The headlights on the envoy are the easiest parts of the car to repair. You just pull the two tabs at the top of the headlights, screw out the bulb containers and you are good to go

SOURCE: GMC Envoy w/ code P0128

Start at $89 right off the bat just for diagnostics and then depending on what they find that is causing that fault, at LEAST one hour labor, plus parts....I would say $250 is a good ballpark figure....looking up your fault code now.

2003 GMC Envoy Heater Fan doesn't always blow


Your problem most likely is the resistor block. In order to limit the fan speed a reistor is placed in the circuit which will limit current flow to the motor thus giving you the diferent speeds. High speed bypasse the resistor to get full motor speed. Since you only get high speed it is very likely that the resistor block is faulty

2003 gmc envoy cold start


If you live in a very cold region of the world like I do and own a GMC Envoy you will know these vehicles are awful in cold temperatures (-30C and colder). Every winter the vehicle refuses to start, the reduced engine power light turns on and a GMC mechanic gives me a bs excuse for why its not starting. The simple answer is that this vehicle is awful in the cold. When this happens and hopefully it happens at home, I have to get my forced air kerosene heater out,put it under the engine bay of the Envoy, open the hood and tent it with a tarp and let the engine "thaw-out" for about 2 hours, you can also put the vehicle in a heated garage but that takes about 8 hours to thaw that way. There is NO OTHER way to fix this problem. I emailed GM about the problem and their only response was to ask for the VIN number and the name of the 'GM certified' mechanic I was taking the vehicle to. All a load of bs from GM....they know this is a problem and won't do anything to help fix it. My next vehicle will not be a GM while I live in the North

2002 GMC Envoy is having a tough time shifting at 85,000 miles. It also starts & idles at higher RPMs. The car is also much noiser from the engin & fan. What is wrong - the trans., motor needing a...


I ran into this concern with my 2002 and my wife ran into the almost identical problem with her 2003. this may sound silly,, but it was the clutch fan. Extreme loss of power from time to time came first. Then a roar of the what seemed like the engine when stopping. Actually cut off after it started to roar at highway speeds, and had absolutely no excelleration from time to time. Sometimes all of the symptoms completely went away. After taking mine to the dealer several times, finally they got it right and replaced the fan clutch. When my wifes 2003 SLt started doing the exact same thing as my 2002 had done, we both knew what the problem was, and the dealer did a quick fix. $600.00. Perhaps this should have been a recall feature, but never was. Everyone that I know that has an envoy, somewhere around the 72,000 and 103,000 mile mark has had this problem and have had to have the clutch fan replaced. It may sound like the vehicle is going to have to be junked,, but that is all it needs.
