Restore Your G8’s Electronic Brain
Is your 2008-2009 Pontiac G8 suffering from frustrating and unpredictable electrical issues? Flickering interior lights, malfunctioning power windows, a security system that acts up, or strange warning messages can all point to a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it fails, it can make your performance sedan feel unreliable. This is the definitive, hassle-free solution to restore your vehicle to perfect working order.

- Interior or exterior lights that stay on, flicker, or don’t work at all.
- Erratic instrument cluster behavior or false warning lights.

Frequently Asked Questions
What does a Body Control Module do on my Pontiac G8?
The BCM acts as the central hub for your car’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, the alarm system, and communicates with other modules throughout the vehicle to ensure everything works in harmony.
Do I need to send you my old BCM?
No. This BCM comes with no core charge. You can keep your original module, which saves you the time and expense of return shipping.
Is this a simple plug-and-play installation?
Because we pre-program the module to your VIN, it is as close to plug-and-play as possible. After the physical installation, some vehicles may require a simple relearn procedure for the brake pedal position sensor or the airbag system (SDM), which can be done with a compatible professional scan tool. We provide details on these potential post-installation steps.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please double-check your VIN for accuracy to ensure perfect programming.
What if my airbag light comes on after installation?
If the airbag light is illuminated after installing the new BCM, it means the module needs to be synced with the airbag’s Supplemental Deployment Module (SDM). This is done via a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool. This is a standard security procedure on many GM vehicles.
Will this specific programmed 2008-2009 Pontiac G8 BCM fit other cars?
Yes, while this listing is focused on the G8, the hardware (part number 25910474) is compatible with a very wide range of GM vehicles, including models from Chevrolet, Cadillac, GMC, Buick, and Saturn. The key is the VIN-specific programming we perform, which makes it correct for your exact vehicle.
