End the Electrical Gremlins in Your Work Van
If you rely on your 2004-2007 GMC Savana 2500 for work, you know that downtime is lost money. When your van’s electronics start acting upâflickering lights, a dead instrument cluster, or a security system that leaves you strandedâthe cause is often a failing Body Control Module (BCM). This isn’t just an annoyance; it’s a critical failure that can bring your operations to a halt. This replacement BCM, part number 15064149, is the definitive solution to restore your van’s electronic systems to factory-fresh condition, pre-programmed to your VIN for a true plug-and-play repair.
A Technician’s Notebook: The Case of the Unreliable Work Van
I had a contractor bring his ’06 Savana 2500 into my shop with a list of bizarre complaints. The dome lights would stay on, the power locks worked only half the time, and twice in one week, the van refused to start, flashing the security light. He’d already replaced the battery and checked the main grounds. After hooking up my scanner, I found a cluster of communication error codes and a B1001 DTC pointing to a configuration error. These symptoms are classic signs of an internally failing BCM. Instead of a costly trip to the dealer, we installed a VIN-programmed module. The swap took less time than the diagnostic scan, and all the electrical issues vanished instantly. The van was back on the road earning him money the same afternoon.
Is Your Savana Van Showing These Electrical Faults?
A failing BCM is the central point of failure for many electronic accessories. If you’re noticing these problems, it’s time to consider a replacement:
- â Unresponsive or erratic HVAC controls, including the blower motor cutting out.
- â The airbag warning light is illuminated, often with a related DTC like B1001.
- â Intermittent or total failure of power windows, door locks, or interior/exterior lighting.
- â The anti-theft or security system malfunctions, causing a no-start or crank-no-start condition.
- â A variety of communication codes or body-related DTCs stored in the system.

The biggest hurdle in replacing a BCM has always been the mandatory, expensive programming at a dealership. Our service eliminates that step completely. We flash this module with your van’s specific VIN and the latest GM software before it even ships. This ensures that all factory-set options for your 2004-2007 Savana 2500 BCM are correctly configured. The result is a simple, direct-fit replacement that restores function without extra costs or delays, making it the perfect choice for both professional mechanics and DIY-savvy fleet owners.
A Straightforward 5-Minute Installation Guide
- â Safety First: Disconnect the negative terminal from your van’s battery to prevent electrical shorts and allow the system to reset.
- â Locate the Module: On the Savana and Express vans, the BCM is typically found in the center of the dashboard, accessible from below. It’s a black box with several multi-pin connectors.
- â Swap the Connectors: Carefully release the locking tabs on each electrical connector and unplug them from the old BCM. Plug them into the corresponding ports on your new module until they click securely into place.
- â Mount the New BCM: Secure the new module back into its mounting bracket.
- â Reconnect and Test: Reconnect the negative battery terminal. Start the van and test all functionsâlights, locks, windows, wipers, and HVACâto confirm the repair was successful.

Frequently Asked Questions
What exactly does VIN programming do for me?
VIN programming configures the BCM with your van’s specific factory options, such as power windows, keyless entry, and security system settings. This ensures all features work correctly right out of the box, saving you from a mandatory and costly programming session at a dealership.
Is this part truly plug-and-play?
Yes. Because we program the module to your VIN before shipping, installation is as simple as unplugging the old unit and plugging in the new one. In most cases, no further steps are needed to restore full functionality.
Do I need to return my old BCM for a core charge?
No, there is absolutely no core charge. You can keep your old module, which makes the transaction simple and hassle-free.
My airbag light is on after installation. What do I do?
If the airbag light appears, it means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any qualified mechanic.
Where is the BCM located on my 2005 Savana Van?
On 2004-2007 Savana and Express vans, the Body Control Module is located in the center of the dashboard. You can typically access it by removing the lower dash trim panels. It’s a black plastic box with three or four large electrical connectors.
