Tired of Unpredictable Electrical Gremlins in Your GM Truck?

An Expert’s Tip: The Grounding Gremlin
“Over my 20 years under the hood, I’ve seen countless GMT900 platform trucks (like your Sierra or Silverado) come in with classic BCM failure symptoms. But sometimes, the root cause is a poor ground. Specifically, the main BCM ground located behind the driver’s side kick panel can become corroded or loose. Before you install your new 2011 Sierra 2500 body control module, take five extra minutes to locate that ground point. Unscrew it, clean the contact surfaces with a wire brush until they’re shiny, and re-tighten it securely. This simple step ensures your new module has a perfect connection and prevents a bad ground from damaging it in the future.”
