Is your GMC Savana or Express van experiencing bizarre electrical problems? The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating issues, from non-functional power accessories to a vehicle that won’t start. This replacement Body Control Module is the definitive solution to restore your van’s functionality and reliability.
This isn’t just a generic part off the shelf. We program each module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures compatibility with your van’s unique options and systems, loading the latest software updates from GM for optimal performance. This process eliminates the need for expensive programming at a dealership, saving you time and money.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Problems with the radio or climate control systems.
- ✔ A complete no-start condition where the starter doesn’t engage.

Installation and Post-Install Considerations
While installation is straightforward for many, some vehicles may require additional steps to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct operation of the brake lights and stability control systems.
We always recommend consulting a factory service manual or a qualified automotive technician for specific guidance related to your vehicle.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide variety of non-engine related functions. This includes power windows, locks, lights, wipers, the security system, and climate controls.
Why do you need my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the BCM with the exact software and settings for your specific model, year, and options. This ensures the module works correctly right out of the box without needing a trip to the dealer for programming.
Is this part difficult to install?
The physical replacement is typically straightforward, involving disconnecting the battery and swapping the module. However, as noted, some vehicles may require post-installation procedures like an airbag sync or brake sensor relearn, which require a professional diagnostic tool.
What happens if my airbag light is on after installation?
This indicates the new BCM needs to be electronically introduced to the vehicle’s airbag system (SDM). A qualified technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
How do I know for sure that my BCM is the problem?
The best way to be certain is to have a professional diagnosis performed. Common signs include multiple, unrelated electrical issues. A diagnostic scan can often reveal communication fault codes with the BCM, confirming it’s the source of the problem.
