Is your Yukon, Tahoe, or Silverado plagued by frustrating electrical issues? A mind of its own—windows that won’t roll down, locks that act up, or an HVAC system that’s quit working—points directly to a failing Body Control Module (BCM). This vital component is the central nervous system for your vehicle’s comfort and security features. Restore complete and reliable functionality with this genuine GM 25844480 Body Control Module, pre-programmed specifically for your vehicle’s VIN for a true plug-and-play solution.

Expert Insight: The Importance of a Good Ground
From over 20 years of hands-on diagnostics, I can tell you that many BCMs are replaced unnecessarily due to a simple, overlooked issue: a bad ground. The primary BCM ground point on these GM trucks is located on the driver’s side A-pillar, near the emergency brake pedal. Over time, this connection can corrode or loosen, causing voltage drops that mimic BCM failure. Before installing your new 2007-2011 Yukon XL 1500 Body Control Module, take 5 extra minutes to locate, remove, and thoroughly clean this ground point with a wire brush. This simple step ensures your new module receives stable power and can prevent a host of future electrical gremlins, saving you time and money.
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s non-engine related electronics. It manages functions like your interior and exterior lights, power windows and locks, security system, wipers, and climate controls, ensuring everything works together seamlessly.
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific software and options—like whether you have power-folding mirrors or a rear entertainment system—onto the module. Without it, the BCM won’t know how to operate your vehicle’s features correctly. Our pre-programming saves you a mandatory and costly trip to the dealership.
My airbag light is on. Will this fix it?
Yes, this module often resolves the root cause of airbag codes like B1001. However, after installation, you may need to perform an ‘SDM Key Update’ or ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool to sync the new BCM with the airbag system and turn off the light.
How difficult is the installation?
The physical installation is straightforward for a DIYer with basic tools. The BCM is typically 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. The entire process usually takes less than 15 minutes.
My original part number isn’t 25844480, will this still work?
Yes, this part is a direct replacement for many different part numbers. Please check the interchange list on this page, which includes common numbers like 25835966, 15943678, and 22860591. As long as your vehicle model and year are listed, this programmed 2007-2011 Yukon XL 1500 Body Control Module will be the correct fit.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module without any penalty or need to ship it back to us.
