Is Your Buick Enclave Experiencing Strange Electrical Problems?
The Body Control Module, or BCM, is the central nervous system for your vehicle’s electronic accessories. When it begins to fail in a 2008-2012 Buick Enclave, it can cause a cascade of confusing and frustrating issues. From flickering lights to a car that won’t start, a faulty BCM can make your vehicle unreliable. This replacement Body Control Module, part number 20864767, is the definitive solution to restore your Enclave’s full functionality.
From the Diagnostic Bay
We had a 2011 Enclave come in with the strangest set of symptoms. The customer reported that sometimes the radio would shut off, the power locks would cycle randomly while driving, and the interior lights would stay on, draining the battery overnight. They had already replaced the battery and checked the alternator. After running network diagnostics, we traced all the communication errors back to a single point of failure: the BCM. Once we installed a VIN-programmed module like this one, all the bizarre electrical gremlins vanished instantly. It highlights how a single component can create widespread, seemingly unrelated problems.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from the interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning windshield wipers or horn.
- ✔ Security system faults or a “Service Theft System” message.
- ✔ The vehicle failing to start despite a good battery and starter.
- ✔ False warnings on the instrument cluster.
- ✔ Unresponsive key fob commands.
Why Choose Our 2008-2012 Enclave BCM?
Getting your vehicle back to perfect working order shouldn’t be a hassle. Unlike parts from a dealership, this BCM comes pre-programmed specifically for your vehicle. We use your Vehicle Identification Number (VIN) to load the latest GM software and vehicle-specific calibrations before it even ships. This means no expensive trips to the dealer for programming. It’s a true plug-and-play solution designed to save you time and money.
Installation and Post-Install Notes
Installation is straightforward for those with basic mechanical skills. The BCM is typically located in the driver’s side dash area. After swapping the module, some vehicles may require simple relearn procedures. For instance, if your airbag light is on, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. Similarly, a “Brake Pedal Position Relearn” might be necessary to ensure brake lights and traction control work correctly. Always consult a factory service manual for your specific vehicle.
