#3 of 67 Re: GMC Envoy: Problems & Solutions [tidester] by afforte Sep 08, 2006 (10:24 am)
Replying to: tidester (Aug 09, 2006 9:42 pm) my 2002 Envoy xl, windshield wipers will not turn off. When the problem first started, if I turned the wipers off, then the engine, after cooling down, the wipers will go off, once the car is restarted. Now they won't go off at all. Where is the wiper fuse? Is there a relay problem. Can the wipers be disconnected, until needed? Any recalls? Thanks, AFF Replies to this message: gmcnightmare (Jun 22, 2007 3:18 pm)

#5 of 67 Envoy Throttle Body by stringmusic1 Oct 14, 2006 (12:13 pm)
I have a 2002 Envoy XL. The engine light came on and the engine began to miss badly. I had my buddy who is a decent "old school" mechanic take a look at it. He ran a diagnostic test on it and it show that "cyclinder 1 was misfiring". He suggested I take it up to Advance Auto and get their free diagnostic to confirm. I did and got the same diagnosis. So my buddy took it apart at the coils and said they were all firing but he demonstrated to me that the throttle body was not opening when you gave it gas. He said I probably would need a new motor for the throttle body but that there was some electrical signals that might send a message to the throttle body not to open such as the drive train, etc. Can you help me with this? Thanks in advance. Replies to this message: 02envoylover (Jan 04, 2007 10:39 am)

#7 of 67 CD Player by galwaygirl Oct 28, 2006 (5:43 am)
Our 2002 Envoy will constantly look for a CD to be in the CD player. If we take the cd out and listen to the radio, it will make this whining sound, and sometimes interfere with thr radio. As long as we leave a cd in the player all the time, its fine. Has anyone else seen this?
#8 of 67 2002 Envoy Stalls when selector switch set to defrost by burnside Oct 31, 2006 (11:22 am)
When I put the climate control selector (floor, panel, mix, floor+defrost, defrost) to defrost, the engine RPM goes down for a second then back to normal. This repeats until the engine stalls. This also happens when the AC is turned on. I suspect a vacuum leak but have been told it may be the AC unit itself.   Has anyone had experience with this issue?

#10 of 67 transfer case control module by carsinvt Dec 14, 2006 (7:04 am)
I have a 2002 ENVOY with a "service 4 wheel drive" light illuminated. Dealer said it indicates a transfer case control module issue. I checked the switches actual connections. Now.. I want to locate it physically to replace it. (additional note: I just had that same issue with a 2000 Chev Silverado.) I have "keyworded" every aspect of the phrase to try to get help. All I get are OEM parts locators, it seems. Can someone lead me to a chassis electrical (brakedown) site/link? Or better yet tell me of it's location.
#11 of 67 Rattling Brake by gujushah Dec 15, 2006 (11:33 am)
I have a 05 Envoy XL. I just got it 3 months ago...with about 7000 miles on it. The brakes kind of rattle when i press them...IF i am on the highway and suddenly traffic comes up and i got from like 80 to 30 within 500 ft, the brakes rattle. no noise, just slight shaking...of the brake pedal..Any idea why...
#12 of 67 Stereo Aux In? by jmatthew3865 Dec 27, 2006 (7:06 pm)
I have an 05 Envoy SLE with a stock Delphi Single CD Stereo. I've recently yanked the stereo in hopes of finding out if i can plug a cable directly into the Aux In connections so that I can pump my sirius signal directly to the stereo rather than rely on the FM transmitter (bad reception). After getting the stereo out I've, of course, noticed that there are only the two proprietary bundles going into the back of the stereo as well as the antennae cable and a white plug. (I'm not sure what the white plug is or what it would be used for)   so I'm wondering if anyone has had any experience with, or accomplished what I'm trying to do here.   I've also tried the Sirius FM relay kit, but the antennae cable in the back of the stereo doesn't seem to be removable.   Any help is appreciated.
