    Hello, My batteries need replacing. Strangely, my passenger side battery is in front of fluid reservoir and most of the videos I watched had the battery tray back by the firewall. Not sure what the story is here. Also... my truck will not fit anything larger than the 760 CCA battery size. I...

    I've got an 06 LBZ with cel P0621. I had the batteries and atl tested today and all checked out to be good. No dash light for battery and no message on the odometer for battery not charging. Voltmeter shows 14.1 when the truck is running. Could a bad ground somewhere be causing this? The code...

    Hi all Have a 2016 LML will not start. Drove fine and shut it off and now will not crank. Just hear a click. Some background: Truck is stock with 140000kms. Had a slow crank/start issue for the last little while which I knew was a bad battery. Tired to boost it and still wont crank. Replaced...

    This has been an ongoing issue. It started back in June. I was driving and it lost power and it said service traction control and StabiliTrak. and sometimes whenever I go to crank it will do this and will not crank. So it sat in the shop for a month and they called the dealer and they said it...

    Hey all I just bought a 2007 with plow from my work and it has a battery drain issue that I don't want to tear into til spring is here and plowing season is over. For now I am just planning on putting a disconnect on, but my question is which battery negative do I put it on? Thanks

    Hello Everyone, I am a new member, just took delivery on my 2022 3500HD Denali last week. I ordered the truck with dual alternators thinking that I would have increased current to charge batteries in the RV. However, I think that the RV charging pin is limited to 40 amps by a fuse in the...

    So intermittently my truck will have a huge kick back (like a really rough shift), and then the gauges will go all over the place and my doors will just keep unlocking and locking constantly, my screen/display for my tuner turns off, and sometimes i lose power to the accelerator. After replacing...

    I have a 2015 GMC 2500 with around 90k miles. Last year some work was done on the truck by a local diesel shop (Cp3 Conversion, FASS, up pipes, downpipe, EGR plate, full 4"exhaust, tuning). Ever since then, every time I start the truck, I get a "low battery" message pop on the dash. The shop...
  10. 2001 - 2007 (GMT800) Non Powertrain
    For about 4 weeks, my AC has been giving me problems at an idle. In the past, it would blow nice and cold all through the RPM range. Lately, if at an idle for more than a minute, it would blow that warm, muggy air like the compressor kicked out. I could never see that the clutch disengaged...

    I have an '02 Chevy Silverado 2500HD crew cab plus long bed. Love the truck. My alternator goes out, but I decide to drive from Milpitas to Santa Cruz and back. It's a 2 hr drive round trip and I made alot of stops in between. I know I'm pushing it as the voltage is below 12 volts and the...

    Have a 2002 Silverado 2500 HD with the Duramax. The truck wouldn't start one day, had no power at all. Batteries are under 2 years old. I noticed some corrosion on the at the terminal end of the battery cables so I cleaned them up. Still no power at all. So I went home to get my meter and...
