Restore Full Electronic Functionality to Your GM Vehicle
Are you experiencing frustrating electrical problems in your 2007-2012 GMC Acadia? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often traced back to a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent symptoms. This replacement Body Control Module, part number 20864768, is the definitive solution to get your vehicle back in perfect working order.
The most critical step in this process is providing your vehicle’s 17-digit VIN (Vehicle Identification Number) after purchase. We use your VIN to flash the module with the latest, most stable software directly from GM. This ensures the BCM is perfectly matched to your Acadia’s specific options and prevents the compatibility headaches and expensive dealer programming that come with a generic, unprogrammed module.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system engaging randomly or preventing the car from starting.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ “Service Stability System” or other warning messages appearing on the dash.
- ✔ A/C and climate control functions not responding correctly.
- ✔ Communication loss with other vehicle modules, leading to multiple diagnostic trouble codes.
Why Choose Our Programmed 2007-2012 Acadia BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We handle the complex programming for you, saving you time, money, and a trip to the dealership. Simply install the module, and in most cases, your vehicle’s primary functions will be immediately restored. For certain systems, simple relearn procedures may be required.
Post-Installation Procedures:
While this module is designed for a straightforward installation, some vehicle systems may need to be re-synced after the BCM is replaced. This is normal. Key procedures can include:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn might be necessary.

Frequently Asked Questions
What does the BCM do on my 2007-2012 GMC Acadia?
The Body Control Module (BCM) acts as the brain for your vehicle’s electronic accessories. It controls functions like power windows, door locks, interior/exterior lighting, the security system, and climate controls.
Do I need to have a dealer program this BCM?
No. We pre-program the module to your vehicle’s specific VIN before shipping it to you. This eliminates the need for expensive dealership programming.
What if my airbag light is on after I install the new BCM?
This is a common occurrence. The new BCM needs to be electronically introduced to the airbag system (SDM). A qualified technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this part truly plug-and-play?
Yes, for the vast majority of functions. Because it is programmed to your VIN, it will work upon installation. However, as noted, some systems like the airbag or brake pedal position sensor may require a simple ‘relearn’ procedure to fully sync with the new module.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your order until we receive this information, as it is essential for programming.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module.
