Restore Full Functionality to Your Vehicle’s Electronics
Is your GM vehicle exhibiting strange and frustrating electrical behavior? Issues like flickering lights, malfunctioning power windows and locks, a faulty security system, or even a no-start condition can often be traced back to a single component: the Body Control Module (BCM). The BCM acts as the central command center for your car’s body electronics, and when it fails, it can cause a cascade of problems. This replacement Body Control Module is the definitive solution to get your vehicle operating correctly again.
From the Diagnostic Bay
We had a 2008 Chevy Impala come in with the most bizarre symptoms. The owner said the radio would change stations on its own, the interior lights would pulse randomly, and sometimes the car just wouldn’t start. A scan showed multiple communication errors across different systems. Instead of chasing each individual ghost, we went straight to the BCM. After installing a VIN-programmed module like this one, every single issue vanished. It saved the customer hundreds in diagnostic fees and the headache of an unreliable car.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Intermittent issues with the radio or instrument cluster.
- ✔ Security system faults or the alarm going off unexpectedly.
- ✔ The vehicle failing to start, even with a good battery and starter.
- ✔ Warning lights on the dash, such as the airbag or brake light.

Don’t let a faulty BCM leave you stranded or dealing with an unpredictable vehicle. This module is a direct-fit replacement for a wide range of GM vehicles, including models from Chevrolet, GMC, Cadillac, Buick, Pontiac, and Saturn. The key benefit is our professional programming service. Simply provide your vehicle’s VIN during checkout, and we will flash the module with the latest GM software specific to your car. This ensures seamless integration and proper function of all your vehicle’s features, right out of the box.
This unit is a direct replacement for a wide array of part numbers, including: 10382479, 15828601, 15921352, 20815898, 22860591, 25892622, and many more. By ordering this module, you are getting a reliable part loaded with the correct software for your exact vehicle configuration.
Installation and Post-Install Considerations
Installation is typically straightforward, involving locating the old module (often under the dash or behind a kick panel), disconnecting the battery, swapping the modules, and reconnecting everything. However, due to the complexity of modern vehicle systems, some additional steps may be required after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and stability control systems function as intended.
We make the process easy by pre-programming the unit, which handles the most complex part of the job. Plus, there is no core charge, so you don’t have to worry about the cost or hassle of sending your old part back.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and instrument cluster functions.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive this information, as the programming is essential for the part to work in your car.
Is this a plug-and-play part?
Because we program it to your VIN, it is as close to plug-and-play as possible and eliminates the need for expensive dealer programming. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brake sensor after installation.
Will this fix my specific electrical problem?
This module is the solution for a wide range of common electrical failures. If your vehicle is showing multiple symptoms from the list above, there is a very high probability that a faulty BCM is the cause.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
Where is the BCM located on my vehicle?
The location varies by model. Common locations include under the driver’s or passenger’s side of the dashboard, behind a kick panel, or in the center console area. Your service manual will show the exact location.
