My 2015 Silverado 4x4 WT does not have day time running lights (drl) or auto lights that come on at night. You have to turn the headlamp knob to right to the on position to actually turn the headlights on at night time. I’ve tried turning switch to left over and over to try to turn on auto lights but no luck. This truck used to be a Texas game warden truck if that has to do with it. I don’t know if the feature can be back to normal with bcm programming or an actual wire that goes to headlight or the switch or even the sensor on the dash. I don’t want to forget to turn on the headlights one night and be pulled over. If there is a discussion already over this can you reply with the link please. Thank you.
