Restore Full Electrical Control to Your GM Vehicle
Are you battling frustrating and unpredictable electrical problems in your 2008-2012 Buick Enclave or other compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, erratic dashboard warnings, or even a no-start condition often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it falters, it can create a cascade of seemingly unrelated problems that can be difficult to diagnose. This replacement Body Control Module, part number 20935349, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
From the Diagnostic Bay
We had a 2011 GMC Acadia (which uses the same BCM) come into the shop with the strangest issue. The customer said their rear wiper would turn on by itself, and sometimes the radio volume would change randomly. They had already replaced the wiper motor and the radio head unit with no success. After hooking up our diagnostic scanner, we saw multiple communication errors pointing back to the BCM. The internal logic was failing, sending phantom signals across the vehicle’s network. Installing a VIN-programmed BCM like this one solved every single one of their ghost-in-the-machine problems instantly. It’s a reminder that the central controller is often the root cause of widespread, bizarre electrical symptoms.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, 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 flickering, staying on, or not turning on.
- ✔ The security system acting up, causing false alarms or preventing the engine from starting.
- ✔ Dashboard warning lights (like the airbag or ABS light) illuminating for no reason.
- ✔ Wipers or climate control functions behaving erratically.
- ✔ Key fobs that stop working or have a severely limited range.
- ✔ Communication errors with diagnostic scan tools.
Why Choose a Programmed 2008-2012 Enclave BCM?
This is not just a generic, off-the-shelf part. To ensure flawless integration with your vehicle, we program this module specifically to your vehicle’s Vehicle Identification Number (VIN) before shipping. This critical step loads the correct software and vehicle-specific settings, making the installation process as simple as possible. By programming the module for you, we eliminate the need for an expensive trip to the dealership for coding. You receive a part that is truly ready for installation, loaded with the latest software updates from GM for optimal performance and reliability.
Simple Installation Process & Post-Install Requirements
Physically replacing the BCM is generally straightforward, typically located under the dash on the driver’s side. However, after the new module is installed, a few additional steps, known as relearn procedures, may be necessary to ensure all vehicle systems communicate correctly. These are not defects but standard procedures when replacing a major control module.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool must be used to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration. This ensures your brake lights and traction control systems function accurately with the new BCM.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related electronic functions. This includes power windows, door locks, interior and exterior lighting, security systems, wipers, and climate control fans, among other things.
Do I need to program this BCM?
No. We handle the programming for you before the part is shipped. Simply provide us with your vehicle’s VIN during or after checkout, and we will flash the module with the latest GM software specific to your vehicle’s configuration.
Where is the BCM located on a 2008-2012 Buick Enclave?
On the Buick Enclave, GMC Acadia, and Chevy Traverse from this era, the BCM is typically located behind the dashboard on the driver’s side, often to the left of the steering column.
Will I need a special tool for the post-installation procedures?
Yes, for certain procedures like the Airbag System Sync, a professional-grade bidirectional scan tool is required. Many local repair shops have this equipment. Simpler procedures may sometimes be completed without special tools, but it varies by model.
Is there a core charge for my old BCM?
No, there is no core charge for this part. You can keep your original module without needing to send it back.
