Restore Peak Electrical Performance to Your Pontiac G8
Is your 2008-2009 Pontiac G8 plagued by frustrating electrical gremlins? Issues like erratic power windows, flickering lights, a malfunctioning security system, or strange instrument cluster behavior often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of seemingly unrelated problems. This replacement Body Control Module, part number 95151084, is the definitive solution to restore your vehicle’s functionality and reliability.
The Simple, VIN-Programmed Solution
Forget expensive trips to the dealership and the hassle of programming a new module. We handle the complex part for you. When you purchase this BCM, you simply provide us with your vehicle’s VIN. Our technicians will then program the module with the latest official GM software specific to your G8’s exact configuration. This ensures that all factory options and security protocols are correctly matched, making the installation process as smooth as possible. Your new 2008-2009 G8 BCM will arrive at your door ready to be installed.
From the Diagnostic Bay
We had a 2009 G8 GT come into the shop with a list of bizarre symptoms. The owner reported that the radio would cut out intermittently, the driver’s side power window would only work sometimes, and the key fob would randomly fail to lock the doors. Initial checks of fuses and wiring showed nothing obvious. A deep dive with a diagnostic scanner revealed multiple communication errors all pointing back to the BCM. Instead of a stable signal, the module was sending corrupted data packets across the CAN bus network, causing chaos with other modules. Installing a VIN-programmed BCM like this one resolved every single issue in one go, transforming the car from an electrical nightmare back into the reliable performance sedan it was meant to be.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ The anti-theft or security system acting up, preventing the car from starting.
- ✔ Key fobs that stop working or have intermittent functionality.
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’ light when all doors are closed).
- ✔ Malfunctions with the radio, climate control, or other interior accessories.
- ✔ Parasitic battery drain that leaves you with a dead battery overnight.
Installation and Post-Install Procedures
This BCM is located in the center dash area of your Pontiac G8. While the physical replacement is straightforward for a skilled DIYer or any professional technician, some vehicles may require additional electronic relearn procedures after the new module is installed. This is a normal part of the process as the new BCM syncs with your car’s other systems.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This ensures the BCM and the airbag system are communicating correctly.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be necessary to ensure proper operation of the brake lights and stability control systems.
Please consult a factory service manual or a qualified technician for detailed instructions specific to your vehicle.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to load the exact software and configuration that your car had when it left the factory. This ensures all your specific options (like sunroof, specific lighting, security system) work correctly without any additional programming required on your end.
Is this BCM difficult to install?
The physical installation is manageable for someone with moderate mechanical skill, as it involves accessing the module in the dash and swapping connectors. However, some vehicles may require post-installation electronic ‘relearn’ procedures using a professional scan tool, as mentioned above.
Do I need to return my old BCM?
No. This product comes with no core charge. You can keep your original module, which can be helpful for double-checking part numbers or for any future reference.
Will this fix my car’s specific electrical problem?
This module will resolve any issues directly caused by a faulty BCM. If you are experiencing any of the symptoms listed above, the BCM is a very likely cause. However, we always recommend a proper diagnosis by a qualified technician to rule out other potential issues like bad wiring, grounds, or fuses.
What is the difference between this and a used BCM from a junkyard?
A used BCM from another vehicle is programmed to that vehicle’s VIN and options. It will not work correctly in your car and will likely cause more problems, including immobilizer issues that prevent the car from starting. Our BCMs are supplied with fresh software programmed specifically for your car, ensuring compatibility.
