Solve Your Yukon’s Frustrating Electrical Problems for Good
Are you dealing with baffling electrical issues in your 2003-2006 GMC Yukon or other compatible GM vehicle? Flickering lights, a dead instrument cluster, power windows with a mind of their own, or an HVAC system that won’t cooperate are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated problems. This OEM-quality replacement module, part number 15137395, is the definitive solution to restore full functionality and peace of mind.
What makes our module different is our expert Cloning Service. Instead of just programming the module with factory data, we transfer the exact configuration from your original BCM to this new unit. This ensures a seamless, 100% plug-and-play installation without the need for expensive dealership programming or complex relearn procedures. It’s the most reliable way to get your truck back to perfect working order.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2005 Yukon XL that came into my bay with a truly ghostly issue. The owner said sometimes the security light would flash and it wouldn’t start, other times the radio and interior lights would go out while driving. He’d already replaced the battery and checked the main grounds. I’ve seen this exact pattern dozens of times. We hooked up the scanner and found a handful of ‘loss of communication’ codes with the BCM. Instead of spending hours chasing phantom electrical draws, we identified the failing BCM. With a cloned replacement, all the strange symptoms disappeared instantly. The customer was thrilled to have his reliable family hauler back without a massive diagnostic bill.
Is Your GM Truck Showing These Symptoms?
- ✔️ Intermittent or non-functional HVAC controls, including the blower motor.
- ✔️ Power windows, door locks, or interior lights not working correctly or at all.
- ✔️ The security system acting up, causing a no-start condition or false alarms.
- ✔️ An illuminated airbag light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔️ Erratic behavior from the dashboard gauges or warning lights.
- ✔️ Communication errors with other modules on the vehicle’s data network.
How Our Hassle-Free Cloning Service Works
Our process is designed for simplicity and accuracy. After you place your order, you’ll send us your original BCM. Our technicians will then perform a precise data transfer, copying all the vehicle-specific settings, key information, and option configurations to your new module. We then ship both your original module and the ready-to-install replacement back to you. This service ensures that the new BCM is a perfect electronic match for your vehicle, preserving all original functionality without any additional steps. Best of all, there is no core charge, and you get to keep your original part.
Your 5-Minute BCM Installation Guide
- ✔ Safety First: Before you begin, disconnect the negative terminal on your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On most GMT800 platform trucks and SUVs like the Yukon, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black plastic box with several large multi-colored connectors.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, the module can be unclipped or unbolted from its bracket.
- ✔ Install the New Module: Seat the new, cloned BCM into the mounting bracket and firmly reconnect all the electrical harnesses. You’ll hear a click as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, radio, and HVAC—to confirm the repair is complete.
Post-Installation Note: In some cases, particularly if the airbag light was on, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. A brake pedal position relearn may also be required on certain models. Always refer to a service manual for vehicle-specific details.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows and locks, security system, wipers, and climate control, ensuring everything works together seamlessly.
What is a “Cloning Service” and why is it better?
Cloning is a process where we transfer the complete software and vehicle-specific data from your old BCM to the new one. This is superior to standard programming because it creates an exact electronic duplicate, ensuring 100% compatibility with your vehicle’s existing options and security system, eliminating the need for a trip to the dealer.
Will I need to have this module programmed by a dealer?
No. Our cloning service makes this module a true plug-and-play part. Once you receive it, you can install it yourself in minutes without any need for additional programming or calibration at a dealership, saving you time and money.
Why do you send my original BCM back to me?
We always return your original part. We believe you paid for it, and it’s yours to keep. This also means there is absolutely no core charge or need to handle core returns.
What if my airbag light turns on after installation?
This is uncommon but can happen. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s Sensing and Diagnostic Module (SDM). A mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
