Restore Full Electrical Control to Your GM Vehicle
Is your 2008-2012 GMC Savana 2500 van plagued by strange and unpredictable electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often traced back to a single, critical component: the Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating issues. This replacement Body Control Module, part number 25910474, is the definitive solution to get your vehicle operating correctly again.

Before replacing your BCM, always perform a full battery and charging system test. Also, check the main power and ground connections to the BCM and at the chassis. A weak battery or a poor ground can mimic the symptoms of a failing module, and checking these simple things first can save you time and money.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. This module is designed to resolve these exact problems and restore your vehicle’s factory functions.
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The vehicle’s security system or keyless entry failing to work correctly.
- ✔ Dashboard warning lights (like the airbag or brake light) illuminating for no reason.
- ✔ Communication errors with other vehicle modules when scanned with a diagnostic tool.
- ✔ Rapid battery drain while the vehicle is parked.
