Restore Full Electrical Function to Your GM Truck or SUV
Is your GMC Yukon, Chevy Silverado, or Cadillac Escalade acting possessed? Flickering lights, unresponsive power windows, a dead HVAC system, or a persistent airbag light are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated electrical issues. This genuine quality GM 25844480 Body Control Module is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following issues, a faulty BCM is the most likely cause. Replacing it can resolve multiple problems at once, saving you time and diagnostic headaches.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights (headlights, dome lights, dash lights) staying on, flickering, or not working.
- ✔ HVAC and climate control functions are unresponsive, or the blower motor works sporadically.
- ✔ Vehicle security system malfunctions, causing alarm issues or no-start conditions.
- ✔ Airbag warning light is illuminated, often with a DTC B1001 code.
- ✔ Wipers behaving erratically or not responding to the switch.
- ✔ A variety of communication-related Diagnostic Trouble Codes (DTCs) stored in the system.
Why Our VIN-Programmed 2007-2011 Yukon BCM is the Superior Solution

This ensures that once installed, it communicates flawlessly with all other modules in your vehicle, just like the original part from the factory.

Installation and Post-Install Procedures
Installation is straightforward for the average DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. The physical swap takes less than 10 minutes. However, be aware of a few potential post-installation steps:
- Airbag System Sync: If the airbag warning light remains on after installation, a simple procedure called “Setup SDM Primary Key in BCM” is required. This must be done with a professional-grade scan tool and syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure proper brake light and stability control operation. This is also performed with a scan tool.

Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM acts as the central computer for your vehicle’s comfort and convenience features. It reads inputs from switches (like your window switch or headlight switch) and controls the corresponding outputs (like the window motor or headlights), managing everything from power locks and interior lighting to the security system and wipers.
Is this BCM really plug-and-play?
Yes, because we program it to your vehicle’s VIN before shipping. This critical step ensures it has the correct software and configuration for your specific model and options, allowing it to work immediately upon installation without needing a trip to the dealer for programming.
What if my airbag light is on after I install the new BCM?
This is a common security feature. You will need a professional scan tool to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag module (SDM) and will turn off the light. Most independent repair shops can perform this service quickly.
Do I need to send my old part back?
No. There is no core charge for this part. You can keep your old module, which simplifies the process and gets your vehicle back on the road faster.
Where is the BCM located on my 2009 GMC Yukon?
On the 2007-2011 GMC Yukon and similar GM platforms (Tahoe, Silverado, Sierra), the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column. It is a black box with several large electrical connectors.
