Get Your Truck Back on the Job, Fast.
Are you dealing with frustrating electrical issues in your GM truck or van? Flickering lights, power windows with a mind of their own, or a security light that prevents your vehicle from starting can bring your workday to a halt. These aren’t just annoyances; they’re problems that cost you time and money. This Body Control Module (BCM) is the definitive, hassle-free solution to restore your vehicle’s electronic systems to perfect working order. We take all the guesswork out of the repair by pre-programming the module to your vehicle’s specific VIN before it ships. This means no expensive trip to the dealership for programming—just a straightforward installation to get you back on the road.
Common Symptoms & Your Solution
A failing BCM can cause a wide range of confusing symptoms. If you’re experiencing any of the following, this module is the likely fix:
- Power windows, door locks, or interior lights operating erratically or not at all.
- The security or anti-theft light is on, causing a no-start condition.
- Dashboard warning lights appear randomly.
- Horn, wipers, or other accessories function intermittently.
- Communication issues with diagnostic scan tools.
Replacing the BCM with our professionally programmed unit resolves these communication breakdowns at their source, providing a reliable and lasting repair for your vehicle.

An Expert’s Note on GM Security Systems: Many GM vehicles from this era use a Passlock or Passkey anti-theft system that is directly tied to the BCM. A common failure point is this system malfunctioning, leaving you stranded. When you buy a used, non-programmed BCM, you’re often just buying a new headache because the security data won’t match your keys and ignition. Our process of programming this Programmed 2003-2007 Savana 3500 BCM to your VIN correctly syncs these critical security parameters, making the installation process as smooth as possible and preventing future no-start issues related to the anti-theft system.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that acts as a central hub for its body-related electronics. It controls non-engine functions like power windows, locks, interior and exterior lighting, wipers, the security system, and more. When it fails, these systems can become unreliable.
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 cannot ship your order until we receive this information, as it is essential for programming the module correctly for your specific vehicle.
Is any additional programming needed after installation?
Our pre-programming covers over 99% of the setup. However, in some cases, specific procedures like an ‘Airbag System Sync’ or a ‘Brake Pedal Position Relearn’ may be required using a professional scan tool if you see related warning lights after installation. This is vehicle-dependent and not always necessary.
Where is the BCM located on my truck or van?
For most Silverado and Sierra pickups, the BCM is located under the driver’s side dashboard, near the steering column. For Express and Savana vans, it is typically found behind the center dash area. Always consult a service manual for your specific model to confirm the location before beginning work.
Will this fix my specific electrical problem?
This BCM corrects issues directly caused by a faulty module. While it solves the most common electrical problems listed, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the source of your issue before purchasing. Our Programmed 2003-2007 Savana 3500 BCM is designed to be the final solution once the problem is identified.
