Is Your GM Truck or Van Acting Possessed?
If you’re dealing with a frustrating mix of electrical gremlins in your Silverado, Sierra, Express, or Savana, you’re not alone. One day the power windows refuse to work, the next the radio is dead, and then the security light starts flashing, preventing your truck from starting. These aren’t random glitches; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it goes, it can cause chaos.
From the Shop Floor: A Real-World Scenario
“Just last month, a 2005 Silverado 2500 was towed into my bay. The owner had already replaced the battery and the ignition switch, trying to solve an intermittent no-start and a dome light that wouldn’t turn off. After a quick scan, I saw multiple communication codes pointing to the BCM. These modules, especially on trucks, are notorious for failing due to age, heat cycles, and sometimes even moisture wicking down the wiring harness. Replacing the BCM fixed every single one of his issues. This is a repair I’ve done hundreds of times, and it almost always starts with these confusing symptoms.”

Easy Installation Guide
Replacing the BCM is a straightforward job you can do with basic hand tools. Follow these steps for a successful installation.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to discharge.
- Locate the BCM: On Silverado and Sierra pickups, it’s typically located 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.
- Expert Pro Tip: Before disconnecting the old module, take a close look at the connectors and wiring. Over the years, I’ve seen many BCM issues caused by corrosion on the connector pins from a minor water leak. Clean the vehicle-side harness connectors with a quality electronic cleaner before plugging in your new module.
- Swap the Modules: Carefully unplug the electrical connectors and remove any mounting bolts or clips holding the old BCM. Install the new module in its place and securely reconnect all plugs.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Relearns: Follow the post-installation procedures noted below to ensure all systems are communicating correctly.
Important Post-Installation Steps
To finalize the installation and ensure 100% functionality, a couple of additional procedures are required. This is normal for any BCM replacement and ensures safety systems are properly synced.
- Airbag System (SRS): The airbag warning light will likely be on after installation. You must perform the ‘Setup SDM Primary Key in BCM’ procedure using a bi-directional scan tool. This syncs the new BCM with the airbag module.
- Brake Pedal Position Sensor: Some vehicles may require a brake pedal position sensor recalibration. This ensures the brake lights and stability control systems function correctly.
If you are not comfortable with these steps, we recommend seeking assistance from a qualified local technician.
