Chevy Tahoe Maintenance and Repair



  • dblhelixdblhelix Posts: 1
    Recently noted a gurgling sound in the dash of my '04 tahoe w/45K miles. Best description is it sounds like water sloshing around inside the dash, both behind the instrument panel and the glove box. The noise seems affected by engine RPM, but the engine itself sounds fine. Maybe related to the cooling system? Any ideas on what could be causing this? Thanks!

    I am considering the purchase of a '05 Z71 with 25,000 miles. It is in very good condition and this is my second tahoe purchase (first Z71). Any thoughts from other Z71 owners about any problems you have had in the past or currently having with the '05 model.

    I have an 01 Z71, last night I ended up in a clay ditch on the side of the road in GA.... Anyways I ended up getting out by aggressively rocking back and forth. After I got it out I noticed the power steering not working 100%, today the pump is making noise. Planning on replacing the pump, any suggestions, any other similar problems???

    Have '05 LS with auto suspension with 5.3L Flex Fuel. Get Avg. Econ of 17.4. Have since the beginning. Currently has 23K miles as of this writing.

    Have a strange problem that dealers, as well as myself have yet to figure out. It only happens when in the Auto 4WD mode. When accelerating b/w 25-40 miles hour, I can really feel a noticeable skipping, hesitation, or an emulated feeling of misfiring.

    First of all, it’s very difficult to articulate. However, very rough feeling needless to say. Doesn't happen in 2WD mode at all. Smooth as a baby's bottom. All this on smooth highway. Ran all scanners to no avail. Last dealer reset tranny memory, and obviously didn't work.

    My first inclination was it has to be the tires or the wheels are unbalanced, because the AUTO 4WD mechanism is looking a situation in which the vehicle needs 4 wheel drive or else it drives no different than 2WD and that skipping is in search of something, like the tires are trying to grab or dig in the road surface. .

    If anybody has had this problem or similar problem and/or can help, please reply.

    Thanks in advance.

    I hear a similar sound in my 2002 Tahoe Z71. I think it comes from the air ducts. Seems to only happen when it rains, like some water may be getting down into the ducts and sloching around. If anyone know of a fix, please let me know!

    Did you ever get the weird feel in the gas pedal resolved? I have the same thing in my '06.

    I just bought a 2002 Z71 Tahoe in February 2006 with 68,000 miles.

    Every cold start, there was the engine knock for about 1 minute and then it went away.

    At my next oil change, rather than stick to the owner's manual oil recommendation, I used Castrol 20W50 with one quart of the Lucas oil additive in March 2006.

    It took a bit of driving I believe to distribute the oil additive, but the knocking has been gone for over a month already. With the thick oil my gas mileage is 13-16 mpg. I’m not sure this solution will work in the great white north, but I am very encouraged with the results here in Florida.
  • I have a 99 tahoe and need to reconnect the automatic transmission. I had it towed and the tow truck driver had to disconnect it to get up on the flatbed. I think I know where it is if the cable that runs the length of the car on the drivers side is it. Also when turned on, the gear shifter is in 1st gear position. Any help would be greatly appreciated.

    Beware that you are in for serious tranny trouble! If you don't replace it now, you will in the future. My 03 Tahoe just blew it's 4th (yes, 4th) tranny yesterday and it hasn't even hit 54000 miles yet. The first tranny started to go out by slipping just a little like you're describing. A couple of weeks later it was gone. The replacement slipped from day one (both were under warranty) and the dealer said it "just needed to settle" being new and all. Second dealer disagreed and replaced that one. Nine thousand miles later and "boom" drive and 3rd are gone again!

    There's been a chevy in my driveway my whole life but this on'e getting a for sale sign as soon as I get it back!

    So far, my 2002 Z71 Tahoe tranny works fine. It was replaced about 20,000 miles ago with a brand new one by a dealership in Duluth GA under extended warrantee. What problems do these trannys have and is there a particular series to avoid?

    The previous owner also had a brand new a/c compressor installed which so far works fine.

    I've got a 99 Tahoe that I've had to replace the altenator on. Problem is that it still won't charge the battery. In the altenator installation instructions it states that the system may have to be reset by a code reader. Anyone have any other methods of reseting the system other than with a code reader? Only thing I didn't do per the instructions was that I pulled the positve off the battery first, not the negative as they instructed. Other than that I followed the instructions. How do I correct the reverse bias condition they mention?

    My 2002 Tahoe blew it's trans at 28,000 (under warranty)and 54,000(out of warranty). Front differential replaced at 51,000($1800) and again at 52,000(n/c). I have no faith in this vehicle. It was between the Tahoe and the Sequoia and now I know which one I should have bought.

    I have owned my 2006 Tahoe for about three months now. No problems until this week. Noticed that my cigarette lighter (which I use for cell phone charger) not working. Neither is the other "accessory" outlet. So, I check fuse and its blown. Replaced fuse with cell phone charger plugged in and fuse blows instantly. Unplug cell phone, replace fuse and it works. It will even heat up the cig lighter with no problems. But, it blew again once I plugged cell phone up. This has occurred out of the blue. Any suggestions? I'm not too worried about not being able to use outlet to charge cell phone, but am worried that there might be a bigger problem somewhere. Help.

    Maybe its the cellphone charger?

    Hi, I'm new here, and my first topic of course is going to be something about my new truck. I JUST bought this Tahoe home friday night. We haven't signed the paperwork till tonight (Monday).
    First thing, the truck runs good. Bad thing, the Tranny is making a hard "clank" noise everytime it shifts to 2rd or to 3rd gear at 1500 RPM. And when it slows down, it does the same thing...

    Is it something that could be easily fixed? What could it be? Does it need a new Transmission already?
  • shinesleeshineslee Posts: 2
    Could be the cellphone charger, but I have used that same charger ever since I bought the vehicle three months ago. There haven't been any problems with the lighter outlet or the cellphone charger until now. I'll test out another charger today to see if that might be the problem.

    have owned my '04 Z71 for about 2 and 1/2 years. When originally purchased took in several times for engine "ticking" noise after start ups. Sounds just like a lifter ticking. Was advised it was normal engine noise. Now, since I have rolled past the 36,000 warranty period (39K), engine ticks upon starting in the mornings, ticks when started after sitting for 30 mins or more. ticking noise goes away if I rev the accelerator. Ticking is very noticable but not sure how to proceed. Anyone else out there have a ticking engine? I have the 5.3L V8. We have added a synthetic oil treatment but has not quieted the tick. Gas Mileage hasn't changed, not burning oil. Anyone else out there experiencing this kind of engine tick? :confuse:

    See #133

    20W50 and 20% Lucus oil additive will quite it.

    Had 2002 2500 HD with 6.0 ltr engine with lifter problems from the start. Loudest when started in the am and then when warmed up would dissapear. Chevy refused to fix but gave me a 100,000 mile power train warranty as compensation. You should press them as this was a known problem.
  • The autoride in my 2001 tahoe just stopped working. I checked the fuses inside and all is well. I then ran a hot wire to the pump and it seemed to work. Does anyone know if there is a inline fuse or relay anywhere. I searched under the truck with out any luck.
  • Dealer can never duplicate and therefore can never attempt repairs. I am confident this defect will leave me stranded one day. Just not sure where or when.

    Someone told me it was because of armor all. I know a few other people with this problem too. Haven't taken it to the dealer. Anyone know for sure what causes that, if it's under warranty, and if not is there anyway to fix it. It looks really bad. Thanks!

    I have a 99 tahoe that has no right rear turn signal or brake light, tail light works. One of the bulbs had a broken element, but I replaced all 3 . still the same . Right front signal works but flashes about twice as quickly as it should. I did unhook the left taillight and plug it into the right side . still the same thing . There is a black plastic "combination" under the dash . My thinking is that since the brake light also is not working, the flasher would not be the problem . Any one have any ideas or experience with this ? Thank you
  • sasz71sasz71 Posts: 14
    If you see black, it's probably the dash under the paint. The dash board and leather seats are painted and that paint or dye comes off real easy. Only use a mild cleaner if necessary and do not put silicones, armor alls, etc on the dash which likely already voided your warrantee.

    To fix, your best option is to have a trim specialist, usually a contractor that visits dealerhsips to do the touchup work. He or she will spray paint it for you. The matching of the colors is worth their cost, likely under $100.

    I have had the same problem with my Tahoe which is also a 99. Luckly for me when we replaced the fuel pump we cut a trap door from the back seat under the carpet. Well anyway mine was doing the same thing so i would knock on the fuel pump twice and it would start. I got sick of doing that and figured out that the plug for the fuel pump had a short in it and since replaced no problems. May work for you but u might have to drop the tank to do so.

    Re: 1997 Chevy Tahoe 350 Engine
    I decided to replace leaking oil lines from front radiator to oil filter housing. When lines are hooked up, they leak. Cannot determine why they leak.

    Anyone have any ideas????

    Thank You,

    50% of the time my brakes pulsate, really annoying. Road conditions do nor warrent this. Feels like you really can not come to a hard stop, also pedal is not real hard. I have replaced rotors, pads, master cylinder. Although master cylinder was a rebuilt. I have read where your rear brakes could be the problem but shoes have been replaced and they are in great condition. Any ideas would be appreciated. :confuse:

    When reconnecting the cable, be sure the shift indicator sensor is in the correct position, otherwise you will
    get a false gear indication.
