Is your GM truck or van experiencing bizarre electrical problems?
If your power windows, door locks, interior lights, or radio are acting erratically, or if you’re seeing a persistent security light on your dash, the culprit is often a failing Body Control Module (BCM). The BCM is the central computer responsible for managing your vehicle’s body electronics. When it fails, it can cause a wide range of frustrating and seemingly unrelated issues.
This is a direct replacement Body Control Module for a wide range of General Motors vehicles, including the Silverado, Sierra, Express, and Savana. We take the guesswork and high cost out of the repair process. Simply provide us with your vehicle’s VIN during checkout, and we will program the module with the latest GM software specific to your vehicle. This ensures a seamless installation process, getting you back on the road without a mandatory trip to the dealership for expensive programming.

Important Post-Installation Information
While this 2003-2007 GM BCM is designed for straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly.
- 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: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors many of the non-engine related electronic functions, such as power windows, locks, lights, security system, wipers, and more.
Is this BCM difficult to install?
Installation is typically straightforward. On most GM trucks, it’s located under the steering column, and on vans, it’s in the center dash area. It involves disconnecting the battery and swapping the module. However, please note the potential post-installation procedures mentioned above.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will use this to load the correct software for your specific vehicle before we ship the part to you.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after I install the new BCM?
This can happen on some vehicles. It means the new BCM needs to be electronically introduced to the airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a repair shop with a professional-grade diagnostic tool.
