Is your 2006-2013 Chevrolet Impala experiencing bizarre electrical issues? Flickering lights, malfunctioning power windows, or a security system that prevents your car from starting are common signs of a failing Body Control Module (BCM). The BCM acts as the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating problems. This replacement BCM, part number 25910474, is the definitive solution to restore your vehicle’s functionality and peace of mind.
We make the repair process simple. This isn’t just a part in a box; it’s a complete, ready-to-install solution. Upon purchase, simply provide us with your vehicle’s VIN. Our technicians will then program the module with the latest GM software specific to your car. This ensures seamless integration and communication with your vehicle’s other systems, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2011 Impala come in that the owner described as ‘possessed.’ The horn would honk randomly, the interior lights would flicker like a strobe light, and the power locks had a mind of their own. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication loss codes with the BCM. Instead of a complex and costly diagnostic chase, we installed a VIN-programmed BCM. The strange behavior stopped immediately, and the car was back to normal. It’s a perfect example of how a single failing module can create widespread chaos.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Dashboard warning lights illuminating for no reason (e.g., security, ABS, airbag).
- ✔ The anti-theft or security system preventing the engine from starting.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ HVAC (heater and A/C) controls or blower motor behaving unpredictably.
- ✔ Remote keyless entry failure.
- ✔ Communication error codes stored in the vehicle’s computer system.

Post-Installation Requirements
While our programming handles the majority of the setup, some vehicles may require additional steps after installation. These are simple procedures for any qualified technician with a professional scan tool:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary for proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance. Getting a reliable 2006-2013 Impala BCM is the first step to a successful repair.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors many of the non-engine related electronic accessories, such as power windows, locks, lights, security system, and wipers.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings that your car had from the factory. This ensures all features work correctly and the module communicates properly with other computers in your vehicle.
Is this a difficult part to install?
The physical replacement is typically straightforward for someone with basic mechanical skills. On the Impala, it’s usually located in the driver’s side dash area. The most critical part is that our pre-programming service eliminates the need for dealer-level software tools, making the process much simpler.
Will this BCM fit other GM vehicles?
Yes, this BCM is compatible with a wide range of GM vehicles, including the Equinox, Acadia, various Express/Savana vans, and more. Our VIN programming ensures it will work correctly for any of the compatible models listed.
What happens if the airbag light comes on after I install it?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
