Restore Your Van’s Electrical System and Get Back to Work
If your 2004-2007 Savana 3500 Van is plagued by baffling electrical problems—like the climate control having a mind of its own, power locks refusing to work, or the security system preventing a start—you’ve likely found the culprit: a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and security features, a faulty BCM can bring your operations to a halt. This replacement BCM, part number 10383536, is the definitive solution. Through our expert cloning service, we transfer the unique data from your original module to this new unit, making installation a true plug-and-play process without any need for expensive dealership programming.
A Technician’s Notebook: The Case of the Commercial Van
A local contractor brought in his ’06 Savana 3500 work van with a list of complaints that sounded like a random electrical storm. The dome lights would flicker, the radio would cut out, and worst of all, the van would occasionally refuse to start, flashing the security light. He’d already replaced the battery and checked grounds. After hooking up my scanner, I saw a handful of communication codes, including the infamous B1001. In my 20+ years of experience, these ghost-like symptoms on GM vehicles almost always point to an internal BCM failure. We ordered a module with a cloning service. Once it arrived, we simply swapped it in. The van started right up, and every single electrical gremlin was gone. For a business owner, getting their vehicle back on the road that fast without a trip to the dealer is a huge win.
Is Your Savana Van Exhibiting These Telltale Signs of BCM Failure?
A failing BCM doesn’t always cause a complete breakdown. Often, it starts with small, annoying issues that grow worse over time. Here are the most common symptoms I see in the shop:
- ✔ Intermittent or non-functional HVAC and blower motor controls.
- ✔ Strange power window and door lock behavior.
- ✔ An active airbag light on the dash, often accompanied by DTC B1001 (Option Configuration Error).
- ✔ Security system malfunctions that lead to a no-start or no-crank condition.
- ✔ Unpredictable operation of interior or exterior lights.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs).
A Straightforward Guide to Installation
One of the best parts of our cloning service is that it makes the physical replacement incredibly simple. You can have your Savana’s electrical systems restored in minutes.
- Safety First: Always disconnect the negative terminal on your vehicle’s battery before working on electrical components.
- Locate the Module: In the 2004-2007 Savana Van, the BCM is conveniently located in the center of the dash area, making it easy to access.
- Swap the Connectors: Carefully unclip the wiring harnesses from your old BCM and plug them securely into your new, programmed module. The connectors are keyed to only fit one way.
- Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all the functions that were previously malfunctioning—lights, locks, windows, and HVAC—to confirm the repair.
- Post-Installation Checks: In some cases, a post-install procedure like an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ may be needed if you see related warning lights. This requires a professional scan tool.

Frequently Asked Questions
What exactly is a BCM cloning service?
Our cloning service is a simple process where we transfer the specific software and vehicle data from your original, failing BCM directly onto the replacement unit. This ensures the new module is a perfect digital match for your van, preserving all original settings and security information without needing a trip to the dealer.
Will I need to do any programming after I install it?
No. Because we clone your original module’s data, this BCM arrives ready for plug-and-play installation. You will not need a scan tool for initial programming, which saves you significant time and money.
Where is the BCM located on my 2005 Savana 3500?
For the 2004-2007 Savana and Express vans, the Body Control Module is typically found behind the center dash panel. Access is generally straightforward after removing a few trim pieces.
What if the airbag light stays on after installation?
If the airbag warning light is illuminated after you install the new BCM, it means the module needs to be synced with the airbag system’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. It’s a quick process for any qualified technician.
Do I need to send my keys with my old module?
No, you do not need to send us your keys. The cloning process only requires your original Body Control Module to transfer the necessary data.
What is your core policy?
We make it simple: there is no core charge. After we complete the cloning service, we ship your original module back to you along with the newly programmed replacement. You get to keep your old part.
