Restore Full Electrical Function to Your GM Van or SUV
If you’re battling bizarre electrical problems in your 2008-2012 Savana 3500 Van—like flickering lights, malfunctioning power windows, or a security system that has a mind of its own—a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating and seemingly unrelated issues. This isn’t just an inconvenience; it can impact your vehicle’s safety and reliability, especially for a workhorse like the Savana van.
We offer a dependable and straightforward solution. This Body Control Module is a direct-fit replacement, but with a crucial advantage: we program it specifically for your vehicle using your VIN before it ships. This means it arrives loaded with the latest GM software updates, ready for installation without requiring a trip to the dealership for expensive programming. Simply provide your VIN at checkout, and we handle the rest.
From the Diagnostic Bay: The Case of the Haunted Work Van
I once had a 2011 Savana 3500 work van come into my shop that was driving the owner crazy. The complaint was intermittent: the dome lights would stay on, the radio would randomly shut off, and the power locks would cycle while driving. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I found a slew of U-codes (communication errors) pointing to a network problem. In my 20+ years of experience, these symptoms almost always lead back to a failing BCM. The internal circuits degrade over time, causing data corruption on the CAN bus network. We installed a VIN-programmed BCM, and every single issue disappeared instantly. It’s a classic failure I’ve diagnosed on hundreds of these GM platforms.
Is Your Vehicle Showing These Common BCM Failure Signs?
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system or keyless entry functioning erratically or preventing the vehicle from starting.
- ✔ The horn sounding unexpectedly or not working when pressed.
- ✔ Warning lights on the dashboard, especially for the airbag or traction control system.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0100, U0140, or other U-series codes.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2008-2012 Savana and Express vans, the BCM is typically located in the center dash area, often accessible by removing lower dash panels. For other models, it may be under the steering column or behind the LH dash panel.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Perform Final Checks: Start the vehicle and test all body functions—lights, windows, locks, etc. Note that some vehicles may require additional relearn procedures as outlined below.
Important Post-Installation Information
While our VIN programming handles the majority of the setup, certain vehicle systems may require a ‘handshake’ with the new BCM. Depending on your specific model and options, you may need a professional scan tool to perform a Brake Pedal Position Relearn for proper traction control function or an Airbag System Sync (Setup SDM Primary Key) if the airbag light illuminates after installation. Always consult a factory service manual for your specific vehicle’s requirements.

Frequently Asked Questions
What does a Body Control Module actually do?
The BCM acts as the brain for your vehicle’s comfort and convenience features. It controls power windows, locks, lights, wipers, the security system, and more, by interpreting inputs from switches and sending commands to the appropriate components.
Why do I need to provide my VIN?
Providing your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your vehicle’s specific options. This ensures seamless integration and proper function, saving you a trip to the dealer for programming.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is generally a straightforward installation. The main challenge is accessing the module’s location within the dash. No special tools are typically required for the physical swap, but be aware that some models may require a post-install relearn procedure with a scan tool.
What happens if my airbag light is on after installation?
If the airbag light comes on, it means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a professional technician with a compatible diagnostic tool.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module, which saves you the time and hassle of dealing with a core return.
