Restore Full Electronic Functionality to Your Buick Enclave
Are you battling frustrating electrical issues in your 2008-2012 Buick Enclave? Flickering lights, malfunctioning power windows, a dead battery overnight, or strange warning messages on your dash are all common signs of 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 unpredictable problems. This replacement BCM, part number 20815898, is the definitive solution to restore your vehicle’s systems to perfect working order.
We take the guesswork and hassle out of the repair process. Unlike a standard replacement that requires expensive dealership programming, this module arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest GM software updates, ensuring optimal performance and compatibility right out of the box. This plug-and-play solution saves you time, money, and a trip to the dealer.
From the Diagnostic Bay
We had a 2011 GMC Acadia (which shares a platform with the Enclave) come in with a classic case of BCM failure. The customer complained of the radio turning on by itself, interior lights not working, and a persistent ‘Service StabiliTrak’ message. After confirming power and grounds were good, we pinpointed the BCM. Instead of a costly dealer visit, we installed one of our VIN-programmed modules. The installation was straightforward, and after a quick brake pedal position relearn, all the bizarre electrical gremlins were gone. The customer was thrilled to have their reliable family vehicle back without the dealership price tag.
Solving Your Vehicle’s Electrical Problems
A faulty BCM can manifest in numerous ways, often seeming like multiple unrelated issues. By replacing your old module with this pre-programmed unit, you can resolve these common failures and get your vehicle back to its reliable self.
Common Symptoms of a Failing BCM:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from the radio, climate control, or interior/exterior lighting.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ False warning lights on the instrument cluster (e.g., security, airbag, traction control).
- ✔ Remote keyless entry (fob) not working correctly.
- ✔ Horn honking unexpectedly or not working at all.

Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require a simple component relearn procedure after the BCM is installed. These do not require a trip to the dealer and can often be performed with a high-quality bidirectional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn might be necessary.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls functions like power windows, door locks, interior lights, the security system, and the climate control fans, among many others.
Is this part really plug-and-play?
Yes, for the vast majority of functions. Because we program the module to your VIN before shipping, it eliminates the need for expensive dealership programming. In some cases, a simple ‘relearn’ procedure may be needed for specific components like the airbag or brake pedal sensor, as noted in the description.
Where do I provide my VIN?
After you complete your purchase, you will receive an email with instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module until we receive this information.
Will this fix my check engine light?
Generally, the BCM does not control engine functions; that is the job of the Engine Control Module (ECM). A faulty BCM typically causes issues with body electronics, not engine performance. If your primary issue is a check engine light, you may need to diagnose your ECM.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
