Restore Your Vehicle’s Electrical Core and End Frustrating Gremlins
Are you battling bizarre and unpredictable electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or a no-start condition can all point to one central culprit: a failing Body Control Module (BCM). This isn’t just an annoyance; for a workhorse like a Chevrolet Express van, it’s downtime that costs you money. Stop chasing symptoms and replace the source of the problem with this professionally programmed BCM, designed to restore your vehicle’s full functionality and your peace of mind.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways, often making diagnosis difficult. If you’re experiencing any of the following, this module is the definitive solution:
- Erratic or non-working power windows, door locks, and mirrors
- Interior dome lights staying on or not working at all
- The security system randomly activating or preventing the engine from starting (check for security light on the dash)
- Inconsistent windshield wiper or HVAC blower motor operation
- Warning lights appearing on the dashboard without a clear cause
- Communication issues with other vehicle modules, leading to diagnostic trouble codes (DTCs)
This Programmed 25847588 Body Control Module arrives ready to install, pre-flashed with the latest official GM software specifically for your vehicle’s VIN. This critical step ensures all your vehicle’s original features and options work correctly right out of the box, saving you from an expensive and time-consuming trip to the dealership for programming.

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless vehicle owners buy a used BCM online, only to find it creates more problems than it solves. A BCM from a junkyard is programmed for a different vehicle—one with different options like a sunroof, different lighting, or a different security system. Installing it can cause features to stop working or new warning lights to appear. Our process of programming the module to your specific VIN before it leaves our facility is the only way to guarantee that the new BCM knows exactly how your vehicle was configured at the factory. It’s the difference between a quick, successful repair and a frustrating, costly ordeal.
Important Installation Notes
While this module is designed for a direct installation, some GM vehicles may require simple post-installation relearn procedures. These can typically be performed with a bi-directional scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a “Setup SDM Primary Key in BCM” procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be required on certain models to ensure proper brake light and traction control functionality.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that acts as a central hub for its body-related electronic features. It controls functions that aren’t related to the engine, such as power windows, locks, interior and exterior lighting, security system, wipers, and climate control fans.
How do I know if my BCM is failing?
Common signs of a failing BCM include multiple, unrelated electrical issues happening at once. This can range from flickering lights and malfunctioning power accessories to the security system preventing the car from starting. A professional diagnosis with a scan tool can confirm if the BCM is the source of the problem.
Is this part difficult to install?
The physical replacement of the BCM is typically straightforward for someone with basic mechanical skills, as it usually involves removing a few dash panels and unplugging connectors. Since our module comes pre-programmed, you avoid the most difficult step. However, some vehicles may require a simple relearn procedure with a scan tool after installation.
Why is providing my VIN so important?
Your Vehicle Identification Number (VIN) allows us to access the specific build data for your car from GM. We use this data to program the BCM with the correct software and settings for all of your vehicle’s factory-installed options. This ensures everything works perfectly upon installation, just as it did from the factory.
What happens if the airbag light comes on after installation?
This is a known possibility on some GM models. The new BCM needs to be electronically ‘introduced’ to the airbag control module (SDM). This is done via a simple “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool. A local repair shop can typically perform this for you.
Does this BCM fit vehicles other than the Express van?
Yes, absolutely. This specific BCM was used by General Motors across a very wide range of vehicles, including SUVs like the Tahoe and Acadia, sedans like the Impala and CTS, and other vans like the Savana. Please check the fitment list and your original part number to confirm compatibility.
