Is your 2008-2012 GMC Savana or Chevy Express van suffering from bizarre electrical issues? The Body Control Module (BCM) is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating problems. This replacement Body Control Module, part number 25934762, is the definitive solution to restore full functionality to your vehicle. We take the guesswork out of the repair by programming the module to your van’s specific Vehicle Identification Number (VIN) before it ships. This ensures a seamless installation process and proper communication with your vehicle’s other systems.

Expert Pro Tip
Before replacing your BCM, always verify your battery’s health and check for clean, tight connections at the battery terminals and the main chassis ground. A weak battery or poor ground can mimic BCM failure symptoms, such as flickering lights or random warning messages. A simple check can save you time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ The radio or instrument cluster turning on and off randomly.
- ✔ False warning lights appearing on the dashboard.
- ✔ Inability for a diagnostic scan tool to communicate with the module.
Installing Your 2008-2012 Savana Body Control Module
This BCM is a direct-fit replacement for a wide range of original part numbers, including 15819552, 20815898, 22860591, and 25934762. Because we pre-program it with the latest GM software updates using your VIN, you can avoid a costly trip to the dealership for programming. After installation, some vehicles may require simple relearn procedures to sync all systems perfectly.
Post-Installation Requirements:
- Airbag System Sync: If the airbag warning light is illuminated after you install the new BCM, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary. This ensures your brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
