End Your Electrical Frustrations Today
Are you chasing down bizarre electrical problems in your GMC Yukon XL? One minute the power windows work, the next they don’t. Maybe your HVAC controls have a mind of their own, or you’re staring at a persistent airbag light. As a technician with over two decades of diagnostic experience, I’ve seen these exact issues hundreds of time, and they almost always point to a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and annoying problems. This isn’t just an inconvenience; it can affect vehicle safety and security.
This replacement Body Control Module, part number 15137395, is the definitive solution for your 2003-2006 Yukon XL BCM issues. We take the guesswork and extra cost out of the repair by pre-programming the module to your vehicle’s specific VIN. This means no expensive trip to the dealership for programming. It arrives at your door ready for a simple, plug-and-play installation, restoring full functionality and peace of mind.
Case Study: A Tricky Diagnosis
A customer brought in their ’05 Yukon XL 1500 with a strange list of complaints: the radio would cut out on bumpy roads, the driver’s side door lock wouldn’t respond to the fob, and the A/C blower was intermittent. They’d already replaced the blower motor resistor with no luck. A quick scan showed a slew of communication DTCs. Instead of chasing each symptom individually, my experience pointed straight to the BCM. A failing solder joint or internal capacitor in the original BCM can cause these exact kinds of erratic, seemingly unrelated failures. We installed a VIN-programmed module, and in less than 10 minutes, every single issue was resolved. This is a classic example of how a single component can be the root of multiple problems.
Is Your Yukon Showing These BCM Failure Signs?
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ HVAC system problems, such as a blower motor that won’t turn on or won’t switch speeds.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Vehicle security system malfunctions, including false alarms or a no-start condition due to the anti-theft system.
- ✔ Erratic behavior from windshield wipers or other electronic accessories.
- ✔ Communication errors with other modules on the vehicle’s data network.
A Straightforward Guide to Installation
You don’t need to be a master mechanic to replace your 2003-2006 Yukon XL BCM. The process is simple and typically takes just a few 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 vehicle’s systems.
- Locate the BCM: In most 2003-2006 Yukon XL models, the BCM is conveniently located under the driver’s side dashboard, near the steering column. It’s a black box with several multi-pin electrical connectors.
- Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have release tabs that need to be pressed. Once disconnected, remove the old module from its mounting bracket and install the new one in its place.
- Connect and Test: Securely plug the connectors into your new, pre-programmed BCM. Reconnect the battery terminal. Start the vehicle and test all functions—windows, locks, lights, HVAC, and wipers—to confirm the repair was successful.
Post-Installation Note: In some cases, an airbag light may persist. This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. Similarly, a brake pedal position relearn might be needed. For your convenience, there is no core charge on this part; you can keep or discard your old module.

Frequently Asked Questions
What is the main benefit of this BCM being VIN-programmed?
VIN programming ensures the module is a true plug-and-play solution. It’s configured with your vehicle’s specific options and software before it ships, eliminating the need for a costly and time-consuming programming session at a dealership.
Do I need any special tools for installation?
No, typically you only need basic hand tools to access the module under the dash, such as a socket or a trim removal tool. The electrical connectors unplug by hand.
Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a very common cause of DTC B1001. Replacing it with this module should resolve the code. However, if the light remains on after installation, the BCM and Sensing and Diagnostic Module (SDM) may need to be synced using a professional scan tool.
Is there a core charge for my old part?
No, there is absolutely no core charge. You are not required to send your old BCM back to us, which simplifies the process for you.
What if I have issues after installing the new module?
Our modules are backed by a one-year warranty and expert support. If you encounter any issues, please contact us. Often, a simple procedure like a battery disconnect/reconnect or clearing old codes can resolve minor hiccups. We’re here to help ensure your repair is successful.
