Restore Full Control Over Your Vehicle’s Electronics
Is your Chevrolet Express or other GM vehicle suffering from bizarre electrical issues? Flickering lights, malfunctioning power windows, erratic door locks, or a security system that won’t cooperate are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating problems. This replacement Body Control Module, part number 25847588, is the definitive solution to restore your vehicle’s functionality and reliability.
We take the guesswork and hassle out of the replacement process. Unlike a standard part from a dealer or auto parts store, this module comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). Simply provide us with your VIN after purchase, and our technicians will flash the unit with the latest official GM software updates. This ensures seamless integration and communication with your vehicle’s other electronic systems, making installation as close to plug-and-play as possible.
From the Diagnostic Bay
We had a 2011 Savana 2500 work van come into the shop that was driving the owner crazy. The dome lights would stay on intermittently, the power locks worked only when they wanted to, and the radio would sometimes refuse to turn off after the key was removed. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication error codes pointing towards the BCM. Instead of a lengthy and expensive diagnostic chase, we recommended a VIN-programmed replacement. Once the new module was installed, every single electrical gremlin vanished. It was a night-and-day difference, saving the owner hours of lost work time and frustration.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t turn on at all.
- ✔ Malfunctioning windshield wipers or horn.
- ✔ Security system or keyless entry problems.
- ✔ Warning lights on the dashboard with no apparent cause.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Battery drain caused by components not shutting down correctly.

Important Installation Information
While this module is VIN-programmed for your vehicle, some models may require additional post-installation procedures. These are typically simple ‘relearn’ or ‘synchronization’ steps that can be performed with a capable bi-directional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be required.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions. By purchasing this 2008-2012 Express 1500 BCM, you are getting a reliable part that is ready to solve your vehicle’s complex electrical issues.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central hub for your vehicle’s body electronics. It reads inputs from switches (like power window or lock buttons) and sensors, and then sends commands to operate various accessories like lights, wipers, locks, security systems, and more. It’s essential for modern vehicle comfort and convenience features.
Do I need to get this module programmed?
No. We handle all the programming for you before the part is shipped. You just need to provide us with your vehicle’s 17-digit VIN during or after checkout. This ensures the module is configured for your specific options and features.
How do I provide my VIN?
After you complete your purchase, you can send us a message with your vehicle’s VIN. We cannot ship the module until we have this information to perform the programming service.
What if the airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve the light.
Is this a brand new part?
This is a quality, tested OEM replacement part. Each module is thoroughly inspected and verified to meet or exceed original factory specifications before being programmed with the latest GM software for your vehicle.
My original part number isn’t 25847588, will this still work?
Yes, this module is a direct replacement for a wide range of part numbers. Please check the detailed list of compatible part numbers in the description to confirm it matches one of the superseded or alternative numbers for your original BCM.
