Tired of Electrical Gremlins in Your GMC Yukon?
If your 2007-2011 GMC Yukon is starting to act possessed—with flickering lights, a dead instrument cluster, or power windows with a mind of their own—the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it goes bad, it can cause a cascade of frustrating and seemingly unrelated electrical issues. This replacement BCM, part number 15263497, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
A Technician’s Notebook: The Misleading Ground Fault
I remember a 2008 Yukon XL that came into my bay with the weirdest collection of symptoms: the radio would cut out on right turns, the driver’s side window wouldn’t work, and the security light was always on. The owner had already spent a weekend chasing ground wires under the dash, convinced it was a simple connection issue. After hooking up my scanner, I saw a dozen communication codes pointing everywhere. From experience, I know that on these GMT900 platforms, a failing BCM can mimic a bad ground perfectly. We swapped in a pre-programmed BCM, and every single issue vanished instantly. It’s a 10-minute fix that can save you hours of diagnostic headaches.
Is Your Yukon Showing These Telltale Signs?
- ✔️ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔️ The security system acts up, causing a no-start condition or random alarms.
- ✔️ An airbag warning light on the dash, often with a DTC like B1001.
- ✔️ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔️ Strange instrument cluster behavior or warning lights that come and go.
- ✔️ A host of communication-related Diagnostic Trouble Codes (DTCs).
Your 5-Minute BCM Installation Guide
Replacing the 2007-2011 Yukon BCM is a straightforward job for any DIYer. Located under the driver’s side dashboard, it’s designed for easy access.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronics.
- Locate the Module: Find the BCM mounted to a bracket beneath the steering column. It will have several large electrical connectors plugged into it.
- Swap the Modules: Carefully depress the locking tabs on each electrical connector and pull them straight out. Unclip or unbolt the old BCM from its bracket and set it aside.
- Install the New BCM: Secure your new, pre-programmed BCM onto the mounting bracket. Firmly plug in all the electrical connectors until they click into place.
- Power Up: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
Post-Installation Note: In some cases, an airbag light may remain on. This requires a professional scan tool to perform the “Setup SDM Primary Key in BCM” function. This is a simple sync procedure, not a full reprogramming. Also, a Brake Pedal Position relearn may be needed on certain models to ensure proper brake light function.

Frequently Asked Questions
Do I need to have this BCM programmed by the dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. It arrives ready for a plug-and-play installation, saving you a trip to the dealership.
Is this a new or used part?
This is a high-quality, OEM-grade replacement part that has been expertly tested and programmed to meet or exceed original factory specifications. It comes with a one-year warranty.
What if my airbag light is on after installation?
If the airbag light persists, it means the BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This is done with a bi-directional scan tool using the ‘Setup SDM Primary Key’ function. It’s a quick procedure for any professional mechanic.
Why is my 2007-2011 Yukon BCM failing?
Failures can be caused by a number of factors, including voltage spikes from a bad alternator or battery, water intrusion from a leaky windshield, or simple internal component fatigue over time.
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 any hassle or extra fees.
