Restore Your GM’s Electrical System with a Reliable BCM Solution
Are you battling bizarre electrical issues in your 2010 GMC Yukon or another compatible GM vehicle? Intermittent power windows, flickering lights, a security system that acts up, or even a frustrating no-start condition can often be traced back to one component: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, when the BCM falters, it can create a cascade of confusing and annoying problems. This isn’t just an inconvenience; it can affect vehicle safety and security.
This listing is for a replacement Body Control Module, part number 20864767, that offers a direct and dependable fix. The best part? Our unique Cloning Service eliminates the need for expensive dealership programming. Simply send us your original BCM, and we will transfer all the critical vehicle-specific data to your new module. This ensures that features like your key fobs, security settings, and specific vehicle options work correctly right out of the box. We handle the technical work so you can get back on the road with confidence.
Case Study: A Tricky Diagnosis
I remember a 2010 Yukon that came into my shop with a laundry list of complaints from the owner. The dome lights would stay on, the driver’s side power window worked only when it wanted to, and the remote start had quit entirely. The customer had already replaced the battery and checked all the fuses. After connecting my scan tool, I found several ‘Lost Communication’ codes (U-codes) pointing to the BCM. Instead of a complete failure, the BCM was failing intermittently, causing these ghost-like problems. By installing a cloned BCM, we restored all functions perfectly without a costly trip to the dealer for programming. It’s a common scenario I’ve seen dozens of times on these GM platforms.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t turn on at all.
- ✔ The security system or alarm randomly activating or preventing the vehicle from starting.
- ✔ Dashboard warning lights appearing for various systems (ABS, Airbag, Traction Control) without a clear cause.
- ✔ Communication error codes, such as U0140, stored in the vehicle’s diagnostic memory.
- ✔ Non-responsive key fobs or remote start features.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most 2010 Yukon models and similar SUVs/trucks, the BCM is located under the steering column, to the left of the brake pedal. For vans and sedans, it’s often behind the center or left side of the dashboard.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- ✔ Install the New Module: Mount the new, cloned BCM in the same position as the old one. Securely plug in all the electrical connectors, ensuring they click into place.
- ✔ Reconnect Power: Re-attach the negative battery terminal.
- ✔ Test and Verify: Start the vehicle and test all body functions: lights, windows, locks, wipers, and radio to ensure everything is operating as expected.
Post-Installation Checks & Procedures
Our cloning service makes this process as simple as possible. However, in some vehicles, certain systems may require a ‘relearn’ or synchronization procedure after the BCM is replaced. This is standard for modern vehicles.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require this procedure to ensure brake lights and stability control systems function correctly.
Please Note: The customer’s original module is always returned with the replacement unit. We do not keep cores. Specific procedures can vary slightly by model. Always consult a factory service manual or a qualified technician if you are unsure.

Frequently Asked Questions
How does the Cloning Service work?
After you place your order, you will ship your original BCM to us. We use specialized equipment to extract the vehicle-specific data and transfer it directly onto the replacement module. This makes the new BCM a true plug-and-play solution, saving you from a trip to the dealership for programming.
Why do you need my VIN?
We use your Vehicle Identification Number (VIN) to access the latest official GM software updates for your specific vehicle. This ensures your replacement BCM is loaded with the most current and stable firmware before we perform the cloning process, correcting potential factory flaws.
Do I need special tools to install this BCM?
For most installations, you will only need basic hand tools like a socket set or screwdriver to access and unbolt the module. The main requirement is being able to comfortably work in the footwell area of your vehicle. No programming tools are needed thanks to our cloning service.
Will my original mileage and key fobs work?
Yes. Because we are cloning your original module’s data, all the vital information, including security programming for your existing keys and the vehicle’s mileage data (where applicable), is transferred to the new unit. Everything will function just as it did before.
What if my airbag light comes on after installation?
This is a possibility and a normal security feature on some GM vehicles. It means the new BCM needs to be electronically ‘introduced’ to the airbag’s Supplemental Deployment Module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
