  1. 4x4 Drivetrain
    Hello, I have this problem I think. It is winter now, so I have started to use my four wheel drive. Last year the system seemed tohave an issue that it would engage 4x4 on its own in parking lots and slowing to stop signs. I read that you could pull the fuse and reset the system, so I did, and...

    Today while driving down the freeway, the traction control light started blinking (slippery when wet sign) and it felt like one or more of the brakes started pulsating (feeling like from the rear). The TC light immediately went back off. This happened several times during the drive home. Also...
  3. 4x4 Drivetrain
    Hi all, I am a first time poster, but need some help. I have scoured the threads and have not found my exact issue. Since I bought the vehicle the 4WD selector switch has been dark and I have never had an indicator light on the dash. I tried pulling #8 under the hood, but it did not help. I...

  5. 4x4 Drivetrain
    Hi, I'm looking for some help on fixing a problem with my '06 tb 5.3L 4wd (90k miles). I've gone through the site quite extensively but I don't think anyone has had the exact same problem (and posted the solution), so please excuse the long post but I wanted to put up all of the details...

  7. Off-Road
    Been doing some off roading in my newly aquired trailblazer and i am unsure of which setting to use when doing a steep hill climb with about an inch covering of snow. I usually use 4lo but ive had trouble where the only tire that spins is the one with the least traction. I need all the other...

    I have a 05 Trailblazer LT with 4x4. I have used the 4x4 successfully in the past. A few days ago I tried to switch it into 4low to get over a tall curb with a trailer, and the instant I switched it the indicator lights went from being active to not light up at all in any selection. At the same...

  10. 4x4 Drivetrain
    Although I thought I'd be able to add this to an existing thread, but none appear to be quite the same - I'd be hijacking someone else's thread instead of adding useful info - so here goes with a new thread. Hopefully this will be useful to someone else down the road. 2004 GMC Envoy XUV with...
  11. OEM Issues
    I have a 2005 TB LT 4WD - so I am driving Sunday Night and the Airbag light came on and has been on since. I work for a used car dealer and I went and got the reader for the codes and hooked it up. ( I have done this before bc I had a generic cold air intake and it triggered the Service Engine...
  12. 4x4 Drivetrain
    So it seems that every month so far this year has plagued me with some kind of financial "incident". Yesterday I had taken some stuff over to a good friend of mine's house. I had to 4wd backwards into his yard to get over a curb. Later on I left his house and noticed a noise coming from the...
  13. Suspension
    So I just bought a set of springs and struts for my 05 xl denali 4wd. My question is how much can i lower this before I have to worry about angle issues affecting my balljoints and tire wear. I will be having an alighnment done right after I install it to correct as much as posible...

    I have an '04 Blazer with the Vortec 4.3 I6. ~73K miles. Service: Oil changes only. I've used Auto 4WD several times over the past few months. Every so often, the 4WD light on the dash blinks once for just a split second, then goes away for weeks. Just recently, with 4 inches of snow on...
  16. 4x4 Drivetrain
    When the car is put into 2wd it drives just fine when its put in 4hi it clunks and feels like I'm driving over bumps. I can hear a buzzing noise when I'm switching between 2wd and 4hi but i don't get a little switching jerk forward. I went to an auto shop and lifted the envoy they said its...
