#44 of 95 04 Envoy check engine light illuminating by ecolgan Nov 09, 2007 (10:48 am)
My check engine light will not turn off. I heard a sputtering sound twice when i tapped the throttle while in park. Any clue what this could be? I did fill it up with gas today. Ed C.
#45 of 95 Re: 2002 Envoy Stalls when selector switch set to defrost [burnside] by ecolgan Nov 09, 2007 (9:29 pm)
Replying to: burnside (Oct 31, 2006 10:22 am) I have a 2004 Envoy and it has stalled three times when you turn on the a/c, it has done it intermittently since i bought it a month ago. I had an auto Tech. look at it and he thinks it is the Idle sensor. When you turn on your a/c, your Idle sensor is supposed to raise up your rpms slightly to counter the a/c compressors drag on the engine. I noticed that my rpms on my tachometer are at about 600. I also have a 2006 Envoy and the rpms are set at 900. I think the problem is that the Idle sensor is going bad and the idle is set too low. Hope this helps.

Replying to: pcolacchio (Feb 05, 2007 8:24 am) I had a customer with the same complaint a few months ago, and it turned out to be the ground connection behind the right front of the console. There is a big bundle of ground wires held to the body by a 10mm headed bolt, it was finger tight. One of these grounds goes to the shifter lockout mechanism. Also, check all fuses to see if one is bad...there is a fuse center located under the driver side of the rear seat. Hope this helps.

I have a 2003 Envoy and just recently my headlights started to flicker. Then I started having problems with my battery connection, so I replaced the battery and connectors and solved that problem. Now my dash where my heat / ac control is does not light up, blow air, or anything. So now I have no heat and its 20 degrees outside. So I took it into the shop and had them put the computer on it to see what it was. All they can tell me is it's probably the BCM, PCM, or the HVAC. You've gotta to kidding me!!!!!!!!! These are the experts that are being paid 90.00 per hr, and they don't know whats wrong with my car? Instead they would be much happier if I just dumped 2 or 3 thousand dollars into it. Has anyone else had any of these problems and if so what did they do to resolve the issue? Thanks in advance for any input.

The air on my 2002 Envoy SLE will, out of nowhere, just go out. Just as its about to, the temp display begins dropping to where it shows that its 20-something degrees out side. Even when it's "working", it almost never displays an outside temp of more than about 60 deg. The air keeps blowing but its hot air. Also, I'm not sure if this is related or not, but when you turn the defrost on, there's this constant clicking that sometimes stops after a couple of seconds, sometimes until you turn off the defrost. Any thoughts??? Replies to this message: congdonfamily (Dec 13, 2007 2:30 pm)
#49 of 95 Speedometer flaking out by ronm Dec 13, 2007 (1:26 pm)
On my 2003 XL the speedometer hasn't been working consistently for months. Sometimes it stays at zero, other times it gets stuck at a certain speed, or it will move but read low. Dealer says the cars entire instrument panel has to be replaced. Ridiculous to design a car such that all the instruments need to be replaced if just one fails.

Replying to: ronm (Dec 13, 2007 1:26 pm) I had the exact same problem. When I would be going down a residential street at 25mph my speedometer would say I was going 80mph. I took it into a Transmission shop, they put it on a machine, and what was wrong was my speed sensors. You'll have two of them. Its not hard to replace just takes about 45min. I did it myself, but if your not to mechanically enclinded or just don't feel like doing it, I think the shop gave me a price of 210.00..Good luck..

Replying to: pfowler80 (Dec 10, 2007 10:40 am) Just got mine out of the shop. My temperature panel and heat and air both went 100% out. I took it to AMMCO Transmissions. They will look at your car and then tell you what is wrong at no cost. What they do is order the part that they think that it is or the part that their diagnostic machine tells them it is and if it works then great and if not they keep digging until they have answers for you. Mine was the HVAC. DON'T GO TO THE DEALER FOR THIS. The dealer gave me a price of 1245.00, I paid AMMCO 245.00. Goodluck
