Restore Full Electrical Function to Your Vehicle
Are you battling bizarre and frustrating electrical issues in your Buick Enclave or another compatible GM vehicle? From flickering dashboard lights and malfunctioning power windows to a security system that has a mind of its own, these are classic signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it falters, it can cause a cascade of seemingly unrelated problems. This replacement Body Control Module, part number 25826124, is the definitive solution to restore order and reliability to your vehicle’s systems.
We take the guesswork and complexity out of the repair. Unlike a standard replacement part that requires expensive dealership programming, this module arrives at your door pre-programmed to your specific vehicle. Simply provide us with your Vehicle Identification Number (VIN) during checkout, and our technicians will flash the unit with the latest official GM software and vehicle-specific calibrations. This ensures a seamless installation process, getting you back on the road quickly and confidently.
From the Diagnostic Bay
We once had a 2010 Acadia (which uses the same BCM) come into the shop with a persistent battery drain. The owner had replaced the battery twice and the alternator once, but the vehicle would still be dead after sitting for a day or two. A quick diagnostic check showed that the BCM wasn’t properly entering its ‘sleep mode,’ keeping other modules on the communication network awake all night. This created a parasitic draw that drained the new battery. Instead of chasing phantom electrical draws, we installed a correctly programmed BCM, and the problem was solved instantly. It’s a perfect example of how a faulty BCM can masquerade as a different issue.
Symptoms of a Failing 2008-2012 Enclave BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on, not turning on).
- ✔ Instrument cluster warning lights flickering or illuminating incorrectly.
- ✔ The anti-theft or security system engaging randomly or preventing the car from starting.
- ✔ HVAC (heating and air conditioning) controls not responding.
- ✔ Communication errors when trying to scan the vehicle with a diagnostic tool.
- ✔ Unexplained battery drain while the vehicle is parked.
Installation and Post-Install Considerations
While this module is designed for a straightforward swap, some vehicle systems may require a recalibration procedure after the new BCM is installed. These are standard industry procedures that can be performed with a capable bi-directional scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, it means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure the brake lights and traction control systems function as intended.
Please note: Specific procedures can vary by exact make and model. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic features. This includes power windows, locks, interior lighting, security systems, wipers, and climate controls. It’s the brain for your car’s body electronics.
Is this BCM truly plug-and-play?
Yes, for the most part. We program it to your vehicle’s VIN before shipping, which handles the most difficult part of the installation. In some cases, as noted above, minor relearn procedures like an airbag sync or brake pedal position relearn may be required with a diagnostic tool.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to work correctly.
What if my original part number isn’t 25826124?
That’s okay! This BCM is a compatible replacement for a long list of part numbers. As long as the part number on your original module is included in the list in our description, this BCM will work for your vehicle.
Why is the airbag light on after I installed the BCM?
The airbag light indicates that the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool. This is a standard security and safety measure.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
