Chevy S10/GMC S15-Sonoma: Problems & Solutions



  • turtle4turtle4 Posts: 1
    I would like to know if you found out what the problem was. I am having the same problem that you described. I have a 99 S-10 ext. cab. So far I have taken my truck to a small shop and after 3 days they don't know whats causing the vibration and growling noise. I have also taken it to my local Chevy dealer and after 5 different techs and 4 hours of trouble shooting they can't tell me where the noise is coming from. Help, Help

    We have an 02 Chevy S10 ZR2. We had a hissing sound coming from the air controller at about 20000 brought it in and they said the seals were bad. Probably 15000 miles later the hissing sounds was back. Brought it in and same problem. The dealer said it was the vacuum lines sucking in antifreeze and the antifreeze was eating the seals. So they replace all the vacuum lines. Then about 30000 miles later (when the warranty was no more) hissing again! Brought it back to the same dealer and they replaced all the lines again free (because it wasn't fixed right the first 2 times). So far no hissing noise, but I'm not holding my breath.

    Was the grinding noise behind the dash intermittent? We have that too but our dealer couldn't reproduce it because it only does it occasionally.

    I have '02 ZR2 with 77,000 miles on it.

    Problem #1 Just recently the power driver side window goes down just fine but has an extremely difficult time closing. Sometimes you press the button to close it and nothing happens. Other times it goes up very slow. Any suggestions?

    Problem # 2 The truck was in 4 wheel drive low then begin making an awful grinding noise. The only thing that would make it stop grinding was turning the car off. Then when it was restarted the truck won't even attempt to put it in 4W high or low.

    And just for kicks the handle to the 3rd door broke on us last weekend when we were moving. Couple this with air controller hissing problem in which the dealer replaces the vacuum lines twice. This makes me never want to buy another chevy again, especially when we have a 95 Nissan 240SX with 220,000 miles on it and the only thing we've had to do on it other than maintainence is change the starter.

    Could also be that your egr is stuck open,,, Checking for fuel from injectors can be done by looking down the throttle body while you crank it using a remote starter switch,, there is a way to jumper a wire on the aldl to get the pump to cycle as well,, Do you hear the pump cycle when you turn on the key? Is there a schraeder valve to check the pressure? Hope this helps,

    I also have a 98 S-10 with only 120,000 miles. Wouldn't start last month. We replaced the fuel filter module in the fuse box (it was burnt on one side).
    2 days ago: it would not start - again. We replaced the module a second time thinking something electrical was shorting them out. Still wouldn't start.
    Yesterday: Had it towed to the garage. Still wouldn't start.
    Today: Once they started to hook it up to the scope, it started and has been running every since.

    Your problem sounds very similar to what we are going through with ours.
    Have you discovered what the problem is yet?
    We don't know whether to start with the electrical or the fuel system. :sick:

    I have a 2003 ZR2 got new in May of 2003. Got a cap in Dec 03 and an alarm summer of 04. Purchashed a trailer fall of 04 and have nothing but problems with the passenger side rear blinker not wanting to work. 1st couple of times it was the bulb then the trailer harness on the truck was corrided badley. Now I just don't know. The bulbs I have do work but the blinker still does not want to. Anyone with any suggestions please let me know, for this is getting pretty frustrating.

    Thanks for the tips guys, I've tried the starting fluid, and still there is nothing.... Short of buying a comprsion tester, I think it's not getting compression. Any one want to buy

    Not sure if this helps .... but ...

    I think there is as procedure in your manual to manually dis-engage from 4 low to hi gear ... Perhaps if you try that - it will get you into 4/2 hi for now ...

    Also, there is a TSB on the 3rd door handle ... below ...

    Door (Third) - Hard to Open/Handle Breakage

    File In Section: 08 - Body and Accessories

    Bulletin No.: 02-08-64-007

    Date: March, 2002


    Third Door Hard to Open and/or Handle Breakage
    (Adjust Lock Rods)

    1996-2002 Chevrolet and GMC S/T Extended Cab Pickup Models (S-10, Sonoma)


    Some customers may comment that the third door is hard to open and/or the door handle may be broken.


    The lock rods may be improperly adjusted.


    Adjust the lock rods using the following procedure:

    1. Remove the door trim.

    2. Release both lock rod rods from the lock rod retainers.

    3. Position the upper lock rod first. Refer to arrow in illustration. Position the lock rod in the retainer so that there is 10 to 12 mm (0.39 to 0.47 in) (Approximately 11-12 threads showing) from the end of the lock rod.

    Important :Make sure the upper striker is not bound against the latch. If this happens, you must push the door inboard to release the latch. To correct a bound latch, adjust the striker until the striker is centered with the latch.

    4. Position the lower lock rod in the retainer where it rests, usually 5.0 to 6 mm (0.19 to 0.23 in) of threads from the end of the rod after the upper lock rod is locked in place.

    5. Install the door trim.

    Thanks a lot! I think that is exactly our problem with the door. It was always hard to open until the day it snapped. Once we get the new part we will definitely try that!

    I will check out the manual on the 4W drive low tonight. Is there a way I can search for TSBs myself?
  • canufixitcanufixit Posts: 165

    I posted an earlier message concerning this - so take a look/search. In summary - for about 15 - ~ $19 PER vehicle you can get access to a LOT of the schematics, diagrams, TSB's, recalls, etc., etc. Go to and go the the DIY section ...

    Good Luck !!

    try the relays. There are usually two on the firewall for the fuel pump. If the relay is bad the fuel pump will not engage. You msut replace both relays when you replace them. You can see if they are the problem by jumping them. You can take a wire and put it from one pin to another and it should engage the fuel pump. Without seeing your relays I couldn't tell you which pins though.
  • jake7gjake7g Posts: 4
    also trouble shoot the relays. They may be bad and are preventing the fuel pump from engaging.

    My 95 S10 2.2 will start nicely and idle rather bad, But when i accelerate it starts running really rough and will not accelerate then it will completely shut down making a roaring sound.I noticed the back fuel injector is leaking gas...Can someone help me with this
  • stylesstyles Posts: 1
    Youre problem lies most likley in youre computer. 99+ vortecs used VATS wich makes the truck not start without the correct key. Change youre computer to a 96-97 computer and I bet it starts. You can also have the computer reprogrammed but it costs 300$ or more. You can get a cheap computer from a local junkyard for around 100-200.

    hey, i recently bought an '03 s10 with 5k miles. i go to college in rochester ny, and was wondering how the brakes on the ls 2wd are in the winter. i always assumed the truck had discs in the front and drums in the back, but i'm not sure, i don't have the truck here right now. and if they do have drums, are there any conversions i can buy for the back? how are they in the snow? thx.
  • willi1willi1 Posts: 3
    It runs good at idle for about 10 minutes then reves up high - then dies. Won't start for a couple hours afterward. Code 12 blinks always... reset it and tried again, just blinks 12, nothing else. Sounded like it may be sucking air but can't find a pin hole anywhere. Any other suggestions? Has new wires, plugs, distributer, throttlebody, fuel filter, fuel pickup, oil level is fine, ???? can't figure it out especially with the codes coming back as 12 all the time.

    Thanks again!
  • I have a 97 S-10 2.2 and am also having fuel lick from the back fuel injector. I went and got a new injecter and it filled my cylender up with fuel and started licking fuel from the exauste. We pulled it apart and found the new injecter was staying open and sending fuel into the air intake. Do you have any ideas as to what I need to do or what I can do.

  • goetschgoetsch Posts: 2
    You will need to get a spring compressor for the door hinge spring and then you can pound the pins out the top goes in from the bottom and the bottom goes in from the top

    Hey I just recently purchased a 1998 S10 ZR2 with 54,000 miles on it, The first weekend I owned it I went mudding! This past weekend I went fishing, I took my truck out on the bench, I pushed the button and it blinked but it didn't engage, I have been looking it over and I can not figure out why it wont engage. I know its all electrical, and vaccum and what not. If anyone has had this problem please inform me! I have had nothing but bad luck with this truck.
  • donprolinedonproline Posts: 1

  • chevy02chevy02 Posts: 19
    Check out message #647 on page 33. I think that's the same problem . I had that problem too, although I think the dealer fixed it 40000 miles ago and it went away, but it's doing it again occasionally. Perhaps its time for a new valve again...
