Restore Your GM’s Electrical Systems with a Plug-and-Play BCM
Are you battling a storm of baffling electrical problems in your 2010 GMC Yukon XL 1500? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or even a vehicle that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of daily frustration. It’s the central command for your vehicle’s comfort and convenience features, and when it fails, chaos ensues.
This isn’t just a replacement part; it’s a direct solution. We offer a genuine GM Body Control Module, part number 20864767, that arrives at your door pre-programmed to your vehicle’s specific VIN. This crucial step means you can bypass the expensive trip to the dealership for programming. Simply provide us with your VIN after purchase, and our experts will flash the module with the latest GM software, ensuring it communicates flawlessly with your Yukon’s existing systems right out of the box.
Case Study: A Tricky Diagnosis
I remember a 2010 Yukon XL 1500 that came into my bay with a complaint of the radio turning on and off randomly and the power locks working intermittently. The customer had already replaced the battery and checked all the fuses. A scan revealed a slew of communication codes, primarily a U0140 (Lost Communication With Body Control Module). Instead of just throwing parts at it, we checked the power and ground circuits to the BCM, which were solid. This confirmed the BCM itself was failing internally. Installing a pre-programmed 2010 Yukon XL 1500 BCM like this one resolved all the ghost-like issues in under an hour, saving the customer significant diagnostic time and money.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior/exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security or anti-theft system preventing the engine from starting.
- ✔ The instrument cluster displaying warning lights or incorrect information.
- ✔ Diagnostic trouble codes (DTCs) such as U0140, U0155, or various B-series codes related to body components.
- ✔ Unresponsive key fob or remote entry functions.
A Straightforward Guide to Installation
Replacing the BCM is a manageable job for a confident DIYer. The module is typically located under the steering column on the driver’s side.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On your Yukon XL, you’ll find the BCM mounted under the driver’s side of the dashboard, often near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. 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 your new, pre-programmed BCM in the same location and securely re-attach the electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Re-install any panels you removed, then reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting) and test functions like lights, locks, and windows.
Important Post-Installation Note: In some cases, additional steps may be required. For example, 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. Always consult a service manual or a professional if you encounter issues.

Frequently Asked Questions
Do I need to send my old BCM back?
No, there is absolutely no core charge for this module. You can keep your original part.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is straightforward. The main benefit here is that our pre-programming service eliminates the most difficult step, which is the software configuration.
What information do you need from me?
After you place your order, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN) to program the module correctly before shipping.
What if my airbag light comes on after installation?
This can happen. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure with a professional-grade scan tool.
Will this fix my specific problem?
This part is the solution for a faulty BCM. While the symptoms listed are common indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause of your issues before ordering.
