Restore Full Electrical Function to Your GM Vehicle
Are you battling perplexing electrical issues in your 2008-2012 GMC Savana 3500 or another compatible GM vehicle? A faulty Body Control Module (BCM) is often the culprit behind a host of frustrating problems. The BCM acts as the central nervous system for your vehicle’s body electronics, managing everything from your power windows and locks to the interior lights and security system. When it fails, it can cause unpredictable and seemingly unrelated symptoms, making diagnosis a challenge.
This replacement Body Control Module, part number 25826125, is the definitive solution. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific VIN before it ships. This ensures compatibility with your vehicle’s options and systems, simplifying the installation process significantly. Simply provide us with your VIN after purchase, and we’ll handle the programming with the latest GM software updates.
Is Your Savana 3500 Body Control Module Failing?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The vehicle’s security system malfunctioning or preventing the engine from starting.
- ✔ The radio or instrument cluster display behaving strangely.
- ✔ Dashboard warning lights (like the airbag or brake light) appearing for no reason.
- ✔ A “No Communication” error when a mechanic tries to scan the vehicle’s computer systems.
Installation and Post-Install Notes
While our VIN programming makes this a near plug-and-play part, some GM vehicles may require additional steps after installation to ensure all systems communicate correctly. These are known as ‘relearn’ procedures and may require a professional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct 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.
