Is Your Buick Enclave Experiencing Electrical Gremlins?
If you’re dealing with bizarre and frustrating electrical issues in your 2008-2012 Buick Enclave, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, managing everything from your power windows and door locks to your interior lights and security system. When it starts to fail, it can cause a cascade of seemingly unrelated problems that can be difficult to diagnose.
Expert Pro Tip
Before condemning your BCM, always perform a full battery and charging system test. A weak battery or poor ground connection (especially the main chassis ground) can mimic BCM failure symptoms. Check that battery terminals are clean and tight. This simple check can save you hundreds of dollars in diagnostic time and parts.
Common Symptoms of a Failing 2008-2012 Enclave BCM
A faulty Body Control Module can manifest in numerous ways. If you’re noticing any of the following issues, it’s a strong indicator that your BCM needs replacement:
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on when they should.
- ✔ The vehicle’s security system acting erratically, such as the alarm going off for no reason.
- ✔ The key fob failing to lock or unlock the doors.
- ✔ Warning lights on the dashboard (like the airbag light) illuminating without a clear cause.
- ✔ Radio or climate control systems behaving unpredictably.
- ✔ Communication errors when a diagnostic scan tool is connected.

Don’t let a faulty BCM keep your luxury SUV off the road. This Body Control Module, part number 15880684, is the definitive solution to restore full functionality to your vehicle. We eliminate the biggest hassle of BCM replacement: the programming. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) during checkout, and our technicians will program the module with the latest GM software updates specific to your Enclave. This ensures that when the part arrives, it’s ready for a straightforward installation process, saving you a costly trip to the dealership.
This module is a direct replacement for a wide range of original equipment part numbers, ensuring broad compatibility across many GM models including the GMC Acadia, Chevrolet Traverse, Saturn Outlook, and more. By matching the programming to your VIN, we guarantee it will communicate flawlessly with the other modules in your vehicle.
Installation and Post-Install Procedures
While this module is designed for a direct fit, some vehicles may require additional electronic ‘handshake’ procedures after installation. These are not signs of a defective part but are standard vehicle-specific requirements.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper operation of the brake lights and traction control system.
We always recommend consulting a factory service manual or a qualified automotive technician for specific installation guidance for your vehicle. There is no core charge for this part, so you can keep your original module.
Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before the part is shipped. Just provide your vehicle’s 17-digit VIN when you place your order, and it will arrive ready to be installed.
Where is the BCM located on a 2008-2012 Buick Enclave?
On the Buick Enclave and its sister vehicles (Acadia, Traverse), the BCM is typically located behind the dashboard on the driver’s side, often to the left of the steering column.
What is a VIN and why do you need it?
The VIN is your vehicle’s unique 17-digit identification number. We use it to access the exact factory software and calibration files for your specific vehicle, ensuring the BCM works perfectly with all the options your car was built with.
Will this fix my intermittent electrical problems?
If your issues match the common symptoms listed above and other causes like fuses, relays, and battery connections have been ruled out, a faulty BCM is the most probable cause. Replacing it with our programmed module is the most effective repair.
What if my airbag light comes on after I install the new BCM?
This is a common occurrence. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
