Chevy Silverado and GMC Sierra 4x4 Questions



  • ldl3ldl3 Posts: 5

    Still not solved. Local mechanic with top-of-the-line code reader/scanner could find no trouble codes. Chilton's manual is no help either, though it gives a good description of how the 4wd system is supposed to work. I'm hesitant to start replacing components in a hit or miss fashion. Can anyone offer advice?

    Look in the engine bay fuse box find the fuse called Etc if your truck does not have the Atc fuse like mine doesn't. I replaced the 4 wd selector switch on Amazon for 30 bucks as mine was bad. Then I looked for the ATC (automatic transfer case) fuse but couldn't find it I then found ETC fuse (electronic transfer case) pulled it and sure enough it was blown. Replaced it got iny truck started it up and all my lights were back on (on the 4wd selector switch) I found I was in 4hi. Put truck in neutral Pushed 2hi and bam it changed then tried all settings out works like it used to good luck
  • Hi, I have a 2008 Gmc sierra 1500. My 4 wheel indicator keeps activating while I'm driving. It is quickly followed by a grinding noise that sounds as if my truck is trying to engage the 4 wheel. I stop and place my tuck into 4 wheel and out (using the manual lever on the floor of my truck) then the noise stops but the light stays lite. I've checked my fluids and can't seem to figure out why its doing this. Any help would be greatly appreciated before I start tearing into things.
  • I took my 2000 Silverado Z71 to get my brake lines replace because they rusted and broke while I was driving. Anyway it looks like they change my master cylinder too, and it looks smaller than the one I had, is this ok
  • I have a problem with a 2000 Chevy Silverado 2500 6.0l . The service 4wd light came on so I hooked up my scanner to it and it gave a code C0323 after I had replaced the encoder motor. I have been searching for a wiring problem but have yet to find one. it will not shift into any gear. How can I tell if my shift module is bad?? or could it be another problem?
  • I have a 2003 Chevy Silverado 4x4 and the front tires seem like they are hoping when I'm turning. This is happening while it's in 2wd. I've taken it to several mechanics and they have no idea why this is happening. I did get the service 4wd alert a couple times before, but it never stayed on. I've had the front end aligned. I am at a loss right now and have no idea what to do at this point.
