Restore Your Buick’s Electrical System with a Hassle-Free Solution
Is your 2008-2012 Buick Enclave suffering from strange and unpredictable electrical problems? Flickering lights, unresponsive power windows, a security system that acts up, or even a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating issues. Instead of a costly trip to the dealership for diagnostics and programming, we offer a direct, reliable, and simple solution. This Body Control Module, part number 20815898, is configured specifically for your vehicle using our professional cloning service.
Case Study: A Tricky Diagnosis
I remember a 2011 Enclave that came into my shop with a laundry list of complaints from the owner. The dome lights would stay on, the driver’s side window wouldn’t go down, and the remote key fob worked only intermittently. The owner had already replaced the battery and was told he might need an alternator. After checking the charging system, which was perfectly fine, I hooked up my professional scan tool. It revealed several communication error codes (U-codes), pointing to a network issue. In my 20+ years of experience, when you see multiple, unrelated body electronic failures, the BCM is the first place to look. We confirmed the BCM was the source of the problem. By providing a cloned module, we had the customer back on the road the same day, saving them from a week-long wait and a massive programming bill at the dealer.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution you need:
- ✔ Erratic interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ Power windows, door locks, or mirrors behaving unpredictably or failing completely.
- ✔ The anti-theft or security system light flashing, preventing the car from starting.
- ✔ The key fob no longer working to lock or unlock the doors.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Communication Diagnostic Trouble Codes (DTCs) such as U0100, U0140, or other U-series codes.
- ✔ Intermittent no-start condition where all the lights come on but the engine won’t crank.
How Our Plug-and-Play Cloning Service Works
Forget about towing your vehicle to a dealer. Our cloning service makes this repair straightforward for any DIYer or professional mechanic. The process is simple: after your purchase, you send us your original BCM. We then extract the vehicle-specific data—including key information and option configurations—and transfer it directly to this replacement unit. We then ship both your original module and the ready-to-install replacement back to you. This ensures a seamless installation and perfect communication between the new BCM and your vehicle’s other electronic systems. This is the most reliable way to replace a 2008-2012 Enclave Body Control Module without introducing new problems.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
- ✔ Locate the BCM: On the 2008-2012 Buick Enclave, the Body Control Module is typically located on the left-hand (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Seat the new, programmed BCM into the mounting bracket and secure it. Reconnect all the electrical connectors, ensuring they click firmly into place.
- ✔ Final Steps: Reconnect the negative battery terminal. Start the vehicle and test all functions: windows, locks, lights, and wipers to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play process, some GM vehicles may require simple relearn procedures after the battery has been disconnected or a new module is introduced. These may include:
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions about the 2008-2012 Enclave Body Control Module
What exactly does a Body Control Module do?
The BCM is like the ‘brain’ for your car’s comfort and convenience features. It doesn’t control the engine, but it manages almost everything else: power windows, locks, interior and exterior lighting, wipers, the security system, and more. When it fails, these systems can become erratic.
How does your cloning service work? Is it difficult?
It’s very simple for you. After you order, you’ll ship your original BCM to us. Our technicians will read the unique data from your module and write it onto the replacement unit. We then ship both modules back to you. The replacement is then ready to install without any further programming.
Do I absolutely have to send you my original BCM?
Yes. The cloning process is essential for making the replacement module plug-and-play. Without the data from your original unit, the new BCM won’t have your vehicle’s specific key codes or options, and it will not function correctly without a trip to the dealer for programming.
Will this fix my car’s specific electrical problem?
If your vehicle is exhibiting multiple, seemingly unrelated electrical issues like those listed in the symptoms section, a failing BCM is the most common cause. While we cannot diagnose your vehicle remotely, these symptoms are classic indicators of BCM failure.
What tools are needed for installation?
For most models, including the Buick Enclave, you will only need basic hand tools. This typically includes a socket set or nut driver to remove the lower dash panels and a small screwdriver or trim removal tool. No specialized electronic tools are required for the physical installation.
