Restore Your Van’s Electrical System and Get Back on the Road
Is your Chevrolet Express 3500 van suffering from frustrating and unpredictable electrical problems? Flickering lights, unresponsive power windows and locks, or a dashboard that’s lit up with warnings can bring your workday to a grinding halt. These are classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics. Don’t let a faulty module compromise your van’s reliability. This is the direct, professional-grade solution to get your workhorse back in dependable service.
Common Failure Symptoms & Your Direct-Fit Solution
A failing BCM can cause a wide range of issues that can be difficult to diagnose. If your van is experiencing any of the following, a faulty BCM is the likely culprit:
- Power windows, door locks, or mirrors operating erratically or not at all
- Interior or exterior lights (headlights, taillights, dome lights) not functioning correctly
- Instrument cluster warning lights staying on, especially the security or airbag light
- Erratic or non-functional heating and A/C controls
- Remote keyless entry failing to work
- Vehicle security system preventing the engine from starting

An Expert’s Insight on BCM Programming
As a technician, I’ve seen countless hours and dollars wasted when a non-programmed BCM is installed. The BCM is like the vehicle’s central nervous system for all body electronics—it needs to know the exact options your van came with, from the type of radio to the power locks. Without VIN-specific programming, the module simply won’t work correctly, leading to even more frustrating issues. Our service handles this critical step for you, ensuring the module communicates perfectly with your van’s systems right out of the box. For a work vehicle like the Express 3500, this means a faster, more reliable repair that gets you back to earning money.
Important Post-Installation Notes
While this module is designed for a simple installation, some vehicles may require additional steps to sync all systems. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control functionality.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance. This 2008-2012 Express 3500 Body Control Module 25826125 is designed to be installed by a professional.

Frequently Asked Questions
Do I need to take my van to a dealer for programming after installation?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. This allows for a direct installation without the need for expensive dealer-specific tools.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN, or add it as a note to your order during checkout. We cannot ship the module until we receive the VIN.
What if the airbag light comes on after I install the BCM?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A qualified mechanic with a high-end diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a brand-new part?
This is a high-quality, fully tested electronic component that has been inspected to meet or exceed original performance standards. It is programmed with the latest software and is ready to provide reliable service.
My original part number is different. Will this still work?
Yes, this module replaces a long list of interchangeable GM part numbers. As long as your original part number is on the compatibility list provided in the description, this unit will function correctly in your vehicle once programmed to your VIN.
What tools are required for installation?
Basic hand tools are typically all that’s needed for the physical installation, such as a socket set and trim removal tools. However, as noted, a professional diagnostic scan tool may be required for post-installation procedures like the airbag system sync or brake pedal position relearn.
