Restore Full Functionality to Your GM Vehicle
Are you experiencing bizarre electrical issues in your 2008-2012 GMC Savana 3500 Van? Problems like flickering interior lights, malfunctioning power windows and locks, erratic dashboard warnings, or a security system that acts up on its own are often caused by a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement BCM, part number 25892622, is the definitive solution to get your vehicle’s accessories working correctly again.
From the Diagnostic Bay
We had a contractor come in with his 2011 Savana work van. His dome lights would stay on, draining the battery overnight, and his power door locks worked intermittently. He was losing valuable time and money. After confirming the issue wasn’t a simple fuse or relay, we diagnosed a faulty BCM. Instead of a lengthy and expensive dealership visit, he ordered one of our pre-programmed modules. We installed it, and within an hour, all the strange electrical gremlins were gone. He was back on the road the same day, with his van’s systems operating as they should.
Diagnosing a Faulty Savana 3500 Body Control Module
A failing BCM can make you feel like your vehicle is possessed. Because it controls so many different functions, the symptoms can be widespread. If you’re noticing several of these issues at once, there’s a strong chance your BCM is the culprit.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, mirrors, or door locks.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ Erratic or non-working windshield wipers and washers.
- ✔ False warnings on the instrument cluster (e.g., ‘Service Airbag’, ‘Service Theft System’).
- ✔ The vehicle’s security system engaging randomly or preventing the engine from starting.
- ✔ Horn sounding unexpectedly or not working when pressed.
Plug-and-Play Solution Programmed to Your VIN
Don’t waste time and money at the dealership. We make this repair straightforward. When you purchase this Savana 3500 Body Control Module, you simply provide us with your vehicle’s VIN. Our experts will then program the module with the latest GM software specific to your van’s configuration. This ensures that when it arrives, it’s ready for installation without the need for an expensive programming tool. While the core functions will work immediately, please note that some vehicles may require minor post-installation procedures.
Post-Installation Information
Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This is a security measure. A professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and clear the light.
Brake Pedal Position Relearn: Certain models may also require a brake pedal position sensor relearn to ensure proper operation of the brake lights and traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module do on my Savana Van?
The BCM acts as the central hub for your van’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and instrument panel warnings.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving the removal of a few dash panels and disconnecting electrical connectors. Because we pre-program the module to your VIN, you avoid the most complex part of the job. However, some models may require simple relearn procedures as noted.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the exact factory software and configuration for your specific vehicle. Programming the BCM with this data ensures it communicates correctly with your van’s other modules, making the installation process as simple as possible.
What happens if my airbag light is on after installation?
If the airbag light is on, it means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my specific electrical problem?
This Savana 3500 Body Control Module is the correct fix for issues directly caused by a faulty BCM. While it resolves the vast majority of common electrical symptoms, we always recommend proper diagnostics to confirm the BCM is the root cause before ordering.
