2000 Chevrolet Silverado 1500 LT 8 Cyl 5.3L
Body & Interior
will switch from driving lights to headlights after a couple of minutes of vehicle being on, no matter how bright it is
the daylight sensor could be acting up or could be covered, I believe chevy put it right on the dash near the base of the windshield will look like a little dome. make sure your not covering it with something and that its not damaged.
