Restore Full Control Over Your Yukon’s Electronics
Are you chasing down bizarre electrical issues in your 2003-2006 GMC Yukon XL 2500? One minute the power windows work, the next they don’t. The HVAC system has a mind of its own, and a persistent airbag light is on the dash. As a technician with over two decades of experience, I’ve seen these exact frustrations countless times. The culprit is often a failing Body Control Module (BCM)—the central command center for your vehicle’s comfort and convenience features. This replacement BCM, part number 15137393, is the definitive solution to restore your truck’s functionality and your peace of mind.
What makes our service unique is the included Cloning Service. Instead of shipping you a blank module that requires an expensive trip to the dealership for programming, we transfer the critical data from your original BCM to this replacement unit. This makes the installation a true plug-and-play process, preserving all your vehicle’s specific settings and options. You get a reliable, fully functional module without the dealership hassle or cost.
Is Your Yukon XL Showing These Electrical Gremlins?
- ✔ Unresponsive or erratic power windows, door locks, or interior lights.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ The security system preventing the vehicle from starting (no-start condition).
- ✔ An illuminated airbag warning light, often with a DTC like B1001 (Option Configuration Error).
- ✔ Intermittent failure of windshield wipers or other accessory circuits.
- ✔ A cluster of seemingly unrelated body-related diagnostic trouble codes (DTCs).
From the Diagnostic Bay: The Case of the Haunted Suburban
A customer brought in a 2005 Suburban (which uses the same BCM platform as your Yukon XL) with a laundry list of complaints: the radio would cut out, the driver’s side window was dead, and the security light would flash randomly, sometimes causing a no-start. He had already replaced the battery and checked all the fuses. After connecting my scan tool, I found multiple communication loss codes with the BCM. Instead of a dozen separate problems, it was one failing module causing system-wide chaos. By installing a cloned BCM, we solved every single issue in under 15 minutes. This is a classic example of how a single 2003-2006 Yukon XL 2500 BCM failure can mimic multiple part failures, making it a tricky diagnosis for the unprepared.
Your Straightforward Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning work.
- ✔ Locate the BCM: On your Yukon XL 2500, the BCM is typically found under the driver’s side of the dashboard, near the steering column.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs, so be gentle. Once disconnected, unclip or unbolt the module from its mounting bracket.
- ✔ Install the New Module: Seat your new, pre-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- ✔ Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions: lights, locks, windows, wipers, and HVAC to confirm the repair was successful.
Post-Installation Notes
Thanks to our cloning service, most installations require no further steps. However, in some cases, you may need a professional scan tool for special procedures. If your airbag light remains on, a technician will need to perform the “Setup SDM Primary Key in BCM” function. Additionally, some models may benefit from a “Brake Pedal Position Relearn” to ensure perfect system calibration. These are exceptions, not the rule, but we believe in providing all the information for a successful repair.

Frequently Asked Questions
How does the Cloning Service work?
After you place your order, we’ll provide instructions for sending us your original BCM. Our technicians will extract the unique vehicle data and transfer it to your new module. We then ship both your original and the ready-to-install replacement back to you. This ensures 100% compatibility.
Do I need to return my old BCM as a core?
No, there is no core charge. Your original module is required for the cloning process, but it will be returned to you along with the programmed replacement. You are not buying a repaired part; you are getting a quality replacement part programmed with your vehicle’s data.
Why is my airbag light still on after installation?
This can happen if the BCM and the Sensing and Diagnostic Module (SDM) lose their sync. A professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to re-establish communication and turn off the light. This is a simple procedure for any qualified shop.
Is this something I can install myself?
Absolutely. For anyone comfortable working under the dashboard, the physical swap is very simple and typically takes less than 15 minutes. Our cloning service eliminates the need for computer programming, making this a very DIY-friendly repair.
What if I have a different part number?
This module is compatible with a wide range of part numbers like 15116066, 15136225, 15136877, etc. Please check the full interchange list on this page or contact our expert support team with your VIN and original part number to confirm fitment.
