    2007 4.2L Chevy Trailblazer Recently after a bit of a cold snap I noticed I was no longer charging the battery. After the usual diagnostics I replaced the alternator with a used one.

    Need help on this one. My '05 Trailblazer 4.2L I6 has started to show a faint battery light on before ever inserting the key into the ignition.

    Ok, kinda an odd problem. My diagnostics jack under the dash of my '06 TB LT not only shows no codes, but does not power up the code reader. I get the random traction control failure, so there should be something. Is it possible for the car to run with a dead or bad computer? Second...

    Hi everybody, I need some help asap. My battery went out last January in a remote place and I had Walmart replace it. The genius over-tightened the positive terminal and it loosened over time(stripped threads) allowing corrosion to set in. A couple days ago, the terminal finally went...

    I have a bad cell in my battery and need to replace it. Which battery do you suggest to get? I don't want to over pay for a high end battery that isn't worth it, or buy a cheap battery that wont last long or work well.
