Restore Full Electrical Function to Your GM Vehicle
Are you battling bizarre and frustrating electrical problems in your 2008-2012 GMC Savana or other compatible GM vehicle? Issues like flickering interior lights, malfunctioning power windows and locks, erratic dashboard warnings, or a security system that acts up on its own are classic signs of 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 wide range of confusing symptoms. This replacement Body Control Module, part number 25826124, is the definitive solution to restore order and reliability to your vehicle’s systems.
From the Diagnostic Bay
We had a 2011 Express work van come in that was driving the owner crazy. The dome lights would stay on, draining the battery overnight. Then the power locks would stop working for a few hours, only to start working again. The driver’s side window was also intermittent. After checking all the usual suspects like fuses and wiring, we hooked up our diagnostic tool and found multiple communication loss codes with the BCM. A new, properly programmed module was the fix. It’s a perfect example of how a single failing computer can create a cascade of seemingly unrelated problems.
Diagnosing a Faulty Body Control Module
A failing BCM doesn’t always result in a simple check engine light. The symptoms are often more subtle and varied. If you’re experiencing any of the following, your BCM may be the culprit:
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The vehicle’s security system or keyless entry failing to work correctly.
- ✔ Warning lights (like ABS or Airbag) appearing on the dash for no reason.
- ✔ Gauges on the instrument cluster giving incorrect readings or not working.
- ✔ Communication errors when a diagnostic scanner is connected.
Why Choose Our Pre-Programmed 2008-2012 Savana BCM?
Getting back on the road shouldn’t be complicated. Dealerships often require you to have your vehicle towed in for BCM replacement and programming, leading to extra costs and downtime. We eliminate that hassle. We pre-program this module to your vehicle’s specific VIN before it ships. This means it arrives ready for installation, loaded with the latest GM software updates to ensure optimal performance and compatibility. This is the most efficient way to get your van or truck working correctly again.
Installation and Post-Install Steps
While physical installation is straightforward for a DIYer with basic tools, some electronic handshaking may be required after the new module is in place. Depending on your specific model and options, you may need a professional scan tool to perform procedures like an ‘Airbag System Sync’ if the airbag light comes on, or a ‘Brake Pedal Position Relearn’ to ensure brake light and stability control systems function correctly. We provide clear information on these potential steps to ensure you’re fully prepared.
