  • same problem here with my 2004 tahoe z71 - chevy sucks!!! they do not stand by their products!!! :mad:
  • i have a 2004 tahoe z71 and the speedometer and another gauge both broke 2 years ago and I took it to dealer to have it checked out they said pay $900 and we can fix it. I didn't have that much to drop on a simple problem. Now they tell me it was a defective part! but they won't fix it now! chevy sucks!!!

    I have a 2005 tahoe w/ the digital climate control system. It seems to only have 2 settings either 60 or 90. the heat only works with the control set to 90. if i put it at 89 it goes to the coldest setting.

    does anyone have any ideas on how to fix?
  • I have the exact problem with a 2003 Tahoe. Tried replacing the entire heating unit into the dash. No help. Looking for answer.
  • Found the answer to 2003 Tahoe climate controll problem. Set on 90 heats and 89 and less goes to cold air. No inbetween. Look up from drivers seat to see small plastic in headliner. Looks like small speaker, but is not. Under the headliner is a small sensor type gizmo. Has fan and very small wire with black ball on end. Reminds me of a very small antena. This works with the climate controll system. New part was less then $30.00 new. Plugged it in which resulted in happy ending.
  • Can any mechanic put in transfer case fluid or does it have to be a chevy dealer???

  • chosschoss Posts: 2
    Thank you. That works and saved me a lot of money. I went to a dealer and they said it would be a few hundred $$$ just to find the root of the problem. I got the part from NAPA for just over $30.

    Thanks again.
  • My 2004 Tahoe just started doing the same thing, did you ever get a response/repair?

    I have a problem with my right rear turn signal. When I have my lights on the right light shows but when applying the brake and turning on the signal light there is nothing. I changed the module 3 times and still nothing. My front right signal light flashes very fast. Its just weird how the front signal works but the back doesn't. I rigged it up by placing a wire from the front signal light to the rear and it worked. Has anyone had this problem and found a solution. :mad:
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,570
    I'd say you have a bad ground in the rear light. By "module" do you mean the entire rear light assembly or just the "flasher" relay? You might try cleaning up the bulb socket and also running a ground wire from one of the bolts that holds the rear tailight assembly to some bare metal on the body.

    I don't know if it is only the "flasher" relay because when I turn on the lights either it be the parks or headlights the right rear light does come on. Its when I press my brake it will not show the brake light but its still red and when I turn my right flasher on it will only flash in the front and not the back. And it flashes very fast in the front. I changed those modules a few times, one time it worked for a month and burned out then when I changed them again there was nothing. I cleaned the bulb socket so I was starting to think that it was something electrical.
    So if I run a ground wire to some bare metal on the body and it starts working do u suggest that it might be an electrical shortage or something. I appreciate the feedback. Thanks
  • Assuming the bulb is dual filament, what you have described tells me the brake/turn filament has blown. try fitting a new bulb.
  • simmysimmy Posts: 5
    I'm sorry but what is a dual As for the bulbs I've changed those when I bought the 3 modules. I was just going to take it to the electric shop and let them figure it out. I appreciate all the help, everyone has been very helpful. But if you think I don't need to take it to the shop please let me know I might save a few hundred dollars. :)
  • I had a similar problem, and I found on the internet where to buy the board that is INSIDE the thing, where you plug the bulbs? ....ok...that one....I paid like 20 bucks to replace that, I changed it myself cause it REALLY EASY, and problem solved. Hope helps you too.....they get old you know.....if you change that board AND the bulbs, you should be ok.....
  • simmysimmy Posts: 5
    Yeah I changed it 3 times, the first time it worked then the others didn't. I'm starting to think its something electrical... Thanks for your feedback :)
  • had to replace rear engine cover gasket.were rear main seal goes. i got the gasket at dealer part # gm#1254293 is about 30 dollar.had to remove transmisson.
  • When your engine has 150K miles & more, & your leaking at the rear of the block, quite often the rear main seal is the culprit. However, if you replace the rear seal without installing a sleeve on the rear of the crankshaft, the new seal will most likely start leaking in a very short time. The rear journal on the crankshaft will have developed a wear groove where the seal seals against it. This sleeve will slide right over the crankshaft covering the grove worn into the crank, thus giving the new seal a smooth, virgin surface to seal against. In the post of fmarin he didn't mention installing this sleeve, & perhaps that is the reason his engine still has a leak. I hope this may be helpfull, & good luck to both of you.

    I just recently took my Tahoe in for an oil change and the maintenance department at the Chevy Dealership suggested I had an oil leak. I hadn't noticed anything previously.
    The comment on the report reads as follows;


    This rig only has 5443 miles on it. yes it is under warranty but once these people start messing with stuff....
    The mechanic said they had done one of these jobs before.
    Has anyone else seen this issue before?
    Since the car is so new should I be contacting Chevy?
    Any suggestions/information?
  • rockman59rockman59 Posts: 250
    Since the vehicle is under warranty your dealer is the place to get it fixed. Unusual for a rear main seal to be leaking at this low mileage. Make sure they check to see that the oil is not coming from some other part of the engine and dripping down to the transmission area.

    Our 2004 Tahoe has always had some knocking noise in the dash, of course it wouldn't perform on demand while it was under warranty. Now it is more persistent. It sounds like knocking, it happens mainly when the heat is on and the controls are set all the way to the top of the red. When we back it down 2-3 notches the noise usually stops. I do think it does it with the a/c too, though haven't tried to isolate at what temp control it does it. I think maybe it has to do with the blower motor. In my Taurus that was an easy do-it-yourself. Any thoughts on what it is? ( I think I hear it best when my ear is to a vent--but noises are so hard to tell where they are coming from...)
  • 73shark73shark Posts: 325
    If you complained about this during warranty then take it back and show them that it's still doing it. They should do something about it.

    It could be that something got sucked into the fan.
  • We have a 2005 Chevy Tahoe. We just started getting a message on the dash saying to "Service 4WD". This message seems to go away after shutting off the motor and sometimes doesn't show up for a couple of days. Is this a bad switch or does it mean we need to check the lube level in the transfer case or some other issue? The Tahoe just turned over 36,000 miles. I have looked for service bulletins for this but have found nothing so far.
    Look forward to your response.

    You might read back a few posts. This seems to have come up before:
