and both lights came on. Inspection passed
