SOURCE: 2002 GMC Envoy is having

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.

SOURCE: Need firing order diagram for 2002 gmc envoy

one, five, three, six, two, four

The plastic intake should have this sequence molded into it somewhere, and even the corresponding cylinder numbers in front of their respective holes. Have fun, and thanks for posting on Fixya.com

SOURCE: need fuse box diagram 2002 gmc envoy

If I remember correctly if you look at the back side of the fuse cover, it should tell you what the fuses are. Also in the owners manual in the index, under fuses, it should give you a diagram of the fuse location for the acc. outlets. Good luck. The fuse should be a 20 or 25A fuse.

SOURCE: 2002 gmc envoy shuts off when i turn on the ac whil ideling

If it does it when idling I would suspect an IAC motor (Idle Air Control). If it is opening too slowly the added air the motor needs will not be supplied fast enough and the engine will kill.

It could be other things also but this is where I would start.

02 envoy, 6 cyl, loud wooshing noise when engine is cold. fan clutch seems fully engaged. goes away when engine warms up. is this normal or does fan clutch need replaced


Fan clutches for Envoys and Trailblazer are a problem, they go out all the time.

However, it is normal for it to do this when cold, but will only stay engaged for maybe 15 seconds AFTER you've put it in gear and have started to drive. After this, it will disengage and allow the engine to warm up faster.

If you haven't already replaced the fan clutch once, you're lucky. 2002 is especially bad for the clutches, but all years don't last long. Mine lasted 90k which is pretty long.

Lost my cover that must be removed to drain the oil on my 04 envoy. Any idea of a part number or vendor to help on the web?


Check with Compnine.com, they don't show the cover alone but as part of the entire shield (for 6 cyl), you may have to give them a call.
