Restore Full Electrical Function to Your GM Truck or Van
Are you battling bizarre electrical gremlins in your Silverado, Sierra, Express, or Savana? Flickering lights, malfunctioning power windows and locks, or a security system that acts on its own are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues. This replacement BCM is the definitive solution to restore your vehicle’s functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ Communication errors with diagnostic scan tools (U-codes).
- ✔ A/C and climate control functions not working correctly.

Post-Installation Procedures
After installing your new 2003-2007 GM BCM, a couple of additional steps may be required to ensure all systems are synchronized:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary. This procedure calibrates the sensor to the new BCM, ensuring proper brake light operation and stability control performance.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
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 range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, security system, and climate controls.
Does this BCM need to be programmed by a dealer?
No. We handle all the programming for you. Simply provide us with your vehicle’s VIN during checkout, and we will program the module with the latest GM software specific to your truck or van. It will arrive ready to install.
Where is the BCM located on my vehicle?
On most compatible Sierra and Silverado pickups, the BCM is located under the steering column. On Savana and Express vans, it is typically found in the center of the dash.
What if my airbag light comes on after installation?
This is not uncommon. It means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is there a core charge for my old BCM?
No, there is no core charge for this part. You can keep your original module without needing to send it back.
