If your 2007-2011 Chevrolet Silverado 2500 is plagued by mysterious electrical problems, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central command for your truck’s body electronics. When it malfunctions, you can experience a frustrating array of issues, from flickering lights and non-responsive power windows to intermittent HVAC operation and even security system faults. This replacement BCM, part number 15263497, is the definitive solution to restore your vehicle’s full functionality.
We take the guesswork and dealership hassle out of the repair process. Each module is expertly programmed to your truck’s specific Vehicle Identification Number (VIN) before shipping. This ensures complete plug-and-play compatibility right out of the box. You won’t need to pay for expensive dealer programming or special tools—simply install the module and regain control over your truck’s essential systems.

Before replacing your BCM, always inspect the main ground connection under the driver’s A-pillar trim, often labeled G218 on wiring diagrams. A loose or corroded ground at this point is a very common issue on these GM trucks and can cause symptoms that perfectly mimic a failed BCM. Cleaning and tightening this ground can sometimes resolve the issue or prevent the new module from failing prematurely.
Common Symptoms of a Failing Silverado 2500 Body Control Module
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ The HVAC system or blower motor works intermittently or not at all.
- ✔ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ The security system malfunctions, causing no-start conditions or random alarm activation.
- ✔ Erratic behavior from dashboard gauges or windshield wipers.
- ✔ Multiple communication-related DTCs stored in the vehicle’s memory.
This module is a direct replacement for a wide range of GM part numbers, including 25844480, 25835966, 15263363, and more, ensuring a perfect fit for your Silverado, Sierra, Tahoe, Yukon, or other compatible GM vehicle. Installation is straightforward for those with basic mechanical skills and is typically located under the driver’s side dashboard. While the VIN programming handles the primary setup, be aware that in some cases, an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ may be necessary post-installation, which can be performed with a professional-grade scan tool.
