Is your 2008-2012 GMC Savana 1500 van experiencing bizarre electrical issues? Flickering lights, malfunctioning power windows, or a security system that acts up on its own are common signs of a failing Body Control Module (BCM).

This replacement BCM, part number 20864768, is the reliable, plug-and-play solution to restore your van’s functionality and peace of mind.
Unlike a standard replacement from a dealership, this module comes pre-programmed to your vehicle’s specific VIN.

Simply provide your VIN after purchase, and we’ll handle the software flashing before it ships. Installation is straightforward, allowing you to get your workhorse vehicle back in service quickly.

Post-Installation Information
While this module is designed for a simple installation, some vehicles may require minor follow-up procedures. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on 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 brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the instrument panel.
Do I need to program this Savana 1500 Body Control Module?
No. We pre-program the module to your vehicle’s VIN before we ship it. This means it’s ready for installation right out of the box, saving you a trip to the dealership.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This is essential for us to program the BCM correctly for your specific vehicle options.
Is this BCM difficult to install?
For most GM vans and trucks, the BCM is located under the driver’s side of the dashboard and is accessible with basic hand tools. It typically involves removing a few trim panels and unplugging the electrical connectors. Most DIY mechanics can perform the swap in under an hour.
What if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
