Before condemning your BCM, always perform a thorough check of the main ground connections, especially the one located near the BCM under the driver’s side dash. A loose or corroded ground is a common culprit for many BCM-related symptoms and can cause a new module to fail prematurely. A simple check can save you time and money.
