If you’re dealing with bizarre electrical issues in your 2004-2007 GMC Savana 1500 Van, you’re not alone. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable workhorse into a source of constant frustration. One minute the wipers won’t turn off, the next the power locks have a mind of their own. This isn’t just an annoyance; for a work van, it’s a reliability and security problem. This is the central command for your vehicle’s body electronics, and when it fails, it can trigger a cascade of confusing symptoms.
We offer a straightforward, dependable solution: a high-quality replacement Body Control Module, part number 10367690, pre-programmed specifically to your van’s Vehicle Identification Number (VIN). This critical programming step means you can skip the expensive trip to the dealership and the hassle of their programming fees. It arrives at your door ready for a simple, plug-and-play installation, restoring full functionality to your van’s essential systems.
Is Your Savana Van Acting Up?
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, a failing BCM is the likely culprit:
- ✔ The HVAC blower motor works intermittently or not at all.
- ✔ Your power windows, door locks, or interior lights are behaving erratically.
- ✔ The security system is malfunctioning, preventing the van from starting.
- ✔ An airbag warning light is illuminated on the dash, possibly with a DTC like B1001.
- ✔ You’re chasing persistent grounding issues or communication error codes.
- ✔ The radio or instrument cluster randomly powers off and on.
A Technician’s Notebook: The Intermittent No-Start
I once had a 2006 Savana 2500 in my bay that drove the owner crazy. It would randomly refuse to start, but only on hot days after being driven. The battery was good, the starter was new, but the security light would flash. After hours of tracing wires, we found the issue was the BCM. Internal solder joints had cracked from years of heat cycles, causing an intermittent open in the security circuit. Replacing the BCM wasn’t enough; it had to be the right, properly programmed module. This is why our VIN-programmed 2004-2007 Savana 1500 BCM is the fix I trust for my customers—it solves the problem correctly the first time.
A Straightforward Guide to BCM Installation
For the GMC Savana and Chevrolet Express vans, the BCM is typically located behind the center dash panel. The process is simple enough for a DIY mechanic to complete in under 30 minutes.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
- Locate the Module: On your Savana van, the BCM is usually found in the center dash area. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module and remove it.
- Install the New BCM: Mount your new, VIN-programmed BCM in the same location and securely plug in all the electrical connectors.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, wipers, locks, windows, and HVAC to ensure everything is working correctly.
Post-Installation Note: In some cases, an airbag light may remain on. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync that pairs the new BCM with the airbag system.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that manages and controls a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, the security system, and HVAC fan speeds.
Why does this BCM need my van’s VIN?
We program the module to your specific VIN before shipping. This ensures it communicates perfectly with your van’s other computers and has the correct software for your vehicle’s options, enabling a true plug-and-play installation without a dealer visit.
Is this a difficult part to replace myself?
No, for most DIYers with basic tools, this is a very manageable job. The primary challenge is accessing the module’s location in the dash. The physical swap is just a few connectors and bolts.
What if my airbag light is on after installation?
This is not uncommon. It simply means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A mechanic with a bi-directional scan tool can perform the ‘Setup SDM Primary Key’ procedure in a few minutes to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module without any hassle or extra fees.
