Are you experiencing frustrating electrical issues with your 2008-2012 GMC Savana 1500 Van? Flickering lights, malfunctioning power windows and locks, or strange warning messages on your dash are common signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of perplexing problems. This replacement Body Control Module, part number 20839063, is the definitive solution to restore full functionality to your vehicle’s accessories.
We make the repair process simple. Unlike going to a dealership, this BCM comes pre-programmed to your van’s specific Vehicle Identification Number (VIN). This means no expensive trips for programming; it arrives ready for installation. Simply provide us with your VIN after purchase, and we’ll flash the module with the latest GM software updates, ensuring optimal performance and compatibility with your vehicle’s specific options.
We had a contractor come in with his ’11 Savana work van. The dome lights would stay on, draining the battery overnight, and the power door locks worked intermittently. He’d already replaced the battery and checked every fuse he could find. A quick scan showed multiple communication errors pointing to the BCM. We installed a VIN-programmed module, and instantly, all the gremlins were gone. It saved him hours of lost work and the high cost of a dealership repair.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functioning interior and exterior lights.
- ✔ Power windows, mirrors, or door locks not working correctly.
- ✔ The security system engaging randomly or the vehicle not starting.
- ✔ False warning lights on the instrument cluster (e.g., Airbag, ABS).
- ✔ Radio or climate control malfunctions.
- ✔ Communication loss with other vehicle modules.

Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require minor post-installation procedures. If your airbag warning light is illuminated after installation, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a Brake Pedal Position relearn might be necessary on certain models to ensure proper brake light and traction control operation. Always consult a factory service manual for vehicle-specific instructions.
