Restore Full Electrical Function to Your GM Truck or SUV
If your Silverado, Sierra, or Tahoe is plagued by mysterious electrical issues like flickering lights, unresponsive power windows, or a dead HVAC system, a failing Body Control Module (BCM) is the most likely cause. The BCM is the central command center for your vehicle’s body electronics. When it fails, it can create a cascade of frustrating problems. This genuine OEM-quality Body Control Module, interchangeable with part number 25835966, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play installation.
Is Your 2007-2011 Silverado BCM Failing?
A faulty BCM can manifest in numerous ways, often mimicking other component failures. Before you start replacing switches and motors, check if you’re experiencing any of these classic symptoms of BCM failure. This module is the correct fix for these common issues.
Common Failure Symptoms
- ✔ Power windows, door locks, or mirrors not working or operating erratically.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on or not turning on at all.
- ✔ HVAC and climate control functions are inoperative or behaving unpredictably.
- ✔ Vehicle security system malfunctions, causing alarm or starting issues.
- ✔ Wipers won’t turn on, off, or operate at the correct speed.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Various diagnostic trouble codes (DTCs) related to body systems stored in the vehicle’s memory.
The Plug-and-Play Advantage: VIN Programming Included
Don’t waste time and money at the dealership. We program this module to your vehicle’s specific VIN before it ships. This crucial step ensures that the BCM communicates perfectly with your truck’s other electronic systems right out of the box. It eliminates the need for expensive scan tools or additional programming fees, making the repair process faster, simpler, and more affordable. Simply install the module, and you’re ready to go.
Post-Installation Notes
While installation is a direct swap, some vehicles may require a simple relearn procedure. If your airbag warning light remains on after installation, a technician will need to perform the “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 might be necessary on certain models to ensure proper brake light and traction control operation.
