Fix Your Van’s Electrical Headaches for Good
If your 2004-2007 GMC Savana 1500 Van is suffering from bizarre electrical problems, a failing Body Control Module (BCM) is the most likely culprit. As the central command for your van’s body electronics, a faulty BCM can cause chaos, from flickering lights to a no-start condition that leaves you stranded. This replacement BCM, part number 10367690, is the definitive solution. We utilize a professional Cloning Service, transferring the exact data from your original module to this new unit. This ensures a seamless, plug-and-play installation without the need for an expensive trip to the dealership for programming.
Is Your Savana Van Showing These Symptoms?
A failing BCM doesn’t always trigger a check engine light, often leaving owners and even some technicians chasing symptoms. Over my 20 years in diagnostics, I’ve seen these modules cause some of the most frustrating issues. Here’s what to look for:
- ✔ The security light is on, and the van won’t start or crank.
- ✔ Power windows, door locks, or interior lights work intermittently or not at all.
- ✔ The HVAC blower motor is erratic, or the climate controls are unresponsive.
- ✔ Your instrument cluster lights flicker, or gauges behave strangely.
- ✔ The airbag warning light is illuminated, often with a diagnostic trouble code like B1001 (Option Configuration Error).
- ✔ Communication errors with other modules are present when scanned.
A Technician’s Notebook: The Work Van That Wouldn’t Cooperate
I had a 2006 Savana 2500 work van come into the shop that was costing the owner a fortune in downtime. The complaint was intermittent: some days the power locks wouldn’t work, other days the radio would cut out, and occasionally the battery would be dead overnight. The owner had already replaced the battery and alternator. After checking for parasitic draws and finding nothing consistent, I hooked up the scanner. I found a slew of communication loss codes (U-codes) pointing to the BCM. A faulty BCM can create a ‘noisy’ data bus, waking up other modules and draining the battery. We cloned his original data to a new unit, and the van was back on the road the same afternoon, problem-free. This is a classic failure mode for the 2004-2007 Savana 1500 BCM.
A Straightforward Guide to BCM Installation
For the Savana and Express vans, this is one of the easier module replacements you can do. You can have your van back to normal in under 15 minutes.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: In your Savana van, the BCM is located in the center of the dashboard, typically accessible by removing a lower dash panel. It’s a black box with several large electrical connectors.
- Swap the Module: Carefully unplug the wiring harnesses from your old BCM. They have locking tabs, so be gentle. Remove any mounting screws or clips holding the old module in place and install the new, cloned module.
- Reconnect and Test: Plug the wiring harnesses firmly into the new module. Reconnect your battery terminal. Start the vehicle and test all functions: lights, locks, windows, wipers, and HVAC to confirm the repair.
Post-Installation Note: While our cloning service handles the primary programming, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on, or a ‘Brake Pedal Position Relearn’. These are simple procedures for any shop with a professional-grade scan tool.

Frequently Asked Questions
How does the cloning service work?
You send us your original Body Control Module. We then perform a full data transfer to the replacement unit, copying all your vehicle’s specific settings, key information, and mileage. This makes the new module a perfect electronic match for your van.
Do I need to get this programmed by a dealer?
No. Our cloning service completely eliminates the need for dealership programming, saving you time and hundreds of dollars in fees.
What is your core policy?
We do not require a core deposit, and your original module is always returned to you along with the newly programmed replacement. You can keep it or dispose of it as you see fit.
Is this a difficult part for a DIYer to install?
Not at all. For most owners with basic hand tools, this is a very straightforward job that takes less than 30 minutes. The BCM is typically easy to access under the dashboard.
What if my airbag light is on after installation?
In some cases, the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). This is called the ‘Setup SDM Primary Key in BCM’ procedure and can be performed by any qualified technician with a bi-directional scan tool.
