Restore Your Van’s Core Electrical Functions
If your 2004-2007 GMC Savana 2500 is acting possessed—with flickering lights, a dead HVAC blower, or power locks with a mind of their own—the Body Control Module (BCM) is the likely culprit. As a technician with over two decades of experience, I’ve seen how a failing BCM can bring a reliable workhorse to a frustrating halt. This isn’t just an inconvenience; it’s a critical failure that can affect your work day and your vehicle’s security. This replacement Body Control Module, part number 10367690, is the definitive solution, arriving pre-programmed to your van’s specific VIN for a true plug-and-play repair.
The BCM is the central command for your Savana’s body electronics. It manages everything from the wipers and interior lights to the security system. When it fails, you get a cascade of seemingly unrelated problems. Our module restores these systems to factory-spec operation, eliminating the guesswork and the need for an expensive trip to the dealership for programming. This is the same reliable fix I’d perform in my own service bay to get a customer’s van back in service.
A Technician’s Notebook: The Intermittent Fleet Van
A local contractor brought in one of his 2006 Savana 2500 work vans with a list of bizarre complaints. The driver said the radio would cut out, the dome light would stay on, and sometimes the power door locks wouldn’t respond. He’d already replaced the battery and checked the main grounds. We scanned it and found a slew of communication DTCs, including a B1001. After verifying the network wiring, we pinpointed the BCM. These modules can fail internally, causing intermittent shorts and data corruption that create ghost-like symptoms. Installing a VIN-programmed 2004-2007 Savana 2500 BCM solved every single issue instantly. It’s a common failure point I’ve diagnosed on hundreds of these GM platforms.
Are You Experiencing These Common BCM Failure Signs?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ The HVAC system or blower motor works intermittently or not at all.
- ✔ An active airbag warning light, often with a DTC like B1001 (Option Configuration Error).
- ✔ The security system acts up, preventing the van from starting (Passlock issues).
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ Unexplained battery drain when the vehicle is off.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your van’s battery before starting any electrical work. This prevents shorts and helps reset the vehicle’s systems.
- ✔ Locate the BCM: In the Savana and Express vans, the Body Control Module is typically found in the center of the dashboard, often behind a lower access panel. You may need to remove a trim piece to get to it.
- ✔ Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Remove any mounting screws or clips holding it in place, then install the new module and reconnect the harnesses securely.
- ✔ Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all the functions controlled by the BCM: lights, locks, windows, wipers, and the climate control system to confirm the repair.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means we load your van’s specific Vehicle Identification Number (VIN) and all related factory software onto the module before we ship it. This ensures it communicates perfectly with your vehicle’s other computers (like the ECM and TCM) right out of the box, saving you from a mandatory and costly programming session at a dealership.
Is this a difficult part to install myself?
Not at all. For most DIYers with basic tools, this is a very manageable job that often takes less than 30 minutes. The primary challenge is accessing the module’s location in the dash. No special electronic tools are required for the basic installation.
Will I need to perform any procedures after installation?
In most cases, no. However, if your airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key’ procedure to sync the airbag system. Some models may also benefit from a Brake Pedal Position relearn, though this is less common. Always consult a service manual for your specific vehicle.
What if my original BCM has a different part number?
This module is a direct replacement for a wide range of part numbers, including 10367690, 15116066, 15136225, 15198116, and others. As long as your vehicle is on the compatibility list, this module will function correctly.
Is there a core charge?
No. We do not require you to send your old module back. There is no core charge, making the process simpler and faster for you.
