DRL not working / All fuses, relays and bulbs good

The bulb holder in the DRL which is L shaped and connects into the harness is probably bad. I had one go bad on me. You can disconnect the holder from the harness via the quick disconnect and use a multimeter to see if you have continuity between the pin and the bulb holder contact. For some reason they break internally and you have to replace the holder.

And yes if you lose a bulb or lose connection in the DRL the cruise control will not work. Not sure why GM does that but all my Chevys lose Cruise control when a bulb is out.

If you say so, ive been working on GM vehicles for 17 years and owned them much longer than that. Not once has my cruise been disabled due to a in-op drl lamp. So I guess US spec trucks with drl defeat or simply not equipped with drl's don't come with cruise?
