Restore Full Electrical Function to Your GM Vehicle
Are you battling bizarre electrical issues in your 2008-2012 GMC Savana 2500? Flickering dashboard lights, malfunctioning power windows and locks, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and hard-to-diagnose problems. This replacement Body Control Module is the definitive solution to restore your vehicle’s stability and functionality.
From the Diagnostic Bay
We had a 2011 Savana work van come in that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and sometimes the power door locks wouldn’t respond. He’d replaced the battery and checked fuses, but the gremlins persisted. After hooking up our diagnostic tool, we saw communication errors pointing straight to the BCM. Once we installed a VIN-programmed replacement module like this one, all the strange issues vanished instantly. It’s a perfect example of how one faulty component can create a dozen confusing symptoms.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Dashboard warning lights (like ABS, Airbag, or Security) illuminating for no reason.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Vehicle’s anti-theft system preventing the engine from starting.
- ✔ Intermittent radio or climate control operation.
- ✔ False readings on the instrument cluster gauges.

Important Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require additional steps after installation to ensure all systems communicate correctly. These are not defects but standard procedures for modern vehicle electronics.
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN during or after checkout, and it will arrive ready for installation.

Is this a difficult part to install?
The physical installation is typically straightforward, requiring basic hand tools to access the module (often located under the dash). The key is the pre-programming we perform. However, as noted, some vehicles may require a final sync procedure with a professional scan tool.
What is a ‘core charge’?
There is no core charge for this part. You are not required to send your old, faulty module back to us.
Will this Savana 2500 Van Body Control Module fix my starting problems?
