Restore Your Van’s Electrical System with a VIN-Programmed BCM
Are you battling frustrating electrical issues in your 2008-2012 GMC Savana 1500 or other compatible GM vehicle? Symptoms like flickering lights, malfunctioning power windows, a dead battery, or random warning messages on your dash often point to a single culprit: 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 create a cascade of confusing and disruptive problems. This replacement Body Control Module, part number 25826124, is the definitive solution to restore full functionality and reliability to your vehicle.
From the Diagnostic Bay
We had a customer with a 2011 Express work van who was ready to sell it for parts. The dome lights would stay on, draining the battery overnight, and the power locks worked only when they wanted to. He’d replaced the battery twice. After a quick diagnostic, we identified a faulty BCM. Instead of a costly trip to the dealer, we installed one of our VIN-programmed modules. The installation was straightforward, and instantly, all the electrical gremlins were gone. He was back on the road for his business the next day, saving hundreds in diagnostic fees and lost work time.
Why Choose Our Savana 1500 Body Control Module?
Getting your vehicle fixed shouldn’t be complicated. We simplify the process by programming this module to your vehicle’s specific VIN before we ship it. This means it arrives ready for installation, eliminating the need for expensive dealership programming or specialized scan tools for the initial setup. It’s a direct-fit, reliable solution designed to get you back on the road quickly and affordably.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ Instrument cluster warning lights (like the security light) illuminating incorrectly.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Intermittent starting problems or a complete no-start condition.
- ✔ Malfunctions with the A/C and climate control system.
- ✔ Rapid battery drain when the vehicle is off.
Installation and Post-Install Procedures
While the module is delivered programmed for your vehicle, some GM models may require additional system handshakes after installation. These are simple procedures for a qualified technician with a professional diagnostic tool.
- Airbag System Sync: If your airbag 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: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories like power windows, locks, lights, wipers, and the security system. It acts as the central hub for all non-engine related electronics.
Do I need to get this programmed at a dealership?
No. We handle the programming for you before shipment. Simply provide us with your vehicle’s VIN during checkout, and the module will arrive ready to be installed, saving you time and money.
Is this BCM difficult to install?
For someone with moderate mechanical experience, the physical installation is typically straightforward. It usually involves locating the module (often under the dash), disconnecting the battery, and swapping the electrical connectors. However, some vehicles may require post-install relearn procedures with a scan tool.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, faulty BCM back to us. This saves you the hassle and cost of return shipping and eliminates any core deposit fees.
What if my airbag light comes on after installation?
This is a known possibility on some GM vehicles. It simply means the new BCM needs to be electronically introduced to the airbag system (SDM). A technician with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
