Is Your Express Van Experiencing Bizarre Electrical Problems?
If your 2008-2012 Chevrolet Express 3500 is suffering from strange and unpredictable electrical issues, a failing Body Control Module (BCM) is the most common cause. The BCM acts as the central nervous system for your van’s body electronics, controlling everything from the power windows and locks to the interior lights and security system. When it starts to fail, it can create a host of frustrating problems that can bring your work or travel to a halt.
This is a direct-fit replacement Body Control Module, part number 25934763, that solves these issues. The best part? We program the module to your van’s specific Vehicle Identification Number (VIN) before we ship it. This means you get a part that’s ready for installation right out of the box, saving you from a costly trip to the dealership for programming.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The vehicle’s security system engaging randomly or not arming.
- ✔ The radio or climate controls behaving unpredictably.
- ✔ False warning lights on the instrument cluster, such as the airbag light.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.

Installation and Post-Install Procedures

- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn might be necessary.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We will program the Body Control Module to your vehicle’s VIN before shipping it to you. It will arrive ready to install.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find it on the driver’s side dashboard (visible through the windshield), on the driver’s door jamb sticker, or on your vehicle’s registration and insurance documents.
What happens if I forget to send my VIN?
We cannot ship your order without the VIN, as the programming is essential for the module to function in your vehicle. We will contact you to request the information, but this may delay your shipment.
Is this part truly ‘plug and play’?
For most vehicles, yes. The critical programming is done. However, as mentioned, some models may require additional relearn procedures for systems like the airbags or brake pedal sensor to fully sync with the new module.
