I would like to see if they're in a code to have my fog lights automatically turn on and always run when my headlights come on or off. I changed from "cornering" to only "fog" using the forscan and not turning off when the brights come on.
Something this truck does that my previous GM didn't do is, if I had the fogs on when I shut the truck off, they seem to still be on when I turn it on again.
My fogs stay on with the headlights if I leave it on Auto. If you turn the headlights switch to the off position and back on, you will have to press the fog light button again to turn them back on
