Restore Full Control Over Your SUV’s Electronics
Are you battling strange and frustrating electrical issues in your GMC Yukon XL? One moment the power windows work, the next they don’t. Maybe your HVAC blower motor has a mind of its own, or you’re dealing with a persistent security light and a no-start condition. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). This module is the electronic brain for your vehicle’s comfort and convenience features. When it fails, it can make your reliable SUV feel unpredictable. This VIN-programmed BCM, part number 15137394, is the direct-fit, hassle-free solution to restore order and get your vehicle’s systems communicating correctly again.
Is Your Yukon XL Showing These Electrical Gremlins?
- ✔ Unresponsive or erratic power windows, door locks, or interior lights.
- ✔ HVAC system failures, such as a blower that won’t turn on or stays stuck on high.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Security system malfunctions that can prevent the engine from starting.
- ✔ Non-functional windshield wipers or washers.
- ✔ A dashboard that seems to have a life of its own with flickering warning lights.
A Straightforward Guide to Installation
Getting your Yukon back to normal is easier than you think. This is a job most DIYers can handle in their driveway in about 5 minutes.
- 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 system.
- Locate the BCM: On most 2003-2006 Yukon XL 1500 models, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black box with several multi-pin connectors.
- Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have release tabs that need to be pressed. Once disconnected, unclip the old module from its mounting bracket and clip the new one into place.
- Reconnect and Test: Re-attach the electrical connectors to your new, VIN-programmed BCM. Ensure they click securely into place. Reconnect the battery terminal.
- Final Checks: Start the vehicle and test all functions—lights, locks, windows, wipers, and HVAC—to confirm the repair. Note that in some cases, a post-installation procedure may be needed.

- Frequently Asked Questions
- What does ‘VIN Programmed’ mean for me?
It means this BCM arrives ready for installation. We flash the module with your vehicle’s specific Vehicle Identification Number (VIN) and the latest GM software before shipping. This ensures it communicates perfectly with your vehicle’s other computers, saving you a trip to the dealership for expensive programming.
- Do I need any special tools to install this?
No special tools are required for the physical installation. However, please be aware of the post-install procedures. If your airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag system.
- What if my brake lights or traction control act up after installation?
Some models may require a ‘Brake Pedal Position Relearn’ procedure. This is a simple recalibration that can be done with a capable bidirectional scan tool to ensure everything functions as it should.
- Is there a core charge for my old part?
Absolutely not. There is no core charge on this BCM. You can keep your old part without any hassle or need to send it back.
