I have a 2004 & 2008 GMC Envoy 5.3 ltr. This video is so DEAD ON TARGET with the issues. So far currently 147, 000 mile range but also near the 15-20 year mark on my Envoys these issues have arose already. The front hub assembly’s BOTH the sensors and the alternator. But if it hadn’t been for this video I’d of never known about the sensor with the steering position. That’s my issue in my 04 currently. The other is my ABS light in both envoys. Wish I could figure out that one. Thank you 1A Auto for your videos and you GREAT PRICES , Parts and Customer service . Most of all your time in making these videos because you put repairs in a simple and easy to understand laymen terms for us DIY mechanic’s.
I've had my '05 since new. In 144,000 miles, I've done brake pads (still on original rotors but got custom made braided hoses), suspension bushings (ball joints and struts/shocks on the rear while I'm at it), spark plugs (ignition coil boots, oxygen sensors and injectors cleaned on ASNU machine with new Viton seals and stainless basket filters since I'm in there) a radiator and a water pump. Electronics wise, I've replaced the rear CHMSL but that's been it. I've also been on top of all oil and fluid changes every 25,000 miles (engine oil by the OLM). This has been a pretty reliable vehicle as far as I'm concerned, even with the dreaded 4L60E that I've run nothing but TES-295 in since day one.
I have a 2006 GMC envoy slt. I have 215,000+ miles on it. I love mine. I put some work into it but I'm content with it. This vehicle helped me a lot. It was well appreciated. Keep it up.👍🙂
I have an 08 Envoy SLT, the Ignition issue is for every envoy, even the GMC Jimmy's. The other issues that envoys have is they tend to get electrical shorts. They also get secondary intake issues and evap leak issues.
I have a '05 Envoy SLT since 2006, got it at 19k miles and now has 166k. The video on the window regulator was very helpful and I ordered the part from your company. This Envoy has several problems but I want to fix it up. My kids grew up with this car and I don't want to give up on it. Problems: stalling/hesitation, speedometer and fuel gauges out, A/C intermittent, radio static, and needs a body panel replaced or repaired. Just replaced a window regulator and already had to replace the little plastic connectors on each end of the transmission shift selector cable. It's had not one but TWO water pumps replaced and had to get towed each time. But that was years ago. I want it to keep going!
Just hit 250K last week on my 04 Envoy, and she runs beautifully so far. *fingers crossed* I had the ignition switch, camshaft sensor, water pump, front struts, and rotors replaced so far. Hopefully, she stills holds me over for a bit longer.
One thing I didn't see was the factory power steering cooler. I am up in Canada and have owned 3, 2 Envoy 4.2L and 1 Saab 6.0L, and all three had the same part rusted out about the same age (6 years old) even with annual rust protection oil spray. Out of the blue the power steering pump will make noise and when you check it there is no fluid. New replacements are much better quality and thankfully have never needed replacement again. I still have 1 Envoy and know where the 2004 is, both running great with 250K + , my 2006 besides brakes and tires has pretty much original everything under the hood, except Power steering cooler, power steering lines and 3 sets of wheel bearings, 1 due to stabilitrac errors and I did have a weird one where the truck would stall every time you put on the left turn signal. A bad ground connection on the firewall caused this by the fuel pump and turning signal shared the same one. The other 4 issues you mention have not been a problem yet... I am likely on borrowed time but this truck has been amazing and very reliable really.
I have 2 other issues. 1 when the water pump starts to go bad. The fan starts to wiggle and eats the shroud. 2. The backing plates rust out way too early. This holds your parking break brackets.
275,000 on my 2006 Envoy. It’s not in great shape , but it still runs good ! What I’m dealing with now is the ignition getting stuck in the middle when I turn off the key…
subsscribed. I have a 2005 GMC Envoy at 120k miles. He's getting up there, his name is Charles. I'm hoping to maintain this vehicle and get many more miles out of him.. Thank you for this video. Looking forward to checking out the other one and getting some parts down the road. Literally... L.O.L.
I own one with 137,000 mile I bought it with 93,000. I have had to replace all wheel bearings. I am currently have to replace bearings in the front differential. I still like the vehicle. Michelin tires work best for me.
Great video , actually all your videos are very informative and help me through issues on my GMC which I love, but these newer cars ,they keep you on your toes if you are an oldster and your videos are great help.Keep up the good work.
I replaced my alternator a few weeks ago because it was clicking. Still able to start though. I took it to auto zone and they said the alternator failed the voltage test. So it may have been draining my battery Faster than normal
I had the same problem. I ran a battery terminal wire from my negative post on the battery to the inside of my dash, put an electrical shut off they run in race cars and ran the other wire to the negative wire that originally hooked to the battery. I turn it off every night after I lock my doors…
Had the same problem as well and in my case it was the instrument cluster. I went through that sucker trying to figure it out. After what felt like a lifetime checking with a volt meter it ended up being the cluster. Replaced cluster all was fixed.

They should add a disclaimer, the first 2 items only apply to the 4.2 I6 engine, they don't apply to the 5.3 V8. #3 only applies to vehicles that have traction control systems, and equipped, which was a 2005-09 thing only. The last 2 items apply to all years and models. I would only add the 5.3 V8 AFM/DOD systems are problematic, and only apply to the 2005-09 model years.
👌 Best video by far for my GMC Envoy 07. Every-single-one you mentioned I had fixed or I'm currently fixing again. I swear I have watched soooo many RUclips videos about this car I feel as if I specialize in Envoys. Anyways... Can you do a video on on the Throttle sensor unit? This seems to be a big problem for us envoy drivers. That and the door actuator needing replacement due to the air and heat not coming from the front facing vents. And recalls on this car.... SO many recalls. One due to the driver door getting too hot and fires have been reported in the past. My door gets real hot itself even after I brought it in for one of the many recalls. But... I definitely need a video on how to clean the throttle and/or replace. That's my current reading on my check engine light. I also carry my jump box with me because my car won't start probably 3x a week. Ugh.
2007 envoy 110k miles.. Let me start with i love this car. Ive owned several diff cars and it runs great. I have also replaced the ignition switch 3 times in the 8 years owning it. May have to do it a 4th..its a pain.. But i love this car and for something that runs great.. Safe in missouri winters and paid off ill take it as a small annoyance.
Been having problems with my 2005 GMC Envoy XUV sle, it has 394,000 miles and still runs strong... amazing vehicle. The problem I've been having lately, is an occasional dead battery and all the gouges drop to zero and the battery warning light comes on. After a minute or so, sometime less, all the guages return to operating normal. Checked the battery, alternator, and even added an extra ground wire from the motor to the body. Recently, I was told that it could be the ignition switch. Has anyone else encountered this problem?
It is possible. However Ive also seen the cluster be the issue itself with parasitic draws. Had to replace one and also decided to add a extra ground from the cluster to the body in case if the original ground in the wire harness might be the issue and not have to tear it apart again.
Yes bout a month ago n it was very strange. Right after this I totalled it. I hit a patch of ice n went over a bank n couldn't get out. I loved it n I actually want another one bit idk now. I'm just glad I didn't get hurt or worse . Ty
I recently bought a 05 xuv envoy. Came with a non functioning fuel gauge and light stays on. I've only put 5,000 miles on it so far. Bought it at 67,300k Miles. You got 300,000k+ out of it. That makes me feel stoked on my purchase
My envoy has 225,000 miles, suspension needs rebuilt but engine itself is perfect! Not a lick ot dirt on throttle body, still gets advertised mpg or better 20 years later
The actual problem that ate my head was the *gearbox*. Renewed it twice, again the next year it will end up with transmission issues that need another renewal. Fixed it and sold it.
My 2002 4.2 has 251k miles and i finally had to put an alternator in it two weeks ago and a water pump this week. Other than wear items I've never put a dollar into mine in years.
Great Share i have,2003 Envoy giving me grief now 🤣. Just did,spark plugs and Valve cover gasket leaking and oil is hitting Spark plugs. That's an Expensive bill,$ 700.00 in Canada. Trying to do kt, before Winter. Txs for this,Video and all your others. I try to do as much,of my own Vehicle Maintenance but it is getting done at a Shop. Im a Gal that is Thankful for many of your Videos on vehicles I've owned👍. Saved me $ on things,I can do Myself.
The next time my thermostat goes bad in my Envoy, I'm gonna take the guts out of it, reinstall the housing, bypassing it, then I'll install an inline thermostat down where the lower hose goes into the radiator. They unscrews easy and use standard thermostats , so you can pop out the thermostat when you flush your coolant without impediment to the water flow.
Man some of the problems you guys are naming I've never ever dreamt of in my Envoy! Heating door issue what the heck is that??Over 276,000 miles & still running strong, except a cam position sensor code and upper intake gasket leak other than that she's great! I have a 2003 Envoy XLT with the 4.2ltr inline 6 with all the bells & whistles except sunroof! I love this thing and wish GM would bring it back with modern styling better interior materials and better gas mileage! I'm about to purchase a 2005 Denali XLT AWD for $300 needs engine and transmission but the body and interior are in great great condition compared to mine! I have a personal mechanic that can do the work very reasonable for me but I'm wondering about the reliability of the 5.3v8 heard they have lifter issues due to the cylinder deactivation process GM used. Is this a good buy for $300 also I can get the motor & trans for a discount because of my mechanic!!
You forgot the cracked exhaust manifold issue the ac condenser drips right on it if the tube isnt on or the shield isn't on the manifold allowing water to splash up at it and the insterment clusters go funky 4x4 actuator like to bust apart without warning and the fuel filter being in the tank! Big issue i own a 05 and the sending unit was from the xl
I got a 2004 xuv 6 banger and my fuel filter is right on the side of the tank easy breezy. But the fuel filler neck attachment on the tank tends to crack
Great vid on a pretty great (but not perfect) vehicle. I have an 03 Envoy XL SLT with the excellent 5.3 V8. 245k miles, gobs of power with my 4.10 axle option, and relatively good mileage for a heavy V8 beast. Have had ignition key issues (wouldn't shut ignition off and release the key), Front wheelhub bearings, and replaced most of the worn out steering/suspension. There's also a battery draw, could possibly be stereo/alarm system (I just pulled fuse), OnStar system (pulled fuse), short in driver side door (nothing electrical in door works except power locks, sometimes seat heaters come on randomly), and likely frayed/grounded wires in the troublesome XL hatchback. 4X4 isn't working, and there's a loud knocking under dash related to Automatic Climate control upon starting vehic. Other than buying someone else's electrical gremlins and uninspiring soccermom-mobile handling, I love it, particularly the modified LS engine.
Your supposed to drive all GM 4 speed transmissions in 3rd gear until above 80km/hr then put into overdrive(obviously a lower RPM gear) have driven GM's for many years and haven't had to rebuild a trans yet *touch wood*
My truck is back! Right on. Would you consider doing a video on replacing the push button for the rear glass release? Hoping you also sell that part. Thank you! Love your videos.
My GMC Envoy starts up in the morning and turns off within seconds many times. only when it's cold. almost an hour to turn on properly. After it turns on everything works perfectly the rest of the day.
Hi, I have a 2002 GMC Envoy. Today I just left work and it's accelerating all by itself to almost 2000 rpm. What do you think is wrong with it? It has almost 250,000 in it. Thank's in advance! Great videos!
+JR0CK Chillin We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I have asked so many on these videos about a problem I'm having with my 2002 envoy and can't get a direct answer to my question maybe it's because no one has had the same exact problem. But I'm trying one more time. My 2002 Envoy has a little over 200,000 on it and until February of this year it has a been a great vehicle. But one day I was driving down the road at 55 mph and all of a sudden it was like I had no gas. At first it sputtered like it was running out but the gas needle said it had 1/4 tank and I knew it was not out. But I pulled over and sat there for about 10 minutes and turned the key and it cranked up instantly. I drive it about 5 miles and it happened again and I pulled over and shut it off. It would coast idle for several miles but when I pushed the pedal it got no gas. This happened 4 times until I made it home. The check engine light never came on. The next time I drove it was after the fuel filter had been replaced. It did the same thing after I drove it for 5 to 10 miles. The last time it was test driven the check engine light did come on and it said shut engine off. This had never happened before. My mechanic friend came and picked up and had it for a few weeks. The next time we test drove it it went further before it happened. It went 25 miles and this time it coasted for a mile and when the gas pedal was pushed it picked back up and it was driven another mile to his house. It has had several diagnostic tools hooked up to it but it doesn't show any codes. I replaced the battery as well as the fuel filter. But we don't know what else to do without taking it to a shop that has access to gm diagnostic app. I've seen so many videos and stories where people were advised by mechanics to replace fuel pump and after they spent a thousand dollars doing that they found out it was not the problem and instead was a sensor or some other less expensive part. Does anyone know anything about this or what it might be?
Ignition switch on my envoy caused "reduced engine power " and gave a code pointing to the throttle body. Wasn't the throttle body, it was the ignition switch getting or not reading the correct voltage.
I just got that "reduced engine power" light on my dash recently during a -20 cold snap. Couldn't keep the engine running and wouldn't go above 30mph. Pulled over and let vehicle sit for like 10 minutes, started, drove away like nothing had ever happened. Had no clue it was possibly ignition switch until now. TY!
Bruh I have a 2003 Envoy SLE with 254k miles, the only one of these issues I've ever had was the heating one, the thermostat is alright. The groaning noise actually happened once, but if you get your tires realigned it usually goes away.
Themostat was the first to play out when he got the truck . He gotten it fix bout a month ago and now it saying the cooling fan sensor going bad . The engine light came on after we use the air in the truck .
Your videos are very helpful! Can you please do one on how to replace a mode actuator on a 2006 Envoy Denali? I have air coming out of the floor and defrost vents, but not the front vents. I have located the non-working mode actuator, but I cannot figure out how to get it out to replace it.
Fuel vent issue will it leak gas? Cause I get lousy milage and I swear when I turn sharp the gas gauge drops. But I don't see any leaks or wet spot on the ground or clean under body parts where gas might of touched. Thanks
About to get a 2004 GMC Envoy like this one with 5.3L V8...Do You carry the New starters for it? If Not, what Part # do I need? I can only find the V6 ones. Thanks !
Could you plz tell me what fuse operates the license plate lights on an 2005 GMC Envoy??? Plz, I've been looking at my book & I can't seem to find it, I need help.
question: I have a 2006 GMC envoy SLT (3rd row seating) and the check engine light is on, I think it came on because of a damaged gas cap, is that possible?
I think my ignition switch is bad on my 03. It has 102k, on my odometer. When I put the key in it won't turn over and the driver seats starts adjusting itself instead of turning over. (I got my foot on the brake while trying to turnover) I have gotten it to turn over only a few times, it runs great other than that.
My 2005 gmc envoy 110,000 had a missfire I bought 6new spark plugs started running a little better except the coils were bad so I went to go buy 2 coils as I was changing them with the car on the car turned off. Had to have the car towed and now it’s cranking but won’t start. Anybody have any idea?
clean the main wires going into the fuse bank and take the fuses out and clean them. Fixed my issue. The main wires had some minor corrosion and the fuses just had a bad connection.
I replaced my ignition switch myself after countless efforts to figure out what was wrong (replaced alternator battery etc thought it was a wiring issue) eventually got to ignition switch and when I took the old ignition switch off which was clearly the one that the manufacturer had put in the car because of the way it was zip tied into all of the other elements when I took it out I noticed that one of the metal prongs that was supposed to be inserted into the switch or whatever was completely bent down flush so it had never been completely plugged in or connected in general and it was just probably catching friction which was pretty frustrating because it was a big issue I had for a long time and I couldn't figure out what it was and to know that it was from the freaking manufacturers installing it incorrectly was pretty I can't even think of a word dumb basically lol
Dear 1A Auto, I have gmc envoy 2007 when I tern steering while drive sloly I feel the car like jumping on humbs. I went under the car I fond cracks on the rubber of the both racks and there is a red oil on the gear case. Can you plz tell what the problem is and how to solve it. Thx
Wow. I have an 03 envoy xl for a decade and none of these issues! Drive it daily to work and back and it runs better than any car I have. Only problem I have is I left my driver side window down during a rain storm and now my entire control panel is out. Cant roll up windows or lock doors from the control panel. Obv I rolled up the back windows using those switches but now my drivers side window wont roll up and its 20 degrees! Uhh

I have an 06 GMC Envoy XL 4.2L and when it is cold out it dies meaning when I turn it over it starts but then dies if you leave it for a couple minutes and try again it is fine but it only does it when it's cold. Any ideas?

The predecessor to the Acadia. My Acadia was 8 years old and the only thing that stopped it was hurricane Ian. I miss that SUV.
No one mentioned the rear air suspension going out and how expensive it is. They actually sell the kits to switch your air shocks to springs

There is a significantly large yet unrecognized gmt360 (TB,Envoy) following. We need more of this lol

Thinking about buying a 05 Denali envoy with about 145k mi for about $5k for a point A to B car. Think it would be a decent deal?
Been having problems with my 2005 GMC Envoy XUV sle, it has 394,000 miles and still runs strong... amazing vehicle.
The problem I've been having lately, is an occasional dead battery and all the gouges drop to zero and the battery warning light comes on. After a minute or so, sometime less, all the guages return to operating normal. Checked the battery, alternator, and even added an extra ground wire from the motor to the body.
Recently, I was told that it could be the ignition switch.
Has anyone else encountered this problem?
It is possible. However Ive also seen the cluster be the issue itself with parasitic draws. Had to replace one and also decided to add a extra ground from the cluster to the body in case if the original ground in the wire harness might be the issue and not have to tear it apart again.
Yes bout a month ago n it was very strange. Right after this I totalled it. I hit a patch of ice n went over a bank n couldn't get out. I loved it n I actually want another one bit idk now. I'm just glad I didn't get hurt or worse . Ty
Yes I have a 2004 gmc envoy slt that does that
Nice! mine has 254,000 miles, I hope to get it to 300,000
I recently bought a 05 xuv envoy. Came with a non functioning fuel gauge and light stays on. I've only put 5,000 miles on it so far. Bought it at 67,300k Miles. You got 300,000k+ out of it. That makes me feel stoked on my purchase
My envoy has 225,000 miles, suspension needs rebuilt but engine itself is perfect! Not a lick ot dirt on throttle body, still gets advertised mpg or better 20 years later
The actual problem that ate my head was the *gearbox*.
Renewed it twice, again the next year it will end up with transmission issues that need another renewal. Fixed it and sold it.
What head? Engine head???
And you are predicting trans problenms? Or are u saying it already happened???
My 2002 4.2 has 251k miles and i finally had to put an alternator in it two weeks ago and a water pump this week. Other than wear items I've never put a dollar into mine in years.
Great Share i have,2003 Envoy giving me grief now 🤣. Just did,spark plugs and Valve cover gasket leaking and oil is hitting Spark plugs. That's an Expensive bill,$ 700.00 in Canada. Trying to do kt, before Winter. Txs for this,Video and all your others. I try to do as much,of my own Vehicle Maintenance but it is getting done at a Shop.
Im a Gal that is Thankful for many of your Videos on vehicles I've owned👍. Saved me $ on things,I can do Myself.
The next time my thermostat goes bad in my Envoy, I'm gonna take the guts out of it, reinstall the housing, bypassing it, then I'll install an inline thermostat down where the lower hose goes into the radiator. They unscrews easy and use standard thermostats , so you can pop out the thermostat when you flush your coolant without impediment to the water flow.

I've noticed that the better the quality control in the build of a vehicle, then they all have the same issues when something breaks.
Man some of the problems you guys are naming I've never ever dreamt of in my Envoy! Heating door issue what the heck is that??Over 276,000 miles & still running strong, except a cam position sensor code and upper intake gasket leak other than that she's great! I have a 2003 Envoy XLT with the 4.2ltr inline 6 with all the bells & whistles except sunroof! I love this thing and wish GM would bring it back with modern styling better interior materials and better gas mileage! I'm about to purchase a 2005 Denali XLT AWD for $300 needs engine and transmission but the body and interior are in great great condition compared to mine! I have a personal mechanic that can do the work very reasonable for me but I'm wondering about the reliability of the 5.3v8 heard they have lifter issues due to the cylinder deactivation process GM used. Is this a good buy for $300 also I can get the motor & trans for a discount because of my mechanic!!
I have the heat door issue one of the actuators not working have no feet heat and always defrost is on its a pain in the ass in the winter here in NH
You forgot the cracked exhaust manifold issue the ac condenser drips right on it if the tube isnt on or the shield isn't on the manifold allowing water to splash up at it and the insterment clusters go funky 4x4 actuator like to bust apart without warning and the fuel filter being in the tank! Big issue i own a 05 and the sending unit was from the xl
On my second manifold and need a 3rd.
I got a 2004 xuv 6 banger and my fuel filter is right on the side of the tank easy breezy. But the fuel filler neck attachment on the tank tends to crack
Great vid on a pretty great (but not perfect) vehicle. I have an 03 Envoy XL SLT with the excellent 5.3 V8. 245k miles, gobs of power with my 4.10 axle option, and relatively good mileage for a heavy V8 beast. Have had ignition key issues (wouldn't shut ignition off and release the key), Front wheelhub bearings, and replaced most of the worn out steering/suspension. There's also a battery draw, could possibly be stereo/alarm system (I just pulled fuse), OnStar system (pulled fuse), short in driver side door (nothing electrical in door works except power locks, sometimes seat heaters come on randomly), and likely frayed/grounded wires in the troublesome XL hatchback. 4X4 isn't working, and there's a loud knocking under dash related to Automatic Climate control upon starting vehic. Other than buying someone else's electrical gremlins and uninspiring soccermom-mobile handling, I love it, particularly the modified LS engine.

the headlights in mine won’t turn on all the time so i’m not able to drive it at night but the highbeams will work
Same here
It’s just the headlight relay. Just replace it, part number is 15016745. Happened to my moms envoy too
U people are just the best.
Thanks for continously informing us
+Lekona Rodrick Thanks for checking us out! 1AAuto.com
What about abs light and traction control light on?
Yep. That stabilitrack system lights.
I get 2, they go on and off randomly.
Ive never had that issue with mine its located on the shifter so u might be pushing the button
Idk why ppl talk bout the 4L60 mines has 205,000 Miles and had no issues at all
+kamaster1011 Thanks for the feedback!
Because we’ve all had them eat the 3-4 clutch pack with no warning.
Mine has over 250,000 miles on it and no problems.
Your supposed to drive all GM 4 speed transmissions in 3rd gear until above 80km/hr then put into overdrive(obviously a lower RPM gear) have driven GM's for many years and haven't had to rebuild a trans yet *touch wood*
I hear they last longer if you add an extra trans cooler. My 4L60 makes some odd noises but keeps on truckin'
My truck is back! Right on. Would you consider doing a video on replacing the push button for the rear glass release? Hoping you also sell that part. Thank you! Love your videos.
+Lindsay B We're always cycling through common cars. We'll add this repair to our list! 1AAuto.com
My GMC Envoy starts up in the morning and turns off within seconds many times. only when it's cold. almost an hour to turn on properly. After it turns on everything works perfectly the rest of the day.
Sway bar end links constantly replacing them.
Lousy design
Define constantly please. Just want to be prepared..Thank u
Thank-you from Yukon, Canada, love your site... , and will order my parts from you guys, cause you took the time too do such video's :)
Hi, I have a 2002 GMC Envoy. Today I just left work and it's accelerating all by itself to almost 2000 rpm. What do you think is wrong with it? It has almost 250,000 in it. Thank's in advance! Great videos!
+JR0CK Chillin We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
Mines just starting to do that, what did you find out?
I have asked so many on these videos about a problem I'm having with my 2002 envoy and can't get a direct answer to my question maybe it's because no one has had the same exact problem. But I'm trying one more time.
My 2002 Envoy has a little over 200,000 on it and until February of this year it has a been a great vehicle. But one day I was driving down the road at 55 mph and all of a sudden it was like I had no gas. At first it sputtered like it was running out but the gas needle said it had 1/4 tank and I knew it was not out. But I pulled over and sat there for about 10 minutes and turned the key and it cranked up instantly. I drive it about 5 miles and it happened again and I pulled over and shut it off. It would coast idle for several miles but when I pushed the pedal it got no gas. This happened 4 times until I made it home. The check engine light never came on. The next time I drove it was after the fuel filter had been replaced. It did the same thing after I drove it for 5 to 10 miles. The last time it was test driven the check engine light did come on and it said shut engine off. This had never happened before. My mechanic friend came and picked up and had it for a few weeks. The next time we test drove it it went further before it happened. It went 25 miles and this time it coasted for a mile and when the gas pedal was pushed it picked back up and it was driven another mile to his house. It has had several diagnostic tools hooked up to it but it doesn't show any codes. I replaced the battery as well as the fuel filter. But we don't know what else to do without taking it to a shop that has access to gm diagnostic app. I've seen so many videos and stories where people were advised by mechanics to replace fuel pump and after they spent a thousand dollars doing that they found out it was not the problem and instead was a sensor or some other less expensive part. Does anyone know anything about this or what it might be?
Same chassis to the Chevrolet Trailblazer.
This car seems pretty reliable i just got an 04 v6 hope everything goes good lol
Check the frame under the drivers seat, ours was rusted o the point I could put my finger through the frame. Was and had been a great vehicle..
Don’t forget the dreaded front differential leak on the 4 wheel drive envoys and trailblazers. They leak like crazy
Ignition switch on my envoy caused "reduced engine power " and gave a code pointing to the throttle body. Wasn't the throttle body, it was the ignition switch getting or not reading the correct voltage.
I just got that "reduced engine power" light on my dash recently during a -20 cold snap. Couldn't keep the engine running and wouldn't go above 30mph. Pulled over and let vehicle sit for like 10 minutes, started, drove away like nothing had ever happened. Had no clue it was possibly ignition switch until now. TY!
Key ignition done that too put a new one in couple years ago
Bruh I have a 2003 Envoy SLE with 254k miles, the only one of these issues I've ever had was the heating one, the thermostat is alright. The groaning noise actually happened once, but if you get your tires realigned it usually goes away.
My correlation code was the cam position sensor not a leaking actuator or loose harmonic balancer
#6 power steering pump
Thx for the info! I’m thinking of getting a 2002 fully loaded forest green with brown interior to camp and hike here in WA state.
I'm getting oil in the (?) intake breather box (?) on a 2004 gmc envoy. Any suggestions? Doesn't seem to have a pcv at all.
I notice this as well lmk if u find anything out
Had 2 and both had:
•passenger side rear door had problems.
•front left hub bearing
No issues with any of those 2009 however, your 4200 exhaust manifold is a ticking time bomb if you didnt get the service bulletin.
Themostat was the first to play out when he got the truck . He gotten it fix bout a month ago and now it saying the cooling fan sensor going bad . The engine light came on after we use the air in the truck .
Your videos are very helpful! Can you please do one on how to replace a mode actuator on a 2006 Envoy Denali? I have air coming out of the floor and defrost vents, but not the front vents. I have located the non-working mode actuator, but I cannot figure out how to get it out to replace it.
How about the Fuel venting issues. Ignition Coils going bad. Fuel filler neck going bad.
Good to know 👍
Ignition coils power steering water pump and transmission
Fuel vent issue will it leak gas? Cause I get lousy milage and I swear when I turn sharp the gas gauge drops. But I don't see any leaks or wet spot on the ground or clean under body parts where gas might of touched. Thanks
The gas tanks are known to get hairline cracks on top at the vent only fix is a new tank do the pump and the canister at the same time while it's down
I found it informative.
About to get a 2004 GMC Envoy like this one with 5.3L V8...Do You carry the New starters for it? If Not, what Part # do I need? I can only find the V6 ones. Thanks !
Could you plz tell me what fuse operates the license plate lights on an 2005 GMC Envoy??? Plz, I've been looking at my book & I can't seem to find it, I need help.
Thank you for the video. I have a 2002 gmc envoy slt 4 wd
question: I have a 2006 GMC envoy SLT (3rd row seating) and the check engine light is on, I think it came on because of a damaged gas cap, is that possible?
It can happen
Yes
I think you just helped me fingers crossed I'm gonna get a buddy go over this video and my car cheers and thanks
I think my ignition switch is bad on my 03. It has 102k, on my odometer. When I put the key in it won't turn over and the driver seats starts adjusting itself instead of turning over. (I got my foot on the brake while trying to turnover) I have gotten it to turn over only a few times, it runs great other than that.
Really well explained. Thanks!
Just recently I got my oil changed now the dash is saying change engine oil....
In I got a new battery now its a clicking sound in my yruck
Thank You, Kindly. Great Video. 👍👍
I have a 07 envoy was wondering if I would be ok pulling my 20ft bass boat like pull it in and taking it out of the water???
Where do I find the EBCM on a 2007 gmc envoy.
Do u have video of changing out transmission to 05 gmc envoy
This line of trucks has it's problems, but I must say the straight six is bullet proof.
+Brian Bishop Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I've got an 05. The ignition key won't turn all the way back to come out. And the headlights on turn on on hi beam. Any thoughts on what's wrong?
Thanks for your video, blessings
5.3 with afm on envoy has lifted issues
My 2005 gmc envoy 110,000 had a missfire I bought 6new spark plugs started running a little better except the coils were bad so I went to go buy 2 coils as I was changing them with the car on the car turned off. Had to have the car towed and now it’s cranking but won’t start. Anybody have any idea?
Chevrolet Trailblazer is the Chevy twin.Nice video as always gang.
+E Meyer Thanks for checking us out! 1AAuto.com
I have my drivers side headlight high and low beam go out hit the headlight a couple times and it comes back on. Any ideas?
clean the main wires going into the fuse bank and take the fuses out and clean them. Fixed my issue. The main wires had some minor corrosion and the fuses just had a bad connection.
You forget the abs light and brake light problem when the brakes lock up on take off due to bad abs speed sensor or bad abs motor.
The speedometer won’t work when this happens.
problem I had was the low beam relay kept burning out. after 2nd time we realized we didnt need a 2nd vehicle at the time and sold it
Same issue here had to get a better relay fixed it
Great for "a foot of snow."
Thank you, good information.
I replaced my ignition switch myself after countless efforts to figure out what was wrong (replaced alternator battery etc thought it was a wiring issue) eventually got to ignition switch and when I took the old ignition switch off which was clearly the one that the manufacturer had put in the car because of the way it was zip tied into all of the other elements when I took it out I noticed that one of the metal prongs that was supposed to be inserted into the switch or whatever was completely bent down flush so it had never been completely plugged in or connected in general and it was just probably catching friction which was pretty frustrating because it was a big issue I had for a long time and I couldn't figure out what it was and to know that it was from the freaking manufacturers installing it incorrectly was pretty I can't even think of a word dumb basically lol
Just had 2 out of the 5 replaced last wk
Dear 1A Auto, I have gmc envoy 2007 when I tern steering while drive sloly I feel the car like jumping on humbs. I went under the car I fond cracks on the rubber of the both racks and there is a red oil on the gear case. Can you plz tell what the problem is and how to solve it. Thx
Just got this one and it makes a weird clicking sound that comes from the drivers side front tire while driving
I have the same issue but it sounds like it’s coming from the back of the car for me
mine does too
May be wheel hub bearing
Thank you very much.
+Cesar Antonio Canales Escoto Thanks for checking us out! 1AAuto.com
Wow. I have an 03 envoy xl for a decade and none of these issues! Drive it daily to work and back and it runs better than any car I have. Only problem I have is I left my driver side window down during a rain storm and now my entire control panel is out. Cant roll up windows or lock doors from the control panel. Obv I rolled up the back windows using those switches but now my drivers side window wont roll up and its 20 degrees! Uhh
Thank you
Anytime Glen! Thank you for tuning in.
@@1AAuto Great video ! How can i tell what wheel bearing is bad ? It goes away when i make a right turn coming off interstate .Oh wait just saw the part about wiggling wheel 👍
I have an 06 GMC Envoy XL 4.2L and when it is cold out it dies meaning when I turn it over it starts but then dies if you leave it for a couple minutes and try again it is fine but it only does it when it's cold. Any ideas?
Might be a worn battery
