Is Your GM Truck Experiencing Bizarre Electrical Problems?
If your 2007-2011 GMC Sierra, Chevrolet Silverado, or other GM truck or SUV is suffering from strange and frustrating electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central command center for your vehicle’s body electronics. When it malfunctions, it can cause a cascade of problems that are difficult to diagnose, from flickering lights to a non-starting engine. This VIN-programmed BCM is the definitive solution, designed to restore your vehicle’s full functionality right out of the box.

Expert Pro Tip
Before you install your new BCM, take a moment to inspect and clean the main ground connections, especially the one near the BCM’s location under the dash. A poor ground is a common cause of BCM failure and can cause recurring electrical gremlins even with a new part. Ensuring a solid ground connection is a simple step that can save you hours of future headaches.
Common Symptoms of a Failing BCM
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or flicker randomly.
- ✔ HVAC system failures, such as a blower motor that won’t work or blows at the wrong speed.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Vehicle security system malfunctions, causing no-start conditions or false alarms.
- ✔ Intermittent stalling, misfires, or other seemingly unrelated engine performance issues.
- ✔ A dashboard that lights up with multiple, unrelated warning lights.
Why Choose Our Programmed 2007-2011 Sierra 2500 BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra cost out of the repair by pre-programming the module to your vehicle’s specific VIN. This ensures that all factory settings and security information are correctly loaded, allowing for a seamless installation without requiring expensive programming tools or a trip to the dealership. This direct-fit 2007-2011 Sierra 2500 BCM is built to meet or exceed original equipment standards for performance and longevity.
Plug-and-Play Installation & Post-Install Notes
Physically replacing the BCM is straightforward. It is typically located under the driver’s side dashboard, near the steering column, and can be swapped in minutes. While our VIN programming handles the majority of the setup, some vehicles may require a simple relearn procedure after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” function using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to satisfy the traction control system.
This module is a direct replacement for a wide range of part numbers, including: 15263363, 15263497, 15878753, 15284816, 15943678, 15926094, 15940214, 25790508, 25790509, 25823558, 25823559, 25835965, 25835966, 25844479, 25844480, 25971916, 25971917, 15901388, 20939137, 20939138, and 22860591.
