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).
Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
Units with 4 wheel disk brakes may develop at situation where the park brake does not hold as it should. Our technicians tell us this can be caused by worn park brake shoes located inside the drum section of the rear brake disks. The worn shoes should be replaced and properly adjusted to correct this issue.
The muffler heat shield may become loose on the muffler causing a rattle or popping noise. Our technicians tell us there is a kit available from GM to correct this problem.

2002 GMC Sierra 2500 HD Reviews
I started to here a pulsation noise behind my glove box area about every 30 seconds. With my hand I reached under and located the noise against the fire wall. I found a damper that was opening and closing back and fourth. Then found out I have a cabin air filter; changed them out with new ones. Thought that would be the problem, but I still have this damper wanting to pulse back and fourth from open to close. I pushed the damper with my hand a few times but it still wants to go from open to close. Is this some sort of a vacuum problem or maybe an electrical signal telling this damper to go back and fourth? I think this is a damper to bring in outside air into the truck cabin.
