Are you experiencing frustrating electrical problems with your 2008-2012 Buick Enclave? Issues like flickering lights, malfunctioning power windows, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s comfort and convenience features, and when it fails, it can make driving a nightmare. This replacement Body Control Module, part number 20864768, is the definitive solution to restore your vehicle’s full functionality.
This isn’t just a part in a box. We provide a crucial programming service that sets our modules apart. Before we ship your BCM, we will flash it with the latest GM software updates, specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN). This ensures a seamless installation process, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest.
Expert Pro Tip: Before replacing your BCM, take a moment to inspect the main battery ground cable and the BCM’s own ground connection. A loose or corroded ground can mimic the symptoms of a failed module and is a much simpler fix. A quick check with a multimeter can save you time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ The radio or infotainment system randomly shutting off or behaving strangely.
- ✔ False warning lights appearing on the dashboard.
- ✔ Rapid battery drain while the vehicle is off.

Choosing our BCM means you’re getting a reliable, VIN-programmed component that’s ready for installation right out of the box. This module is a direct replacement for a wide range of original part numbers, including 15828601, 20815898, 22860591, and many others, ensuring broad compatibility across numerous GM models like the Acadia, Traverse, and Impala. We take the guesswork out of the repair, providing a part that communicates perfectly with your Enclave’s other electronic systems.
Installation and Post-Install Considerations
While this module is programmed for your vehicle, some models may require simple relearn procedures after installation. For instance, if the airbag warning light illuminates, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control function. These procedures are straightforward for any qualified technician. Best of all, there is no core charge, so you can keep your original module.
Frequently Asked Questions
What does a Body Control Module do on my Buick Enclave?
The BCM acts as the main computer for your vehicle’s body electronics. It controls features like your power windows, door locks, interior/exterior lighting, security system, and wipers, ensuring everything works as intended.
Is this BCM a plug-and-play part?
Almost! We program the module to your vehicle’s VIN before shipping, which handles the most complex part of the installation. This allows it to communicate with your car. Some vehicles may require additional simple ‘relearn’ procedures for systems like the airbags or brake sensor after installation, which can be done by a mechanic.
What do I need to do after I place my order?
After you complete your purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it.
Will this fit vehicles other than the Buick Enclave?
Yes, this BCM is compatible with a wide variety of GM vehicles, including the Chevy Traverse, GMC Acadia, Saturn Outlook, Chevy Impala, and various Express/Savana vans. Please review the detailed fitment list to confirm compatibility with your specific model and year.
What happens if my airbag light is on after I install the BCM?
If the airbag light is on, it means the new BCM needs to be synced with the airbag system’s computer (SDM). A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I have to send my old part back?
No, there is no core charge for this part. You can keep your original BCM.
