Is Your GM Vehicle Experiencing Bizarre Electrical Problems?
If your car’s lights are flickering, windows won’t operate, the security system is acting up, or you’re facing an intermittent no-start condition, a failing Body Control Module (BCM) is often the culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues. Don’t let electrical gremlins keep you off the road. This direct-replacement BCM is the reliable solution to restore full functionality to your vehicle.
From the Diagnostic Bay
We had a 2011 Chevy Impala come in that was driving the owner crazy. The dash lights would flicker randomly, the radio would cut out, and sometimes the car just wouldn’t start. The battery was new and the alternator tested fine. After checking the main power and ground circuits, we hooked up our professional scan tool and found multiple communication loss codes with the BCM. Instead of a costly trip to the dealer for a new module and programming fees, the owner ordered one of our VIN-programmed units. It arrived ready to install, and once swapped, all the strange electrical issues were gone. It’s a common story for a failing GM Body Control Module.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Security system light is on, or the alarm goes off randomly.
- ✔ Vehicle won’t start, or the starter doesn’t engage (clicking noise).
- ✔ Instrument cluster gauges behaving erratically or not working at all.
- ✔ Key fob is unresponsive.
- ✔ Warning lights (like ABS or Airbag) appearing on the dash.
Why Choose Our Programmed GM Body Control Module?
This isn’t just a part; it’s a complete solution. We take the hassle out of the repair by programming the module to your vehicle’s specific VIN before we ship it. This means the unit arrives loaded with the latest GM software updates for your exact make and model, ensuring optimal performance and compatibility. This critical step saves you from needing expensive specialty tools or a trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest. Plus, with no core charge, you can keep your old part without any extra hassle.
Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require minor post-installation procedures. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer that manages many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, and wipers.
How do I know if my BCM is the problem?
Common signs include multiple, unrelated electrical issues happening at once. A professional diagnosis with a scan tool that can communicate with the BCM is the best way to confirm a failure.
Is this part truly plug-and-play?
Because we program it to your VIN, it is as close to plug-and-play as possible. It eliminates the need for dealer programming. However, as noted, some vehicles may require minor additional relearn procedures for systems like the airbags or brake sensor.
Where do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we receive this information.
What if my original part number isn’t 10382479?
That’s okay! This module is a direct replacement for the long list of part numbers shown in the description. As long as your original part number is on our list, this module will work for your vehicle.
