Tired of Your Yukon’s Electrical Gremlins?
Are you dealing with a GMC Yukon that seems to have a mind of its own? Flickering lights, unresponsive power windows, a dead HVAC system, or a security light that won’t let your truck start are all classic signs of a failing Body Control Module (BCM). As the central computer for your vehicle’s comfort and convenience features, a faulty BCM can cause a cascade of frustrating and hard-to-diagnose issues. This isn’t just an annoyance; it affects your vehicle’s daily usability and security.
This replacement Body Control Module, part number 15137395, is the definitive solution for your 2003-2006 Yukon BCM problems. We take the guesswork and dealership hassle out of the repair by pre-programming the module to your vehicle’s specific VIN. This ensures that when it arrives, it’s ready for a true plug-and-play installation, restoring full functionality without needing an expensive trip to the dealer for programming.
A Technician’s Notebook: The Haunted Yukon Case
Just last month, a 2005 GMC Yukon was towed into my bay with a no-start condition. The owner was frustrated, explaining that the security light was flashing, the power locks worked intermittently, and the radio would sometimes stay on after he took the key out. He’d already replaced the battery and checked the fuses. After connecting my scanner, I saw a slew of communication codes, including the infamous B1001. In my 20+ years of experience, this pattern almost always points to one culprit: a failing BCM. The internal circuits and relays wear out, causing erratic behavior. We installed one of our VIN-programmed BCMs, and within minutes of installation and a quick SDM key relearn, every single issue was resolved. The Yukon started right up, and all electronics functioned perfectly. It’s a common failure, but thankfully, it’s a straightforward fix with the right part.
Is Your Yukon Showing These Symptoms?
- ✔ The HVAC blower motor is dead or works only on certain speeds.
- ✔ Power windows, door locks, or interior lights are behaving erratically or not working at all.
- ✔ The anti-theft or security system prevents the vehicle from starting.
- ✔ An airbag warning light is on, often with a B1001 diagnostic trouble code.
- ✔ You’re experiencing strange electrical issues, like the radio staying on or gauges acting up.
- ✔ The windshield wipers operate randomly or won’t turn off.
Your 5-Minute Path to a Fully Functional Yukon
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the BCM: On most 2003-2006 Yukon 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 color-coded electrical connectors from the old BCM. Remove any mounting screws or clips holding it in place. Install the new module and securely reconnect all the connectors.
- Reconnect Power: Reattach the negative battery terminal.
- Final Relearn Procedures: While the module is plug-and-play for most functions, two critical steps are often required. Use a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the airbag light. Some vehicles may also require a brake pedal position sensor recalibration for optimal safety.

Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a common cause of this code. After installing the new module, the ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible scan tool to reset the light and ensure the system is communicating correctly.
Where is the BCM located on my GMC Yukon?
The Body Control Module is typically found under the driver’s side dashboard, mounted near the steering column for easy access.
What tools do I need for installation?
Basic hand tools, such as a socket or screwdriver for the mounting hardware, are all that’s needed for the physical swap. A professional scan tool is required for the post-installation airbag and brake sensor relearn procedures.
Is there a core charge for my old part?
No, there is no core charge. You can keep or dispose of your old module without the hassle of returning it.
