Are you battling frustrating electrical gremlins in your GM truck or van? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts on its own are often traced back to a failing Body Control Module (BCM).

Installation & Post-Install Notes
After installing the module, some vehicles may require additional simple procedures. If your airbag warning light is illuminated, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function to sync the systems. Additionally, a Brake Pedal Position sensor relearn might be necessary to ensure correct brake light and traction control operation. Always consult a factory service manual for vehicle-specific instructions.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before shipping it to you. It arrives ready to install, saving you time and the high cost of dealer programming.
How do I give you my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information.
Where is the BCM located on my vehicle?
For Silverado and Sierra pickups, the BCM is typically located under the steering column. For Savana and Express vans, it is usually found in the center of the dashboard.
What if the airbag light stays on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be synced with the airbag’s SDM module. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original, non-working module without needing to send it back to us.
Will this fix my specific electrical problem?
The BCM controls dozens of functions, and a failing one is a very common cause for the symptoms listed. While this part is the correct solution for a faulty BCM, you should always perform proper diagnostics to confirm the BCM is the source of your issue.
