Restore Full Function to Your GM Truck or Van
Are you battling strange electrical gremlins in your Silverado, Sierra, or Express van? Flickering lights, power windows with a mind of their own, or a security system that randomly prevents you from starting the engine are all classic signs of a failing Body Control Module (BCM). This vital component is the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and unpredictable problems.

- The security or anti-theft system light is illuminated, causing a no-start condition.
- Erratic behavior from the horn, wipers, or radio.
- Diagnostic Trouble Codes (DTCs) related to communication errors with other modules.

Expert Insight: The Importance of VIN Programming
Think of the BCM as the traffic controller for your truck’s comfort and convenience features. It communicates with dozens of sensors and switches, from your door latch to your headlight switch. Each vehicle has a unique combination of options (RPO codes) stored in the BCM. Simply swapping a module from another vehicle, even an identical one, will cause features to work incorrectly or not at all. Our VIN-specific programming ensures the BCM knows exactly which options your truck was built with, making the installation process as smooth as possible and guaranteeing correct operation from the start.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and vehicle-specific options (like power windows, keyless entry, etc.) that your truck or van came with from the factory. This step is essential for a true plug-and-play installation and prevents compatibility issues.
Where is the BCM located on these vehicles?
On most Silverado and Sierra pickups covered by this part, the BCM is located under the driver’s side of the dashboard, near the steering column. On Express and Savana vans, it is typically found behind the center dash area. Always disconnect the battery before attempting removal or installation.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). This is a security feature. If the airbag light is on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any qualified technician.
Is this a difficult part to install?
For someone with moderate mechanical experience, the physical installation is straightforward. It involves removing a few dash panels and disconnecting electrical connectors. The most critical part is the programming, which we handle for you before shipping. Please review the potential post-installation procedures mentioned in our listing.
Do I need to return my old BCM?
No. This BCM is sold without a core charge. You can keep, recycle, or dispose of your original module at your convenience, simplifying the repair process for you.
