Tired of Chasing Electrical Gremlins in Your GM Truck or Van?
Is your Silverado, Sierra, Express, or Savana acting possessed? Flickering lights, power windows with a mind of their own, a security light that won’t turn off, or even a frustrating no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the nerve center for your vehicle’s body electronics, when the BCM goes bad, it can create a cascade of bizarre and unpredictable problems. Stop throwing parts at the issue and get the direct-fit, reliable solution.

Expert Pro Tip from 20+ Years on the Floor: A very common misdiagnosis I see with these GM trucks is blaming a weak battery for intermittent electrical issues. A customer will replace the battery and alternator, but the problems persist. Often, the root cause is a failing BCM causing a parasitic draw that drains the battery overnight. Before you install your new BCM, take a moment to clean the main connector plugs with a quality electronics cleaner to ensure a perfect, corrosion-free connection.
Simple Installation to Get You Back on the Road
Replacing the BCM is a straightforward job that a confident DIYer can handle. The location varies slightly between trucks and vans.
- Safety First: Always disconnect the negative battery terminal before beginning any electrical work.
- Locate the BCM: In Silverado and Sierra pickups, it’s typically found under the driver’s side of the steering column. In Express and Savana vans, it’s located in the center of the dash.
- Remove Connectors: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed.
- Swap the Module: Unbolt the old BCM and install the new, pre-programmed unit in its place.
- Reconnect Everything: Plug the connectors firmly into the new BCM and reconnect your vehicle’s battery.
CRITICAL: Post-Installation Procedures
After installing your new 2003-2007 GM BCM, a couple of final steps, known as relearn procedures, are required to ensure all systems communicate correctly. These steps typically require a bi-directional scan tool.
- Airbag System (SRS): To clear the airbag warning light, you must perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position: Some vehicles may require a Brake Pedal Position Sensor Calibration to ensure proper brake light function and communication with other systems like cruise control.
Note: If you are not comfortable performing these procedures, we strongly recommend seeking assistance from a qualified technician.
