Is Your GM Truck or Van Acting Possessed?
Are you dealing with a frustrating storm of electrical gremlins in your Silverado, Sierra, Express, or Savana? Flickering dash lights, power windows with a mind of their own, a security light that won’t turn off, or even a no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s body electronics, when the BCM goes bad, it can cause widespread and confusing problems.
From the Shop Floor: “Just last month, a 2006 Silverado 2500 was towed in. The owner had replaced the battery and alternator, but the truck would randomly refuse to start, and the radio and interior lights would flicker erratically. After hooking up the scanner, we found communication loss codes pointing directly to the BCM. Water intrusion from a leaky windshield seal had corroded the main connector—a common issue I’ve seen on over a hundred of these trucks. A new, properly programmed BCM had it running perfectly in under an hour. Don’t chase ghosts; a faulty BCM is often the source.”

Simple Installation to Get You Back on the Road
Replacing the BCM is a straightforward job for a DIYer with basic tools. While locations vary slightly, the process is generally the same.
- Safety First: Always disconnect the negative terminal on your vehicle’s battery before starting any electrical work.
- Locate the BCM: On Silverado and Sierra pickups, it’s typically found under the driver’s side of the dashboard, near the steering column. On Express and Savana vans, it’s usually behind the center dash panel.
- Swap the Module: Carefully unplug the electrical connectors and unbolt the old BCM. Secure the new module in its place and firmly reconnect all connectors.
- Reconnect Power: Re-attach the negative battery terminal.
Important Final Steps: Post-Installation Procedures
To ensure 100% proper operation and safety, a couple of final steps are required after installing your new 2003-2007 GM BCM. These procedures require a professional-grade diagnostic scan tool.
- Airbag System Reset: If the airbag warning light is on, you must perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the BCM and the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Sensor Relearn: Some vehicles may require a recalibration of the brake pedal position sensor. This ensures the brake lights and stability control systems function correctly with the new module.
Note: If you are not comfortable performing these steps, we recommend seeking assistance from a qualified local mechanic.
