Is your vehicle experiencing bizarre electrical problems?
If your power windows, door locks, interior lights, or radio are acting erratically, or if you’re facing intermittent starting issues, a failing Body Control Module (BCM) is often the culprit. The BCM is the central nervous system for your vehicle’s electronic accessories, and when it fails, it can cause a wide range of frustrating and unpredictable symptoms. Don’t let electrical gremlins take over your car. Restore full functionality and peace of mind with our pre-programmed replacement BCM.
From the Diagnostic Bay
We had a 2008 Chevy Equinox come in that was driving the owner crazy. The dash lights would flicker randomly, the radio would turn off, and sometimes the car just wouldn’t start. The battery and alternator tested fine. After hooking up the scan tool, we saw multiple communication errors pointing towards the BCM. Instead of a costly trip to the dealer for a new module and programming, the owner opted for one of our pre-programmed units. We installed it, the car started right up, and all the strange electrical issues were gone. It’s a common failure, and having a correctly programmed module is the key to a successful repair.

Post-Installation Information
While this GM Body Control Module is designed for a simple installation, some vehicles may require additional steps. If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. Additionally, some models may require a Brake Pedal Position sensor relearn to ensure proper brake light and traction control function. Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
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 functions, such as power windows, locks, lights, security system, and wipers.
Is this BCM really plug-and-play?
Yes, for most vehicles. We program it with the latest GM software using your VIN, so it communicates correctly with your car’s other modules. In some cases, minor relearn procedures, like for the airbag or brake pedal sensor, may be required after installation.
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 the module without it.
What if my airbag light is on after installation?
This indicates the BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A qualified technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this fix all of my car’s electrical problems?
This BCM will fix issues directly caused by a faulty module. However, it will not fix problems related to other components like bad wiring, faulty switches, or failing motors. Proper diagnosis is key.
