Restore Full Functionality to Your GM Workhorse
Is your 2004-2007 GMC Savana 2500 Van suffering from baffling electrical problems? One minute the wipers work, the next they don’t? Are you dealing with a persistent airbag light or a no-start condition that’s costing you time and money? These are classic signs of a failing Body Control Module (BCM). This essential component is the central command for your van’s body electronics. When it fails, it can cause a cascade of frustrating and seemingly unrelated issues. This replacement BCM, part number 10367690, is the reliable, straightforward solution to get your vehicle’s systems communicating correctly again.
We offer a professional Cloning Service for this module. This means we transfer the critical data from your original BCM directly to this replacement unit. The result is a true plug-and-play component that requires no expensive trip to the dealership for programming. It will match your vehicle’s specific configuration, ensuring all features from power locks to HVAC controls work exactly as they did from the factory. This is the most efficient way to solve complex electrical issues caused by a faulty 2004-2007 Savana 2500 BCM.
Case Study: The Contractor’s Intermittent No-Start
A local electrician brought in his ’05 Savana 2500. The van would randomly refuse to start, the security light would flash, and the radio presets would disappear. He’d already replaced the battery and checked the ignition switch. After connecting my scanner, I saw a handful of U-codes (communication errors) pointing to the BCM. Instead of guessing, we pulled his original BCM, cloned the data to one of our quality-tested units, and sent him on his way. The new module restored stable communication between the security system and the ECU, solving the no-start for good. It’s a fix I’ve performed hundreds of times on these work vans.
Is Your Van Showing These Telltale BCM Failure Signs?
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft system acts erratically, causing a no-start or crank-no-start condition.
- ✔ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔ An airbag warning light is illuminated on the dash, often with a B1001 diagnostic trouble code.
- ✔ Wipers, turn signals, or other accessories behave unpredictably.
- ✔ A cluster of communication DTCs (U-codes) are stored in the vehicle’s memory.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning work. This prevents electrical shorts and helps reset system memory.
- ✔ Locate the BCM: On the Savana and Express vans, the BCM is typically found in the center of the dashboard, often behind a lower access panel. You may need to remove a few trim pieces to get to it.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Seat the replacement BCM into the mounting bracket and securely plug in all the electrical connectors you removed. You should hear a click as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: lights, locks, windows, wipers, and HVAC to confirm the repair.
Post-Installation Notes: In some cases, additional steps may be needed. If the airbag light remains on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a Brake Pedal Position relearn might be necessary on certain models. Always refer to a service manual for procedures specific to your vehicle.

Frequently Asked Questions
What is a BCM Cloning Service?
Cloning is a process where we transfer the exact VIN, mileage, and options data from your old BCM to the replacement unit. This makes the new module a perfect electronic match for your vehicle, eliminating the need for dealership programming and ensuring all features work correctly upon installation.
Do I need to send my original BCM to you?
Yes, for our cloning service, you will need to send us your original Body Control Module. We perform the data transfer in-house and then ship both your original module and the ready-to-install replacement back to you.
Is this a difficult part for a DIYer to replace?
Not at all. For most vehicles, including the Savana van, the BCM is accessible behind a dash panel and held in by a few bolts or clips. With basic hand tools, the physical swap can be done in under 15 minutes. Our cloning service handles the complicated software side for you.
Will this fix my airbag light?
If the airbag light is caused by a communication failure within the BCM (like a DTC B1001), then yes, this will resolve the root cause. However, after installation, you may need a technician with a high-end scan tool to perform a quick sync procedure to clear the light from the dash.
What is your warranty and core policy?
This BCM is backed by a one-year warranty. There is no core charge, and we always return your original module to you along with the newly programmed replacement. You get to keep your old part.
