    i'm having a problem with the electronic portion of the gauge cluster,,where the gear shift indicator showing the gear and milage of the car seems to flicker on and off and the computer service center seems to do the same,,,what could it be :confuse:

    Smart move having the extended warranty. My 04 Denali is in the shop right now having the front and rear "actuators" replaced along with the intermediate shaft and steering gear. My wallet says "ouch". Does this sound right to anyone out there. I don't mind having the vehicle serviced because it has been great the last 5 years and 115,000 miles just don't want to get screwed.

    Did you ever straighten out the aout leveling issue. If so ours contin ues to kick on and off for no apparent reason. We would appreciate your learning curve help
  • tsuttertsutter Member Posts: 4
    we had the same problem with our 2007 yukon and i put a scanner on it and it said something was wrong with the accelerator sensor. I unplugged the wiring harness that is hooked to the accelerator pedal and blew some air in it an plugged it back in and never had a problem with it AGAIN..... Shop was going to charge me no less 200.00 and i did it for nothing..... GOOD LUCK and let me know if this pans out....

    If your Auto-leveling system (compressor) continues to turn ON and OFF without any change to the carrying load in the vehicle, then its likely that your system is experiencing a small leak (one of the shocks or line/hose); one of the places I would first check is the hose connection at each shock (perhaps use some soapy water... ??), then move each hose (for any crease) back track to the compressor... Its a long shot, but there is a potential for a bad level sensor switch... but not very likely in my opinion. Good Luck !

    Thanks I will try it

    :mad: Hello out there. I recently had the steering gear replaced on my 04 Denali by the dealership service dept. Vehicle rides great except when on rough or uneven pavement there is a loud vibration/rattling sound coming from the front left side. Took it back to them 4 times already and get all kinds of BS like "we can't make the vehicle replicate the symptom" or "that's your anti-lock brake motor engaging". I asked, why would it engage when I'm not braking? and the vehicle didn't have this problem before you all serviced it, reply "we don't know" but they made no attempt to diagnose the problem. Does anyone have a suggestion or idea of what's wrong? I'm writing a complaint letter to the dealership owner, management and GM. Thanks.
    sorry for the long post

    I have 1999 yukon denali. There is a high pitch sqweel under the hood and it is not a belt. Could this be alternator? How do I get free online service manual or illustrated step by step how to change alternator information? Will this be a pricey fix?
  • circlewcirclew Member Posts: 8,666
    It could be the water pump...ours was squealing for over 1 year (quieted down after warm up) and then the leak started. (2003 Denali)

    If the alternator is charging the battery, it's probably good.

    usually the high pitch sound come from a belt,since you have a tensioner on the belt it is unlikely, a bad belt could do it. We are talking about a belt on its last cycle.Usually its something rotating like a pulley, water pump is one of them, check everything that is rotating.
  • rshtrsht Member Posts: 277
    Agree with both circlew and antifreeeez, also make sure the tensioner is within rang. When a belt gets too old it may stretch far more than the tensioner can apply the appropriate force... Does the squeal gets louder (changes pitch) as you accelerate? Signs of a worn belt/rubber can be a glazed surface, cracks... A couple of ways I know to see if its really the belt that's causing the squeal is to apply a thin layer of DRY soap (use a New Soap bar) on to the belt's surface (up/out, down/in and sides) or use a belt dressing spray - Never do this with the engine running and/or hot - NEVER. If its indeed a belt problem, as you applied either dry soap or dressing the squeal will disappear when the engine is running for a few minutes or until the soap/dressing wears out. Good Luck!
  • circlewcirclew Member Posts: 8,666
    My Bro is a life=long mechanic and says the belt is easy to change so if you can do it yourself, that is a cheap elimination to find the culprit.

    The belt on ours was changed at around 50K so it was an easy elimination. The alternator was working so it came down to the wp for us.

    ITS THE CLUSTER. I TOOK MINE IN BECAUSE OF SAME PROBLEM. THEY TOLD ME IT WAS ON RECALL. ALL DENALI OWNERS HAVING THIS PROBLEM SHOULD CHECK WITH DEALER BEFORE SPENDING MONEY.
  • circlewcirclew Member Posts: 8,666
    I did see the recall since I had my issue. Thanks for the tip.

    I just replaced all the stepper motors in my cluster. I bought them from a guy on e-bay for $45 including shipping. It was easy and did not take long at all and fixed my problem of the speedo sticking at dif speeds...........Scott
  • circlewcirclew Member Posts: 8,666
    Excellent. That would probably cost over $500 at the dealer I estimate.

    I have a 2000 yukon xl with 124k on it and for some reason it has been dieing on me at the worst possible moments!! I was cruising on the interstate and everything was fine but then it was acting like it was running out of gas, so I pulled over and thought it had died, but it was barely running at a super low idle, and when I pressed the gas pedal to rev it up it did die, I thought the guage was wrong and I was out of fuel, it showed over a quarter tank, and wouldnt start, I waited a while to start, and it fired up but it was still a rough idle so I gave it some gas to blow it out a little and it came back to life, another example would be when I'm running errands around town and shut it off and start back up at 5 or 6 stops it does that real low idle chugging thing again, it almost acts like the fuel pump is overheating or vapor locking?? any ideas or help would be appreciated, it is my main vehicle and need a quick fix??? it is the 5.3L 4x4.
  • jacyndaearljacyndaearl Member Posts: 7
    Sounds like a fuel pump possibly
  • showboatershowboater Member Posts: 2
    yeah I think my worst fears are realized, anyone know where the best deal on a new and reliable fuel pump would be???
  • wickn2lowickn2lo Member Posts: 3
    The seat issue is the control module for the seat i just got mine replaced and it fixed the pronlem.
  • antifreeeezantifreeeez Member Posts: 9
    Have anbody post anything about fixing the lost of air due to the connector or line. I hear alot about replacing the shock but what if the shocks are fine. what are the likelyhood of it being the sensor or how many sensor are their related to this system. I'm leaking slowly and it comes on more often when its full of gas. Just trying to find out if i can fix just the line.
  • rshtrsht Member Posts: 277
    I have seen a few people with the autoride problems in this forum. They generally went with none OEM replacements options such as aftermarket Gas charged shocks by Bilstein by disabled the OEM Autoride system (there are other forums that talks about how to disable the error message from being displayed on your dash), others are some what divided by the following:
    1. replaced with GM's Z71 equipment (I believe by Bilstein)
    2. replaced OEM shocks to Bilstein replacement at less $$ (also air shocks through Arnott Inc.)
    http://www.arnottindustries.com/
    3. replaced their OEM compressor with new
    4. stick with OEM replacement shocks; but through a 3rd party vendor like Arnott at a cheaper price than from GM or local GM dealership...
    I have not heard of anyone with air-line issues; but I would think to check that, soapy water may be the best...

    My vehicle has started to idle weird. It runs fine when driving but when I come to a stop it acts like its going to die then idles fine. If I hit the gas pedal then let off it does it again. Also when sitting at idle it does it from time to time. This just started happening and I am not sure what the cause could be. There are no check engine lights on. I had the alternator and battery checked just for s&g's. I have also replaced the spark plugs which it needed really bad. Any suggestions?
  • circlewcirclew Member Posts: 8,666
    Add some FI cleaner, replace the gas filter and see if that helps. It worked for me a few miles back....

  • rshtrsht Member Posts: 277
    Does the rough idle happen when the engine is cold (before its warmed-up)? If not, then you may have moisture in your distributor (or electronic system some where).

    2008 model, still under warranty. Any others? Thanks.

    I have a 2006 Yukon Denali and until recently with no sign of issues I woke up to start my car and it would not start. I got a boost and it started. It was fine all day until the next morning. I go to start my car again and I need a boost. I go to have the battery checked and it appeared to be defective ok so I exchanged the battery. It worked fine for 2 days and poof today it happened again. I go to start my car and it would not start. I get a boost and its totally fine. The alternator and engine check out fine. Please help me with this. Im clueless when it comes to mechanical problems and cars. Anyone else had this issue before?

    Sounds like a bad battery drain then:

  • lurker55lurker55 Member Posts: 1
    Hi

    I have a 2004 Yukon Denali that just had the steering box replaced. Now, all the controls on the steering wheel are inoperative and I am getting inoperative air bag and stabili-track disabled messages. The mechanic said he touched nothing in the passenger area. I figure that a connector is loose or a fuse may have gotten blown. I do not see a loose connector and I have no idea which fuse may be powering the steering wheel controls. If somebody can point me in the right direction to get this fixed, that would be great.

    Any help will be appreciated

    Thanks

    Twice during the last five times we stopped to refuel our 2007 Denali it would not start after refuelling. All the power was there but there was nothing when the key turned, not even a click. The service engine light remained on but there is nothing in the book to suggest a problem or reason. The first time we had it towed to a dealer in late evening but when we went back in the morning we were told it started right up. The second time we just pushed it behind the station and came back for it in the morning when it started no problem for us too. I thought it might have something to do with a worn fuel cap but took it off and put it back on numerous times to no avail. Anyone else had this problem or know of a sensor that may have to be changed?

    Hello,
    I am from General Motors Customer Service. How long has this problem been occurring? Do you currently have a case with GM? If so, what is the case number? Is the vehicle currently under warranty? Did the dealership say any codes came up when the service engine soon light was on? Thank you,

    We bought it as a second owner in November 2009. The problem started just recently in early March, 2010, maybe 5 tanks of gas. We don't have a case or number as a dealer has never seen the problem nor seen the service engine light on. We did purchase the extended warranty. We called Onstar to run a diagnostic but they couldn't find anything wrong.
    Thanks for your interest.
  • gmcustsvcgmcustsvc Member Posts: 4,252
    Hello,
    I think I would like one our agents to look at your situation for you. In order to do that I will need your contact information, dealership, VIN, and current mileage. You can direct message me all of the information. Just so you know they are going to require that you take the vehicle to a dealership to have it diagnosed. Thank you,

    We've had this vehicle since Nov of 2004 and have had NO PROBLEMS - until about a month ago. I noted an INTERMITTENT grinding/scraping noise in the rear. I took the car to our auto center (we're Navy - stationed in Naples, Italy) - the mechanic said it was our rear brake pads. I ordered the rear brake "kit" from our dealer in North Carolina. When we changed the pads the old ones still had around 50% of the pads left. The car did fine, initially. The following day we went on an extended drive, after about 20 mins we experienced the grinding/grating noise again - it seems to be coming from the rear passenger-side tire area. Has anyone heard of a GMC TSB for the parking brake? Can you tell me the TSB number? Perhaps if someone had this same problem and had it resolved you can tell me about it? Since we're in Naples we have no GMC dealership to take it to, so any help/advice you can offer will be greatly appreciated! P.S. I LOVE my Denali - it's the best handling, most comfortable car I've ever owned - sure don't want to give anyone the idea that it's a lemon! The only thing we've had to do with this vehicle was put on new tires...until now!

    I have had driver door acuator replaced before 36000 mile's now the other 3 door are acting up only working when they feel like it. I have now went over the warrenty but I'm not happy that all 3 went out at the same time. Should I complain to gmc because I have read other blogs where people have the same problem. :lemon:
