Restore Full Electronic Functionality to Your GM Vehicle
Is your Chevy Express Van or other GM vehicle plagued by bizarre electrical problems? Issues like flickering interior lights, malfunctioning power windows and locks, or an instrument cluster that seems to have a mind of its own often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating and unpredictable issues. This replacement Body Control Module, part number 25934763, is the direct-fit, reliable solution to get your vehicle’s systems operating correctly again.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ Erratic or non-functional instrument cluster gauges.
- ✔ Security system faults or the vehicle not recognizing the key fob.
- ✔ Unexplained battery drain (parasitic draw).
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Communication errors with other vehicle modules (DTCs).
Why Choose Our 2008-2012 Express 2500 BCM?
Getting your vehicle back to normal shouldn’t require a complicated and expensive trip to the dealership. Our process is designed to be simple and effective. This isn’t just a part in a box; it’s a complete solution. We take a high-quality BCM and program it specifically for your vehicle using your VIN. This means it arrives at your door with the latest GM software updates already installed, ready for installation. This critical programming step ensures that the module communicates perfectly with your vehicle’s existing components, like the engine computer, transmission module, and security system.
Installation and Post-Install Considerations
While the physical swap is often straightforward, please be aware of potential post-installation steps. Because this 2008-2012 Express 2500 BCM integrates with safety systems, some vehicles may require additional procedures. Specifically:
- Airbag System Sync: If your airbag warning light is illuminated 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 relearn may be necessary to ensure correct brake light and traction control operation.
We handle the primary programming, but these final security handshakes must be done on the vehicle. Always consult a factory service manual or a qualified technician if you are unsure.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s electronic accessories. It controls functions that are not related to the engine, such as power windows, locks, lights, wipers, the security system, and the instrument cluster.
Do I need to program this module?
No. We handle the programming for you before shipment. Simply provide us with your vehicle’s VIN after you place your order, and we will flash the module with the latest GM software specific to your vehicle.
How do I provide my VIN?
After completing your purchase, you can send us a message with your 17-digit VIN. We cannot ship your order until we receive this information to ensure correct programming.
What if my airbag light turns on after I install this?
This is a normal security measure on some vehicles. It means the new BCM needs to be electronically ‘introduced’ to the airbag module. A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a difficult part to install?
The physical replacement is typically simple, often located under the dash. However, due to the potential need for post-installation procedures like the airbag sync or brake pedal relearn, we recommend installation by a qualified mechanic with the proper diagnostic tools.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
