Are you battling a storm of strange electrical problems in your GM truck or SUV? One moment the power windows refuse to work, the next the HVAC system has a mind of its own. These frustrating, seemingly unrelated issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can create chaos. This genuine GM Body Control Module, part number 25844480, is the definitive solution, pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
Common Symptoms of a Failing BCM
A faulty BCM can manifest in numerous ways. If your vehicle is experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Intermittent or non-functional power windows, door locks, or interior/exterior lights.
- ✔ HVAC system failures, such as the blower motor not working or temperature controls being unresponsive.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, leading to no-start conditions, stalling, or misfires.
- ✔ Unpredictable behavior from windshield wipers or other electronic accessories.
- ✔ A cluster of seemingly unrelated DTCs stored in the vehicle’s computer system.

Installation & Post-Install Notes
The BCM is typically located under the driver’s side dashboard, near the steering column. Physical installation is straightforward and usually takes only a few minutes. However, depending on your vehicle’s configuration, a couple of post-installation procedures may be necessary:
- Airbag System Sync: If the airbag light is on after installation, a technician will need to use a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ function. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
By choosing this pre-programmed 2007-2011 Escalade BCM, you are ensuring a precise and effective repair for your vehicle’s electrical system.
Frequently Asked Questions
What does a Body Control Module do on a Cadillac Escalade?
The BCM acts as the central computer for the vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, lights, wipers, the security system, and the HVAC system.
Is this BCM ready to install out of the box?
Yes! We program the module with your vehicle’s VIN before shipping, so it’s ready for a plug-and-play installation. No additional dealership programming is required for the module itself.
Why is my airbag light on after installing the new BCM?
The new BCM needs to be electronically ‘introduced’ to the vehicle’s airbag control module (SDM). This requires a ‘Setup SDM Primary Key’ procedure using a professional-grade scan tool to sync the components and turn off the light.
Where is the BCM located on a 2008 Chevy Silverado or similar GM truck?
On most 2007-2013 GM trucks and SUVs like the Silverado, Sierra, Tahoe, and Escalade, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
Do I need to return my old BCM?
No. This product comes with no core charge, so you can keep your original module without any extra fees or hassle.
Will this module fit my GMC Yukon or Chevy Suburban?
Yes, this BCM is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the Yukon, Suburban, Tahoe, Avalanche, Silverado, and Sierra. Please verify the part number for your specific vehicle.
