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: My 2002 GMC Envoy is stuck in the neutral position

i would try to get down to the linkage adjustment and see if maybe it is not adjusted properly or if it jumped out of alignment. Place the transmission in park and the selector in park after loosening nut and then tighten down the nut.

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.

How do you reset the idle on my gmc envoy. had to disconnect battery and now the idle is not correct.


After disconnecting the batter (which clears the computer), you need to drive the vehicle at a steady speed around 40 mph for 5-10 minutes for everything to readjust.

Hope this helps.

My Envoy will not stay in two-wheel drive mode (it shifts to neutral while I'm driving). When I use AWD, it rides very rough, particularly during tight turns. cjccbay1@msn.com


check tires are matching and air level correct but sounds like problem in drive train possible problem with a bad front c-v joint/ trans-axle or fault with actuator at trans check wiring and actuator mounting

Try disconnecting the battery for a few minutes, that might get you out of trouble for now. There are some common problems with these 4wd systems. Most common is the mode position sensor on the encoder motor. Sometimes it can be the switch on the dash. Fact of the matter is I can't tell you what is wrong without using a scantool to retrieve the fault codes from the computer controlling the 4wd.

Wont shift back from 4x4 low, to 2x2


I also have a 2002 Envoy. Shifting to and from 4wh and 4wa can be done on the fly but shifting to 4wL has to be done stoped and while in neutral. Try that. Otherwise I'm afraid its a new computer for you. Its located under the left rear seat and you need a loan for one.
