The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 2001-2003 models is #4114K (trade number).

Day time running lights on most all GMC and Chev product burn out
DRL bulb burns out frequently
typical gmc, seems all gmc running lights go out on a regular basis, try the installing the longer life bulbs that have a better filiment in them..
