Tired of Unpredictable Electrical Problems in Your Savana Van?
If you’re a contractor or fleet owner, you know that a 2004-2007 GMC Savana 2500 Van is a workhorse. But when the Body Control Module (BCM) starts to fail, that reliable workhorse can turn into a source of constant frustration. Are you dealing with lights that flicker, door locks with a mind of their own, or a security system that prevents you from starting the engine? These aren’t just annoyances; they’re issues that cost you time and money. The BCM is the central command for your van’s body electronics, and when it goes, it can trigger a cascade of baffling problems.
This isn’t just another part. This is a complete, ready-to-install solution. We offer a professional Cloning Service with this module. Simply send us your original BCM, and we will transfer all of its vital data—including security information and vehicle-specific options—to this replacement unit. The result? You receive a module that is 100% plug-and-play. No expensive trips to the dealership, no need for advanced scan tools for programming. You can get your van back on the road and earning its keep in minutes.
From the Diagnostic Bay: The Case of the Contractor’s Van
A local electrician brought his ’06 Savana 2500 into my shop, completely fed up. Some days the dome lights wouldn’t turn off, draining the battery. Other days, the power door locks wouldn’t respond. He’d already replaced the battery and checked fuses, but the problems were random and getting worse. A quick scan revealed a handful of communication codes and a B1001 code related to the SDM. After 20 years of diagnostics, I’ve learned that when you see a collection of unrelated electrical gremlins on these GM platforms, the BCM is the prime suspect. Internal corrosion and failing solder joints are common culprits. We confirmed the BCM was failing. Instead of a costly new module and a day lost at the dealer for programming, he opted for our cloning service. We had his original data transferred to a replacement 2004-2007 Savana 2500 BCM, and he installed it himself in the parking lot. The van was back in service that same afternoon, problem solved.
Is Your Savana Van Showing These Electrical Gremlins?
- âś” The security light is on, and the van occasionally refuses to start.
- âś” Power windows, door locks, or mirrors work intermittently or not at all.
- âś” The HVAC blower motor is erratic, or the climate controls are unresponsive.
- âś” You have an airbag warning light on the dash, often with a DTC like B1001 (Setup SDM Primary Key in BCM).
- âś” Interior or exterior lights flicker, stay on, or fail to activate.
- âś” The instrument cluster displays strange warnings or loses communication.
Get Your Van Back on the Job: 5-Minute Installation Guide
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- âś” Locate the BCM: On the 2004-2007 Savana Van, the BCM is typically found in the center of the dash, often accessible by removing a lower dash panel.
- âś” Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have release tabs that need to be pressed. Once disconnected, remove any retaining bolts or clips holding the module in place.
- âś” Install the New Module: Seat your new, cloned BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- âś” Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, locks, windows, wipers, and HVAC to confirm the repair.
- âś” Post-Installation Check: In some cases, an airbag light may persist. This requires a professional scan tool to perform the “Setup SDM Primary Key in BCM” procedure. A brake pedal position relearn may also be needed on certain models.

Frequently Asked Questions
What exactly is a “Cloning Service”?
Cloning is a service where we transfer the complete software and vehicle-specific data (like VIN and security settings) from your original, faulty BCM to this replacement unit. This makes the new module a perfect electronic match for your van, eliminating the need for any additional programming.
Do I need a mechanic to install this?
No, installation is designed to be simple for a DIYer with basic tools. Because the module arrives pre-programmed via our cloning service, you just need to swap the old unit for the new one. The physical replacement typically takes less than 15 minutes.
Where is the BCM located on my 2005 Savana 2500?
On the Savana and Express vans from 2004-2007, the Body Control Module is located behind the dashboard, in the center area, usually accessible from below.
What if the airbag light is still on after I install it?
If the airbag light remains on, it means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed by a technician with a bi-directional scan tool.
Do I need to send my old part back for a core charge?
No, there is no core charge. We require your original module to perform the cloning service. Once the data is transferred, we securely package and return your original module along with your newly programmed replacement.
