thanks I will have to tell him to look for a relay(s)I don't know about a 2000 model GMT800 but I can tell you on our 2006's pulling the DRL relay in the underhood convenience center stopped the DRL's, no problem. Ours have been disabled for many years. The 800's use a high wattage bulb next to the turn signal, instead of burning the low beam headlight at a lower voltage.. and for some reason those bulbs seem to burn out quickly. I got tired of messing with them so I just pulled the relays.
