Restore Full Functionality to Your Workhorse Van
If you’re dealing with perplexing electrical issues in your 2004-2007 GMC Savana 3500, the Body Control Module (BCM) is often the culprit. As the central command for your van’s body electronics, a failing BCM can cause a cascade of problems that take your vehicle off the road. This replacement BCM, part number 10367690, is the definitive solution. We offer a professional Cloning Service, where we transfer the precise data from your original module to this replacement. This ensures a seamless, plug-and-play installation without needing a trip to the dealership for expensive programming.
From the Diagnostic Bay: The Case of the Unreliable Work Van
I remember a 2006 Savana 3500 from a local contractor that came into my shop. The driver reported the weirdest problems: the dome lights would stay on, the power locks worked only half the time, and the A/C blower would quit randomly on hot days—a major issue for a work crew. They had already replaced the battery and checked grounds. After hooking up my scanner, I saw a handful of communication codes pointing to the BCM. Instead of a complex rewiring job, we swapped in a cloned BCM. The entire install took less than 15 minutes. All the strange electrical gremlins vanished instantly, and that van was back on the job site the same afternoon. This is a classic failure pattern for these hard-working vehicles.
Is Your Savana Showing These Symptoms?
A faulty BCM can manifest in numerous ways. Over my 20+ years in diagnostics, I’ve seen these modules cause some of the most frustrating issues for vehicle owners. If you’re experiencing any of the following, a failing 2004-2007 Savana 3500 BCM is the likely cause.
- ✔ Intermittent or non-functional power windows, door locks, or interior lighting.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ The security system acting up, leading to a no-start condition or the alarm going off unexpectedly.
- ✔ An airbag warning light on the dash, sometimes accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Erratic wiper operation or dashboard gauge malfunctions.
- ✔ Communication errors with other modules on the vehicle’s data network.
A Straightforward Guide to BCM Installation
Getting your Savana back in working order is easier than you think. For this model, the BCM is typically located in the center of the dash. The entire process should take only a few minutes.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents short circuits and helps reset the vehicle’s electronic systems.
- Locate the Module: Find the BCM in the center dash area. It will have several multi-pin electrical connectors attached to it.
- Remove the Old BCM: Carefully unplug the wire harness connectors. They have release tabs that you’ll need to press. Once disconnected, unbolt or unclip the module from its mounting bracket and remove it.
- Install the New BCM: Seat the replacement module into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a click when they are properly seated.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all the functions controlled by the BCM—lights, locks, windows, wipers, and HVAC—to confirm the repair was successful.
Post-Installation Procedures You Should Know
Our cloning service makes this a direct-fit part, but with complex vehicle systems, a couple of relearn procedures may be necessary. These are not always required but are good to be aware of.
- Airbag System Sync: If your airbag light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure brake lights and stability control function correctly.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
What is the ‘Cloning Service’?
Our Cloning Service involves transferring the exact configuration data from your original, failing BCM to the replacement unit. This process copies all your vehicle’s specific settings, ensuring 100% compatibility and avoiding the need for dealership programming. It makes the installation truly plug-and-play.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, you must send us your original module after placing your order. We will perform the service and ship both your original module and the ready-to-install replacement back to you promptly.
Is there a core charge?
No, there is no core charge. We always return your original module along with the programmed replacement, so you don’t have to worry about extra fees or returning a core.
What if my airbag light comes on after I install it?
This is uncommon but can happen. It means the BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). A procedure called “Setup SDM Primary Key in BCM” must be performed with a professional-grade scan tool to resolve this.
What tools do I need for installation?
Basic hand tools are all that’s required for the physical installation, typically just a socket or screwdriver to remove the mounting fasteners. No special programming tools are needed thanks to our cloning service.
