Are you battling frustrating electrical gremlins in your GM truck or van? Issues like flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement GM Body Control Module is the definitive solution to restore your vehicle’s electronic functions and get you back on the road with confidence.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair process by pre-programming the module to your vehicle’s specific VIN before it ships. Simply provide your VIN at checkout, and our technicians will flash the BCM with the latest, most stable software updates from GM. This ensures perfect integration with your vehicle’s existing systems and saves you a costly trip to the dealership for programming.

- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.

Important Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems function correctly. Please be aware of the following potential procedures:
- 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. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation or post-installation 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 controls and monitors a wide variety of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Is this BCM truly plug-and-play?
Yes, for most vehicles. Because we program it to your VIN before shipping, it arrives ready to be installed without the need for dealer programming. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake systems.
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 ship your order until we receive your VIN to program the module.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the vehicle’s airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. This product has no core charge, so you can keep your original module without any additional fees.
Will this fit my Crew Cab truck?
Please check the fitment data carefully. This specific BCM fits many models but typically excludes Crew Cab configurations for the Silverado and Sierra pickups.
