Is your GM truck or van experiencing bizarre electrical problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and door locks to the interior lights, security system, and instrument cluster warnings. When the BCM starts to fail, it can cause a cascade of confusing and frustrating issues that can be difficult to diagnose. A faulty BCM can leave you with a dead battery, malfunctioning accessories, or even prevent your vehicle from starting.
Common Symptoms of a Failing BCM:
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security system acting erratically or preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Instrument panel warning lights (like the airbag light) illuminating for no reason.
- ✔ Unexplained parasitic battery drain that kills your battery overnight.
- ✔ Wipers activating on their own or not responding to the switch.

Simply provide your VIN at checkout, and we’ll handle the complex programming for you.
Installation & Post-Install Notes
While this module is designed for a straightforward physical replacement, some vehicles may require additional steps after installation to ensure all systems are synchronized. Please be aware of the following potential procedures:
- 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: Some models may require a brake pedal position sensor relearn to ensure correct operation of the brake lights and traction control system.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors the body-related electronic accessories in your vehicle. This includes power windows, locks, lights, wipers, the security system, and more.
Is this part ready to install out of the box?
Yes, this BCM comes pre-programmed to your vehicle’s VIN. This handles the most critical step, making installation much simpler. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake systems after installation.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship the module until we receive this information, as the programming is specific to your vehicle.
What if the airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
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 BCM fit my vehicle?
This module fits a wide range of 2003-2007 GM trucks and vans, including Silverado, Sierra, Express, and Savana models. Please review the detailed fitment list on this page to confirm compatibility with your specific year, model, and options.
