Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your GMC Yukon, Chevy Silverado, or Cadillac Escalade? Flickering lights, unresponsive power windows, a malfunctioning security system, or erratic HVAC controls are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing issues. This genuine OEM-quality Body Control Module, part number 25844479 (interchangeable with 25844480), is the definitive solution to restore your vehicle’s performance and reliability.
Unlike standard replacement modules that require a costly trip to the dealership for programming, this BCM arrives at your door pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN). This means it’s a true plug-and-play solution, ready for immediate installation. We load the latest software updates from GM, ensuring optimal communication between all your vehicle’s systems and resolving common DTCs without any additional setup.
Expert Pro Tip
Expert Pro Tip
Before installing your new BCM, disconnect the battery. After installation, reconnect the battery and let the vehicle sit with the key in the ‘ON’ position (without starting the engine) for 10-15 minutes. This allows the vehicle’s various electronic systems to recognize and sync with the new module, which can prevent communication errors.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following issues, a faulty BCM is the likely culprit. Replacing it with our programmed 2007-2011 Yukon Body Control Module can resolve these problems:
- âš Power windows, door locks, or interior/exterior lights behaving erratically or not working at all.
- âš HVAC system failures, such as the blower motor not running or climate controls being unresponsive.
- âš The security system acting up, causing no-start conditions or random alarm activation.
- âš An illuminated airbag light, often accompanied by diagnostic trouble code (DTC) B1001.
- âš Unexplained battery drain while the vehicle is off, as the module fails to let other systems go to sleep.
- âš Wipers operating intermittently or not parking in the correct position.
Why Choose a VIN-Programmed Module?
The key to a successful BCM replacement is the programming. Your vehicle’s BCM is coded with specific information about its features, options, and security protocols. Our VIN programming service handles this critical step for you. By providing your VIN at checkout, you receive a module that is a perfect electronic match for your truck. This eliminates communication conflicts that can cause persistent issues and ensures all features, from power seats to remote start, function exactly as they did from the factory. This is the most reliable and efficient way to replace your 2007-2011 Yukon Body Control Module.
Critical Warning
Expert Pro Tip
Before installing your new BCM, disconnect the battery. After installation, reconnect the battery and let the vehicle sit with the key in the ‘ON’ position (without starting the engine) for 10-15 minutes. This allows the vehicle’s various electronic systems to recognize and sync with the new module, which can prevent communication errors.
Installation and Post-Install Procedures
Physically installing the BCM is straightforward. It is typically located under the driver’s side dashboard, near the steering column, and can be swapped in minutes. However, depending on your vehicle’s specific configuration, some post-installation steps may be necessary:
- Airbag System Sync: If the airbag warning light remains on after installation (often with code B1001), a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control functionality.
This module is a direct replacement for multiple part numbers, including 25844479, 25844480, 25835966, 15263363, 15878753, 15943678, 20939137, and 22860591. Restore your vehicle’s electronic systems with confidence by ordering this pre-programmed 2007-2011 Yukon Body Control Module today.
