Are you battling frustrating electrical issues in your GM vehicle? Intermittent power windows, malfunctioning door locks, erratic dashboard lights, or a security system that acts up are all classic signs of a failing Body Control Module (BCM).

Why Choose Our Programmed Savana 2500 Body Control Module?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. By providing us with your VIN during checkout, you ensure that the module you receive is a perfect match for your vehicle’s factory options. There is no core charge, so you can keep your old part. While the installation is straightforward for many, please be aware of potential post-installation procedures. Depending on your specific model, a ‘Brake Pedal Position Relearn’ or an ‘Airbag System Sync’ may be required if you see a related warning light after installation. These procedures typically require a professional-grade diagnostic tool. Always consult a service manual or a qualified technician for guidance.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and more.
Do I need to have this module programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you order, and the module will arrive ready to be installed with the latest software from GM.
How do I provide my VIN?
You can add your 17-digit VIN to the order notes during checkout. If you forget, we will contact you via email after your purchase to request it. We cannot ship the part until we have programmed it.
What if my airbag light is on after I install the BCM?
This can happen on some models. It means the new BCM needs to be synced with the airbag system’s computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional diagnostic tool to resolve this.
Is this part difficult to replace?
The BCM is typically located under the dashboard on the driver’s or passenger’s side. Replacement usually involves removing a few trim panels and disconnecting electrical connectors. It’s a manageable job for someone with basic automotive skills, but professional installation is always recommended if you are unsure.
Will this BCM fit vehicles other than the Savana 2500?
Yes, this BCM is compatible with a wide range of GM vehicles, including the Express Van, Tahoe, Suburban, Impala, Acadia, and more. Providing your VIN is the best way to guarantee you receive the correctly programmed part for your specific make and model.
