Restore Your Vehicle’s Electronic Brain
Are you battling a cascade of frustrating electrical issues? Flickering interior lights, unresponsive power windows, a security system that has a mind of its own, or dashboard warnings that appear randomly?

The BCM is the central command hub for your vehicle’s body electronics, and when it falters, it can make your sophisticated car feel unreliable. This is the definitive solution to restore order, functionality, and your peace of mind.

Think of the BCM as the central nervous system for your car’s comfort and convenience features. It takes inputs from dozens of switches (like your window switch or headlight knob) and sensors, and sends commands to dozens of motors and lights. When it begins to fail, the signals get crossed, leading to the bizarre and unpredictable symptoms you’re seeing. Replacing it with a properly programmed GM Body Control Module 15880684 doesn’t just fix one problemโit restores the entire communication network, making your vehicle behave like it should.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide variety of non-engine-related electronic systems. This includes power windows, door locks, interior and exterior lighting, the security system, climate control fans, and more.
Is this module difficult to install?
The physical installation is typically straightforward, involving the removal of a few trim panels to access the module and unplugging/plugging in connectors. Because we pre-program the unit to your VIN, you avoid the most difficult part: the software setup. However, always consult a service manual for your specific vehicle’s procedure.
How does the VIN programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the correct software and vehicle-specific options from GM’s database. We then flash this information onto the GM Body Control Module 15880684 before shipping it to you.
What if my airbag light comes on after installation?
In some vehicles, the new BCM needs to be electronically introduced to the airbag system (SDM). If the airbag light is on after installation, a technician with a professional scan tool will need to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules.
Do I need to send my old part back?
No. This product comes with no core charge. You are free to keep or dispose of your original BCM, saving you the time, cost, and hassle of a core return.
Will this fix my specific electrical problem?
This BCM is the solution for a vast majority of the symptoms listed above. As the central hub for body electronics, its failure is a very common root cause. However, you should always perform proper diagnostics to rule out issues like bad wiring, fuses, or switches before replacing any computer module.
