Finally, A Real Fix for Your GM’s Electrical Gremlins
Are you dealing with a frustrating array of electrical issues in your truck or SUV? One minute the air conditioning works, the next it doesn’t. The power windows have a mind of their own, and a persistent airbag light stays on your dash. These aren’t separate problems—they’re classic signs of a failing Body Control Module (BCM). This genuine GM BCM, part number 25844480, is the central command for your vehicle’s body electronics. We pre-program it to your vehicle’s specific VIN, ensuring it arrives ready for a simple, plug-and-play installation that restores the full, reliable functionality you depend on.

Expert Insight: Don’t Chase Ghosts in the Machine
As a technician, I’ve seen countless hours and dollars wasted trying to diagnose BCM failures. A customer might replace a window motor, a light switch, and a blower resistor, only to find the problems persist. That’s because the BCM is the ‘brain’ telling those components what to do. When it fails, it sends corrupt signals, making good parts act bad. Replacing the BCM first often solves a dozen problems at once, saving you from a frustrating and expensive diagnostic journey.
Frequently Asked Questions
What does the Body Control Module do on my truck?
The BCM is a computer that manages and controls most of your vehicle’s non-engine-related electronic functions. This includes the power windows, door locks, interior and exterior lighting, security system, wipers, and the HVAC (heating and air conditioning) system.
Why is VIN programming so important for a BCM?
VIN programming loads your vehicle’s specific software and security information onto the module. Without it, the BCM won’t be able to communicate with the other computers in your vehicle, like the Engine Control Module (ECM) or Airbag Module (SDM). This can lead to features not working or even a no-start condition. Our pre-programming service eliminates this problem.
Is this 2007-2011 Yukon XL 1500 Body Control Module difficult to install?
No, the physical installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard, near the steering column. It’s held in by a few clips or bolts and has several electrical connectors. Most people with basic tools can swap it out in under 15 minutes.
My airbag light is on. Will this fix it?
Yes, this module will often resolve airbag light issues caused by a BCM communication fault (like DTC B1001). However, in some cases, a post-installation procedure called an ‘SDM Key Update’ or ‘Airbag System Sync’ must be performed with a professional scan tool to finalize the communication link between the new BCM and the airbag system.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your old module, which saves you the time and hassle of packaging and shipping it back.
What other vehicles is this part compatible with?
This BCM fits a wide range of 2007-2013 GM trucks and SUVs, including the Chevrolet Silverado, Suburban, Tahoe, Avalanche; GMC Sierra, Yukon; and Cadillac Escalade. It directly interchanges with numerous part numbers like 15943678, 25835966, 20939137, and 22860591, among others.
