Restore Full Electrical Function to Your GM Truck or SUV
Are you battling a cascade of frustrating electrical issues in your Cadillac Escalade, Chevy Silverado, or GMC Sierra? 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 acts as the central command center for your vehicle’s body electronics, and when it fails, it can make your vehicle feel unreliable and difficult to operate. This genuine GM Body Control Module, part number 25844480, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
We had a 2010 Silverado 2500 in the shop that was a real head-scratcher. The customer complained of the radio turning off randomly, the driver’s side power window only working intermittently, and the climate control blower motor cutting out. They had already replaced the blower motor resistor twice. We checked all the grounds and power feeds, which all tested fine. After connecting our scan tool, we noticed a flood of U-codes (communication errors) pointing back to the BCM. Instead of continuing to chase individual component failures, we identified the BCM as the root cause. A new, programmed module like this one resolved all the issues in under 15 minutes. It’s a reminder that when multiple, unrelated electrical systems act up, the BCM should be your primary suspect.
Symptoms of a Failing Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your BCM needs replacement:
- ✔ Unresponsive or erratic climate controls, including a blower that won’t turn on or works intermittently.
- ✔ Power windows, door locks, or mirrors that fail to operate correctly or at all.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Malfunctioning security system, leading to no-start conditions, stalling, or misfires.
- ✔ Exterior or interior lights (headlights, dome lights, dash lights) that won’t turn on, won’t turn off, or flicker.
- ✔ Wipers that behave erratically or don’t work when commanded.
Why Choose Our Programmed 2007-2011 Escalade BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. The biggest hurdle in BCM replacement is the need for expensive dealership programming. We eliminate that step entirely. By programming the module to your vehicle’s VIN before it ships, we ensure it integrates seamlessly with your existing systems. It will have the latest GM software updates and will be configured for the specific options your vehicle was built with. This saves you time, money, and the frustration of a trip to the dealer.
Post-Installation Procedures
While installation is straightforward, some vehicles may require a simple relearn procedure. If the airbag warning light remains on after installation, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ function with a professional scan tool. This syncs the new BCM with the airbag system. Additionally, a Brake Pedal Position Relearn may be needed to ensure proper brake light and traction control operation. These are standard procedures that any competent shop can perform quickly.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC system.
Is this BCM difficult to install?
Installation is typically very simple and takes less than 15 minutes for most DIYers. The BCM is usually located under the driver’s side dashboard, near the steering column, and is held in place by a few clips or bolts.
Do I need to take my vehicle to the dealer after installation?
No. This module comes pre-programmed to your vehicle’s VIN. This eliminates the need for any additional programming at a dealership, making it a true plug-and-play solution.
What happens if my airbag light is still on after installing this BCM?
If the airbag light persists, it simply means the new BCM needs to be electronically introduced to the airbag system. A technician can perform a ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to resolve this.
How do I know if this part fits my truck or SUV?
