If you’re dealing with baffling electrical issues in your GMC Yukon XL 2500, you’re not alone. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable truck into a source of daily frustration. This isn’t just an inconvenience; it’s a matter of safety and functionality. This VIN-programmed BCM, part number 10367690, is the definitive, hassle-free solution to restore your vehicle’s core electronic systems to perfect working order.
The BCM is the central command for your truck’s body electronics. When it starts to fail, you’ll notice a cascade of strange problems—from your air conditioning acting up to your power locks having a mind of their own. We eliminate the guesswork and the costly trip to the dealership. By pre-programming this module to your vehicle’s specific VIN, we deliver a part that is truly plug-and-play. You can get your truck back to 100% without needing expensive diagnostic tools for programming.
A Technician’s Notebook: The Case of the Ghostly Glitches
I remember a 2005 Sierra 2500 that came into the shop with a list of complaints that seemed unrelated. The radio would randomly shut off, the driver’s side window worked intermittently, and the security light would flash, sometimes causing a no-start condition. The owner had already replaced the battery and checked all the fuses. After connecting my scanner, I saw multiple communication DTCs pointing to the BCM. A faulty ground trace inside the original module was the culprit. Installing a new, programmed BCM like this one resolved all issues in under 10 minutes. It’s a common failure point I’ve diagnosed hundreds of times on these GM platforms.
Is Your Yukon Exhibiting These Electrical Faults?
A failing BCM often sends out clear warning signs. If you’re experiencing any of the following, a faulty module is the most likely cause. This replacement 2003-2006 Yukon XL 2500 BCM is designed to correct these exact problems.
- ✔ Non-functional or erratic power windows, door locks, or interior lights.
- ✔ HVAC and climate control systems that won’t turn on or operate correctly.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Security system malfunctions, including random alarm activation or a no-start condition where the engine won’t crank.
- ✔ Intermittent operation of windshield wipers or exterior lighting.
- ✔ A dashboard that seems to have a life of its own with flickering warning lights.
Your 5-Minute BCM Installation Guide
One of the best features of our programmed modules is the simple, straightforward installation process. You don’t need to be a professional mechanic to get this done right in your own driveway.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents short circuits and helps reset the vehicle’s systems.
- Locate the BCM: On most GM trucks and SUVs like the Yukon, the BCM is located under the driver’s side dashboard, to the left of the steering column. It’s a black box with several multi-pin connectors.
- Swap the Module: Carefully unplug the wiring harnesses from your old BCM. They have release tabs that need to be pressed. Once disconnected, remove the old module and snap the new one into place.
- Reconnect and Test: Securely plug the wiring harnesses into your new BCM. Reconnect the battery terminal. Start the vehicle and test all functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
Post-Installation Note: In some cases, an airbag light may persist. This requires a professional scan tool to perform the “Setup SDM Primary Key in BCM” procedure. This is a simple sync, not a full programming session. Additionally, some models may require a Brake Pedal Position sensor relearn. There is no core charge for this part, so you can keep your old one without any hassle.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and all related factory software onto the module before we ship it. This ensures it communicates perfectly with your truck’s other computers (like the ECU and TCM) right out of the box, avoiding the need for a dealership visit.
Do I need to send my old part back? Is there a core charge?
No. We do not require a core return for this Body Control Module. You can keep your old part or dispose of it, making the process simpler and faster for you.
Why is my airbag light still on after installation?
The BCM and the Sensing and Diagnostic Module (SDM, or airbag computer) have a security handshake. If the light is on, it just means they need to be re-introduced. A garage with a bi-directional scan tool can perform the ‘Setup SDM Primary Key’ procedure in a few minutes to resolve this.
Is this a difficult part for a DIYer to install?
Not at all. The physical installation is one of the easiest module replacements you can do. It typically takes less than 10 minutes and only requires basic hand tools to access the dashboard panel. The ‘plug-and-play’ nature of our programming saves you the most difficult step.
What other part numbers does this BCM replace?
This module is a direct replacement for numerous part numbers, including 10367690, 15116066, 15136225, 15136877, 15198116, 15257043, and many more. It’s designed for broad compatibility across the GM truck and SUV platform of this era.
