  • I am having issues with the security system on my 2003 Tahoe. It has the 5.3l Vortec engine. It has cut off the fuel to the vehicle. I have spoken with a mechanic and he seems to think thta I have thrown the system of synch with itself. Now the stupid thing won't start. I have tried all of the things that he told me to try and it still won't start.

    Any ideas?

    Everything about the truck still works. Electrically it seems ok. Just won't start.

    Thanks for anything in advance.

    I do have the climate control... and do not have Onstar... Mine sounds exactly like a fan with a bad bearing. And mine seems to quiet down after the vehicle warms up... at least in the beginning... Now it seems to be loud all the time. Mine is not under warranty... I wonder what they will hit me for to replace it.

    thanks to all.

  • Rob,
    My headliner fan was replaced on 3/18/03 at 15,666 miles. The total warranty charge to GM from the dealer was $79.39. My 01 YXL has the light gray headliner color. The part is called an "Aspirator" p/n 15029252, & is describled as "inside air temperature sensor".

    If you're handy, I think it comes out quite easily. I checked GM Parts Direct.com for you. That p/n currently is $39.23 list, $22.36 GM Parts Direct price plus shipping. I can check my shop manual for you, for the removal & install procedure, if you're likely to change it yourself. I don't know if the small painted grill that you see is part of the Aspirator, or separate, in case your headliner is a different color.

    Hope this helps,
    Dave

    Dave,

    I will be able to change it myself. I was looking at the headliner.. have not taken one out of Yukon before... but I am willing to give it a shot. My headliner is a tan color and so is the grill. I was going to try to pop it out... but perhaps I need to take the headliner out first? I sure appreciate you looking up the part number for me. That saved a ton of time at the dealership and $ and for that... I thank you! If you have time to look in your shop manual I would appreciate it.

    Thanks,

    Rob
  • My new 2005 Tahoe LS came with Firestone Wilderness A/Ts, P265/70R16. The dealer has them inflated at 30psi. Is this the recommended pressure? I can't seem to find an answer on Google. Any comments will be appreciated. Thanks.
  • jonnyb1jonnyb1 Posts: 32
    the pressure should be on the side of the door sill and the max should be on the tire. If I remember correctly around 35-38 should be acceptable.

    However, it is worth $400 to upgrade those {NOT VERY GOOD} Firestone Wilderness LE's to something better as they slide all over the place in the rain. Many people here get the Michelin's but I have put almost 50k miles on a set of Yokohama Geolandar's that have been great and fantastic in the rain and still will probably last another 15k miles.
  • Sorry this is a year late, but that was the same noise my 2004 Tahoe had. At highway speeds it sunded like sand/gravel/rain was hitting the windshield. Noise would go away when widshield was wet (rain, car wash, or windshield wiper fluid). My dealer put some kind of black colored adhesive (kinda like bathtub sealant) between the windshield and the black molding. That molding vibrates against the glass. Thats why when wet it was silent...water acted as a spacer. All noise gone since they did that.
  • Hello:
    Recently bought a 2000 Chevy Tahoe and not sure how many miles has exactly. The title says 90K, but there are no records in CAR FAX. It feels sm ooth and quiet and hope can drive it for long time.

    Regards
  • When my tahoe is warm, can hear a light noise.

    Could be the fuel pump and it is normally?

    My 02 LT has 74,000 miles and i just had the fuel sensor replaced last week after it wouldn't start at a 1/4 tank also. So i've been driving it around to see if the low fuel light is still working. After leaving it parked in my garage overnight and at 1/8 of a tank of gas it wouldn't start again. Now what?
  • I am new to this board so please forgive me my question has been asked before. I have a 2004 Tahoe LT, with 29,000 miles. I love love love it!!!! But I have a nagging rattle under my hood, it seems to be coming from the driver's side. On a smooth road there is no noise at all, but on a bumpy surface there is a constant rattle. I have looked under the hood (not that I know what I am looking at) I tried to shake things under there, hoping to find the reason for the rattle, and can not figure out what is causing this annoying noise. Does anyone have any suggestions as to what it may be?? Thank you

    Does it feel like it could be coming from the steering column area? There are a lot of problems with the intermediate steering shafts on these vehicles. Both my '02 Tahoe and '03 Silverado had the same problem. Both became annoying between 20k-30k miles. It's most noticable at low speeds on bumper surfaces, although when it gets worse you'll hear it/feel it in the column on smooth surfaces when turning.

    The dealer lubed the steering on my '02 and it went away for as long as I owned it (40k miles). Just last week I took my '03 Silverado in for the same problem and this time they replaced the upper intermediate steering shaft. So far so good. Just tell the dealer your steering is clunking and they should know exactly what to do.

    I have a 2003 Tahoe with interm wipers. The other day when it began raining for the first time in weeks, I used my wipers. Now they appear to be stuck in the on position (working continuously), even when the switch is turned to the off position. I pulled the fuse to stop them, but could this be a relay problem? Any help would be appreciated.
  • Does anyone know exactly what is needed when the dashboard warning light flashes "Service 4 Wheel Drive" (I mean besides the obvious) Do I need to change the transaxle fluid? anything else? Thanks
  • dardson1dardson1 Posts: 696
    I'd bet the previous poster is correct. The rattle (you can feel in the steering wheel in the early stages and audible as time goes by) is especially apparent in a slow turn at a rough intersection. For a few years they just lubed the steering column for a 5k mile band-aid, but they now have a replacement part that is a fix. It's working (so far) on mine. If all this rings true, just tell the service guy you've got a rattle you feel through the steering column. They will know exactly what to do. It's free under warranty and not very expensive if not. Good luck.

    If the SERVICE 4WD message comes on, there may be a problem with the
    automatic transfer case and service is required.

    If the message was only displayed briefly you can probably ignore the message.

    The message on my 2002 Tahoe displayed briefly, once. It has never displayed again and I have not had any problems with the 4Wheel Drive system.

    If the message continues to be displayed the vehicle will have to be serviced to determine what is wrong with the 4Wheel Drive system.

    The message has nothing to do with changing the transfer case or axle fluids.

    My 2000 Tahoe flashed "Service 4 Wheel Drive" occasionally and then, as time went on, more frequently. I noticed the light would come on after hitting a bump or jamming on the brakes -- conditions causing body flex.

    Eventually I had problems going into and out of 4WD -- seemed I had to jiggle the buttons repeatedly to make the change. But, since I rarely use 4WD, and 2WD seemed to function properly I continued to ignore the warnings.

    As the message became more frequent, I did a little Internet research and found this to be a common problem, often caused by a defective push-button switch. I bought a new switch from GMPartsDirect.com (P/N 15709327, $33.94 + shipping).

    After installing the switch I am able to go in and out of 4WD without problems and the warning light has NEVER come on

    "GM Insists Neither Stiff Competition nor Rising Fuel Prices Will Keep It From Earning Big Profits With Full-Size SUVs"

    GM's new Full Size SUVs (Inside Line)

    It's being discussed in the 2007 Chevrolet Tahoe/GMC Yukon discussion.

  • Dave,

    Did you ever ascertain if this fix can be done by a skilled do it yourselfer, I have the same problem on my 03 Tahoe and not sure if warranty will cover it

    Thanks,
    Jay
  • Jay & Rob,

    I am sorry that I have not gotten back to you on the removal & reinstallation of the aspirator in the headliner based on the GMC shop manual. I was out of town for a few days, & then got tied up in so many things including getting my 01 YXL into the dealer & fixed for the antilock brake recall. Mine was actuating 3 out of 4 times on normal braking.

    I promise to check the shop manual tonight when at home, & let you know what it says. Jay, if your truck is still within the 3 years/36K miles, the temperature sensor fan (aspirator) should be covered by warranty. I think it must be fairly easy to replace, as the total warranty charge to GM was $79.39 for parts & labor.

    Dave
