Is Your GM Truck or Van Plagued by Electrical Gremlins?
Are you dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or a battery that drains for no apparent reason? These are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and unpredictable problems. Don’t let a faulty module keep your reliable GM vehicle off the road. This direct-fit BCM is the solution you need to restore full functionality and peace of mind.
Symptoms of a Failing GM BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system or horn activating randomly.
- ✔ Dashboard warning lights (like the airbag or brake light) illuminating incorrectly.
- ✔ Intermittent starting problems or a no-start condition.
- ✔ Unexplained battery drain that kills your battery overnight.
- ✔ Communication errors with other vehicle modules.
The Simple, Reliable Solution: A Programmed GM BCM Replacement
Forget about expensive dealership visits and complex programming procedures. We make the process simple. When you order this GM BCM Replacement, you provide us with your vehicle’s VIN. Our technicians will then program the module with the latest, most stable software directly from GM, ensuring it is perfectly matched to your vehicle’s specific options and configuration. It arrives at your door ready for installation, eliminating the need for special tools or costly subscriptions. This is the most efficient way to get your Silverado, Sierra, Express, or Savana back to 100%.
Installation and Post-Install Considerations
Installation is straightforward. The BCM is typically located under the steering column on trucks or in the center dash on vans. Simply disconnect the battery, remove the old module, plug in the new one, and reconnect the battery. While the module is programmed for your main vehicle functions, some safety systems may require a simple relearn procedure:
- Airbag System Sync: If your airbag warning light is on 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 may be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any step of the process.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories like power windows, locks, interior/exterior lighting, security systems, and wipers. It acts as a hub, communicating with various sensors and switches to operate these features.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your vehicle’s specific features and options. This ensures 100% compatibility and proper function right out of the box, just like a new part from the dealership.
Is this BCM difficult to install?
For someone with basic mechanical skills, the installation is generally simple. It involves disconnecting the battery and swapping the old module with this new one. However, some post-installation procedures, like an airbag system sync, may require a professional scan tool.
Will this fix my random battery drain?
A failing BCM is a very common cause of parasitic battery drain. The module can fail to ‘go to sleep’ after the vehicle is turned off, continuing to draw power and draining the battery. Replacing it often resolves this issue.
What happens if my airbag light comes on after installation?
If the airbag light appears, it means the new BCM needs to be electronically ‘introduced’ to the vehicle’s airbag system (SDM). This is a security measure and requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a repair shop with a professional-grade diagnostic tool.
