Fix Annoying Electrical Problems in Your GM Truck or SUV
Are you dealing with strange electrical issues in your 2007-2011 GMC Sierra 3500, Chevrolet Silverado, or other GM vehicle? Flickering lights, a non-responsive HVAC system, or power windows with a mind of their own are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose problems. This genuine OEM-quality BCM, part number 15263497 (interchangeable with 25844480 and others), is the definitive solution to restore full functionality and reliability to your vehicle.

This ensures that it communicates perfectly with your truck’s other electronic systems right out of the box. There’s no need for a trip to the dealer or the use of a specialized scan tool for initial setup. This saves you time, money, and hassle, making the repair process as simple as possible.
Installation and Post-Install Notes
Installation is straightforward for most DIYers. The BCM is typically located under the driver’s side dashboard, near the steering column. In most cases, it’s a simple swap. However, please be aware of a few potential post-installation procedures:
- Airbag System Sync: If your airbag light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
This module is a direct replacement for a wide range of part numbers, including 15263497, 25844480, 25835966, 15878753, 20939137, and 22860591. Restore your vehicle’s performance and peace of mind with a reliable, ready-to-install BCM.
