Speedometer or Other Instrument Panel Gauge May Work Erratically
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.
Daytime Running Lights Are Prone to Burning Out
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).
Parking Brake Does Not Hold Due to Worn Parking Brake Shoes
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.
Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator
One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.
Popping Noise From Muffler Heat Shield
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.

GMC Sierra 2500 HD Stories
Hello my truck runs great but the A/C / Heat control only works on HIGH!! I think I'm going to change out the control unit . How does that sound??? THANKS!! Oh also the turn signals ,when activated left/ right set the hazards off?!?! Spooky
i currently have my 2003 gmc sierra 2500 in the repair shop at a local gm dealer. it has been there over a week and they cannot figure out what is wrong with it. The range shift inhibitor light came on the dash board so they replace the transfer case for $2100 and the light is still on and they cannot figure out why. They said the gears were wore out in the 4 wheel drive but i find that hard to believe as it only has 83000 miles and i never used it for heavy duty 4wheel driving just occasional driving on snow roads and driveways nothing major. If you can figure out what is wrong would greatly appreciate any ideas as the dealer cannot seem to figure it out. I would like my truck back without a larger bill already bad enough. thanks for any help
After buying a new 26' travel trailer we decided to trade in the 2002 1/2 ton Sierra and get a brand new 2006 Sierra HD 2500 SLT 4x4 with the 6.6 Duramax Diesel,6 speed Allison and went crew cab this time. What a difference that made in pulling the trailer. I can go from Phoenix to Flagstaff with the cruise control on pulling the trailer holding 65 mph (as long as I have an open lane). I had test driven the Ford Super Duty and the Dodge before I bought this GMC. At the time the GMC had the most horsepower and torque 360/650. I liked the cab space of the Ford but that was it. The Dodge seemed to plasticky and plain even in loaded form, even though it had lots of storage cubbies and stuff. So since I had a GMC before I went with it again. I have replaced the 2 batteries twice (batteries don't last long in AZ) and tires 3 times. The factory tires and rims on these HD's are ugly and skinny, it makes the truck look like Grand Dad's, so I put on 18" Moto metal rims and some nice BFG All Terrain T/A K/O 285/65/18 tires, with some Westin nerf bars, a Rhino liner and a Lund bug shield and added an AIRRAID intake. I also tweaked the torsion bars on the front suspension so the truck looks level instead of dipping down in the front. That may have cost me some gas mileage because that truck has never seen anything better than 18 mpg and that was unloaded, downhill, with a tailwind. It does get better city mpg than my 5.3L '02 did. I get about 14 mpg, if I'm easy on it. When I pull my trailer though it's 9 or 10. These other people I talk to with the same truck that tell me they get 14-15 mpg pulling a trailer are full of it. My best has been 10 mpg maybe. Problem wise, I had to replace both wheel bearings at 75k miles (I have 84k on it currently), the a/c quit of course right when it was 112 outside, turns out it was the climate control box (dual control) some part went out in that. Had to have a steering box and p/s hoses replaced under warranty, otherwise that was it. The light bulbs are out on some of the steering wheel controls and the radio knobs all of the words are rubbed off. It has the Bose stereo and DVD player (which I play my Ipod through since there is no jack on the radio for an ipod)but today I tried a CD and they spit right back out. Probably because in 6 years I hardly played CD's, just mostly XM and my ipod. Otherwise the engine and trans are great and I've had no other problems. If you follow the scheduled maintenance, these trucks last a long time. I still have the original brakes and they still have 50% life in them (even after pulling a camper for 6 years). I don't like the '07 & newer ones. Less chrome and they have more emission control junk (cat box) and you have to pour stuff in the gas tank on occasion. Interiors are nicer though, but I don't want to shell out $50k again for a truck.
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.
I bought june 2006 from now defunct dealer lawrence marshall. I drove it over every bumpy road i could find and didn't rattle at all. In september the doors started rattleing and the seats squeaking and noise from dash.The doors the worst,it make a noisy clacking and bumping every start and stop and on bumpy roads,they were able to fix only the seats . April of 2011 the dash stated making a steady bumping noise,internet research says it is A/C actuators.So at 45,000 milesit rattles like a 10 year old junker and i guess the A/C will fail whenever..Oh yeah,,the tail light assembly fell out of the left side in august 06 and the right one fell out sept 09,,only vehicle i have ever owned in 50 years that tail light fell out of voluntarily....ha!!
