Are you dealing with baffling electrical issues in your Chevrolet Express or other GM vehicle? Symptoms like power windows that won’t budge, interior lights with a mind of their own, a security system that prevents you from starting, or random warning lights on your dash are classic signs of a failing Body Control Module (BCM).

From the Technician’s Bench:
As a tech with over 20 years of experience, I’ve seen countless vehicle owners waste time and money on used BCMs from salvage yards. A used module will never be a simple plug-and-play fix because it’s still programmed to the donor vehicle’s VIN and options. This creates communication errors and can even prevent the vehicle from starting. Our service of pre-programming this Programmed 2008-2012 Express 3500 BCM to your specific VIN eliminates that entire ordeal. You’re getting a part that’s electronically matched to your truck, just as a dealership would provide, but without the premium price tag.
Frequently Asked Questions
What exactly does a Body Control Module (BCM) do?
The BCM is the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and more. When it fails, these systems can become unreliable or stop working completely.
Why do you need my VIN number?
Your Vehicle Identification Number (VIN) is essential because it allows us to program the BCM with the specific software and settings for your vehicle’s exact make, model, year, and factory options. This ensures seamless integration and proper function after installation.
Is this BCM difficult to install?
For someone with basic mechanical skills, the physical replacement is typically straightforward. The BCM is usually located under the dashboard. Since we pre-program the module, you eliminate the most difficult step. However, always consult a service manual for your specific model’s location and procedure.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any professional shop with a compatible high-end scan tool. This is only necessary if the airbag light appears after the swap.
Does this part replace multiple part numbers?
Yes. This BCM, part number 25847588, is a direct replacement for over 30 different GM part numbers. We’ve included a comprehensive list in the product details to ensure you can confidently match it to your original unit.
What kind of assurance do I have with this part?
We stand behind our work. This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
