Chevy Tahoe Maintenance and Repair

    These lights come on together and stay on at various times. Can anyone provide a diagnosis?

    Thank You

    Can you buy the little silver strips that go inside the black door strips on all 4 door?

    Take it and have any error codes read out of the computer, many auto parts chains will do it for free.

    Brake Warning indicator is set by:
    - BCM body control module detects park brake is engaged
    - BCM detects low brake fluid condition
    - IPC performs bulb check
    - EBCM detects ABS disablilng malfunction

    ABS indicator is set by:
    - EBCM detects an ABS disabling malfunction
    - IPC performs bulb check
    - IPC detects a loss of serial data communication w/EBCM
    - a DTC is set during previous ignition cycle

    Thank You,

    When they come on, they come on together.
  • Hi everyone and thanks in advance for your input. I have a 95 tahoe. The 4 wheel drive has worked without fail for as long as i have had it (6 years). Just recently the 4 wheel drive would not engage althought the lights indicate that it had engaged. After about 3 days of this the indicator light stopped coming on and now i am without 4 wheel drive. Its not too big of an issue right now as the snow has melted but i would like to trouble shoot this in the cheapest way possible. ie forum advice. Thanks again.
  • I have the same problem with an 04 Suburban. I put in some "liquid glass" and drove it for about an hour. It seems to have slowed the leak, but I am still using too much coolant. What radiator sealer did you use and is it still holding? As you know, GM is not going to help.

    Bars Leak is the best I've ever found over the years.

    Jar of black juice w/what looks like little black turds in it.
  • Had the same clunking noise in the steering in my 2001 Tahoe. I took it in in 2004 to be looked at by the dealership, only to be told they could not duplicate the problem. My husband, at the time, was far too timid to speak up to them. They kept making me feel like I was just another stupid woman who doesn't know anything. I finally stormed down there and spoke to the Service Manager (who had recently taken over for the last moron). He said he WAS familiar with the noise issues that the Tahoe was having, and all they did was tighten the lower crossmember to the lower control arms and did a front suspension replace. Has been just fine up until recently. Since Chevy keeps stating that they are aware of this issue, but that it poses no safety threat. I have to take it in for a tune-up anyway, so I plan to have them take another look at the crossmember to make sure that it doesn't need tightening again. We shall see.
  • I have an '01 Tahoe. It is governed at approx. 98 - 100 mph. I learned this the hard way, and lost that race. Not sure about the '02 limit, but I would imagine it would not be much different.

    Hope this helps. You should be able to find something in writing, somewhere
    on-line, that backs this up.

    You may have lost the race but not your life. There's a reason it's limited to ~100 mph.

    Could someone tell me what would cause the Service Engine Soon light to come on, my truck runs fine. What do I need to check to repair this issue Any Ideas. I don't know where to start looking for a problem and don't have the $$ to take it to shop.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    That's what engine lights are for, so that you will plug in a scanning tool and find out the trouble code. This is your cue to do that.

    Long shots might be a) a loose gas cap or b) some kind of vacuum leak, loose hose, etc.
  • dustie1dustie1 Posts: 17
    We tried the loose gas cap thing and the light went out but Sunday evening it came back on. I don't have the money to take it to a shop though. But thanks for the information.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    Well you'll spend more money guessing blindly in the dark than you will paying someone to read the codes. I'm not sure I understand your resistance to this. Possibly you can get someplace like Autozone read the code for free for you.

    If the light went out briefly when you fiddled with the cap, you might have a vacuum leak or other problem with the evaporative emissions system. The code would tell you this.
  • dustie1dustie1 Posts: 17
    I forgot about AutoZone thank you for reminding me I will do that, husband thinks I need a new gas cap so if the codes say there is a emission vacuum leak then we don't have to replace the cap. Thank you kindly. :)

    well iv had that problem with mine before and it was the the number 1 plug wire but it could be anything. like an O2 sensor. what i did was when i came on took it to autozone or any parts store like that and had them hook up the code reader to it and that would give you a pretty good area to look at and best of all its free. you just have to make sure the light is on when you take it.
  • dustie1dustie1 Posts: 17
    Yeah, I plan on doing the AutoZone thing as soon as the light comes back on again. Thank you for the input. :)
  • dustie1dustie1 Posts: 17
    How much would an air cond condensor cost? I hit a deer in Nov and the antler went through the air condensor and I have no air. Any answers will be helpful.
  • kiawahkiawah Posts: 3,666
    call pepboys or autozone
  • rockman59rockman59 Posts: 250
    Online parts suppliers are selling the Tahoe condensers for around $225.00.
  • arriearrie Posts: 312
    Take it to AutoZone or other parts store where they will read the codes for you to find out why the SES light is on.

  • 73shark73shark Posts: 325
    I hope you had the condensor lines capped off to prevent the rest of the system from becoming contaminated. :cry: Otherwise other components may be damaged. :sick:
  • dustie1dustie1 Posts: 17
    Nope didn't know that. Maybe that's why the service engine light comes on. Wow thank you.

    i have a 1998 tahoe w/20" wheels. I have too much play in steering wheel & the vehicle is always pulling left or right. I have went to several repair shops in the last few years w/no success. I was also told to seek out a front end specialist. Can someone tell me how to fix this problem? I live in the New York area. If I should go to a front end specialist, does anyone know one? Help!!!
  • 06/15/2009

    Did you ever find out what the knocking noise was. I have an '04 Tahoe and I'm experiencing the same situation. Your post was 03/05/2008, so you probably don't have the same Tahoe. If you were able to get it diagnosed, I would be very interested to know what you found out.

    Hi there, my name is Tina, I am in Wyoming. I have a 2002 Tahoe, and it feels like my tranny is slipping. It revs up but does not really catch right away. It almost feels like a fuel injection problem and by the way we just put in a fuel pump last month and did it ourself. Could you give me an opinion please I was stranded in Ft. Collins, CO. and decided to turn back home to Wyoming just in case something was very wrong. I am pregnant and have 3 kids with me and I am in a panic. I have done the obvious like check the fluid and added some. It marked full. I checked the fluid in neutral, I think that is the right way. ???? Could it just be the Torque converter?
  • My 1996 Tahoe was having terrible problems starting and running correctly. The initial diagnosis was the crankshaft position switch was malfunctioning. After almost $2000 dollars of replacing the sensor, engine tune-up, fuel filter and fuel pump I was still having the same problems, but not all the time. I had a local mechanic due the work and he said take it to Chevy and have them diagnose the problem, which they determined was still the crankshaft position switch was malfunctioning. Since my mechanic had done the original work I took the Tahoe back to him with the Chevy diagnosis problem. He crawled under the truck with it running and saw the sensor moving around while it was running. He took the sensor out and discovered that one of the mounting bolts screws into a brass fitting inside the plastic timing chain cover. The brass fitting was loose and just needed a screw driver inserted into it to spread it to increase the tension on the plastic cover. My mechanic put it back together and it resolved all my problems, meaning most of the $2000 dollars I had spent trying to fix a problem that ended up being caused by maybe a 25 cent brass fitting in a plastic cover. Live and Learn. By the way my 1996 Tahoe has almost 154000 miles on it with the original engine and transmission.

    How much trouble is it to change out the AC fan blower switch on the dash panel on the Tahoe. Mine just lost the three lower fan speeds. Can it be done without taking the dash apart? Thanks Doc.
  • kiawahkiawah Posts: 3,666
    check the blower resistor bank, in the air plenum, by the squirrel cage.

    Still have the truck, and the noise. My husband said something about some door or flap or something. I don't know if he knows for sure. It sure seems related to the a/c system. If he moves the temperature lever a little off cold or hot it seems to not do it as much. It does it with heat or a/c I think. I'm not sure exactly what he was told, and I don't think it was ever officially checked out, but no real prblems with anything at this point. Did you get yours diagnosed?
