Is Your Express Van Plagued by Bizarre Electrical Issues?
When your Chevrolet Express 2500 starts acting possessed—with flickering dash lights, unresponsive power windows and locks, a security system that won’t cooperate, or even a frustrating no-start condition—the root cause is often a failing Body Control Module (BCM).

Expert Insight: Avoid the Dealership Hassle
As a technician, I’ve seen countless van owners lose valuable time and money at the dealership for a BCM replacement.

Our solution consolidates this entire process.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as it is essential for programming the module correctly.
Is this a difficult part to install?
For someone with moderate mechanical experience, the installation is straightforward. The BCM is typically located under the dash. The main challenge is accessing it. Since our module is pre-programmed, the electronic part of the job is already done for you. However, we always recommend consulting a service manual for your specific vehicle.
Will I need to perform any other procedures after installation?
In some cases, yes. Depending on your vehicle’s specific configuration, a ‘Setup SDM Primary Key in BCM’ procedure may be needed if the airbag light comes on. Additionally, a Brake Pedal Position Relearn might be required. These are standard procedures that can be performed with a professional-grade scan tool.
What is a BCM and what does it do?
The Body Control Module (BCM) acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and more. When it fails, these systems become unreliable.
Does this module fit other vehicles besides the Express 2500?
Yes, this BCM is compatible with a wide range of GM vehicles, including the Savana, Tahoe, Suburban, Impala, Acadia, and more. Please check the detailed fitment list on this page to confirm compatibility with your specific make, model, and year.
