Restore Full Electrical Function to Your GM Truck or SUV
Are you experiencing a cascade of frustrating electrical problems in your GMC Yukon, Chevy Tahoe, or Silverado? Issues like flickering lights, unresponsive power windows, a malfunctioning HVAC system, or random warning lights are common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can make your truck or SUV feel unreliable. This genuine OEM-quality Body Control Module, part number 15943678 (interchangeable with 25844480 and others), is the definitive solution to restore your vehicle’s performance and peace of mind.

Before condemning your BCM, always perform a thorough check of the main ground connections, especially the one located under the driver’s side A-pillar trim. A loose or corroded ground is a common culprit for BCM-related symptoms on these GM platforms and can cause a new module to fail prematurely.
Is Your Vehicle Showing These Signs of BCM Failure?
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indication that your module needs replacement:
- ✔ Unresponsive or intermittently working power windows, door locks, or mirrors.
- ✔ HVAC system failures, such as a blower motor that won’t turn on or erratic temperature control.
- ✔ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, leading to no-start conditions, stalling, or misfires.
- ✔ Interior or exterior lights that stay on, won’t turn on, or behave erratically.
- ✔ A dashboard lit up with multiple, seemingly unrelated warning lights.
The Plug-and-Play Solution: A Pre-Programmed 2007-2011 Yukon BCM
Replacing a BCM used to mean a mandatory trip to the dealership for expensive programming. Our modules eliminate that step. We pre-program this 2007-2011 Yukon BCM to your vehicle’s specific Vehicle Identification Number (VIN) before shipping. This ensures that it integrates seamlessly with your existing systems right out of the box. The module arrives ready for a quick, straightforward installation, saving you time and money. Simply provide your VIN at checkout, and we’ll handle the rest, loading the latest GM software updates for optimal performance.
Post-Installation Procedures
While installation is simple, some vehicles may require a final sync procedure. If your airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary on certain models to ensure proper brake light and traction control operation. Always consult a factory service manual for vehicle-specific instructions.
