Restore Full Functionality to Your GM Vehicle with a Cloned BCM
Are you battling frustrating electrical gremlins in your work van or truck? Intermittent power windows, a dead instrument cluster, a security light that won’t turn off, or a blower motor with a mind of its own? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and security features, a faulty BCM can bring your daily operations to a halt. This replacement module, part number 15137393, is the definitive solution for your 2004-2007 Savana 3500 BCM and a wide range of other GM vehicles.
A Technician’s Notebook: The Case of the Unreliable Work Van
A few months back, a local contractor brought in his ’06 Savana 3500. The complaint was a laundry list of bizarre issues: the radio would cut out, the dome lights would flicker, and sometimes the power locks wouldn’t respond. He’d already replaced the battery and checked the main grounds. After hooking up my scanner, I saw a dozen communication codes pointing to the BCM. Instead of a costly and time-consuming dealership visit for a new, unprogrammed module, we opted for a cloning service. We transferred the data from his original, failing BCM to our replacement unit. The result? He was back on the road in under an hour with all electrical systems working perfectly. This is the power of a pre-configured, cloned module—it’s the fastest, most reliable fix.
What is a BCM Cloning Service?
Our expert cloning service makes this repair truly plug-and-play. We transfer the unique, vehicle-specific data—including VIN, mileage, and optional feature settings—from your original BCM directly onto this replacement unit. This process ensures seamless integration with your vehicle’s existing electronic systems without the need for expensive dealership programming or complex relearn procedures. You send us your old module, we clone it, and we send both the ready-to-install replacement and your original module back to you.
Is Your Savana Van Showing These Electrical Faults?
- âś” Intermittent or non-functional HVAC controls, including the blower motor or A/C.
- âś” An active airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- âś” Unresponsive power windows, door locks, or interior/exterior lighting.
- âś” Security system malfunctions, causing a no-start condition where the engine cranks but won’t fire.
- âś” Strange electrical behavior, like the radio turning off or gauges acting erratically.
- âś” A cluster of communication (U-codes) or body-related (B-codes) DTCs stored in the system.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- âś” Locate the Module: On the 2004-2007 Savana and Express vans, the BCM is typically found in the center of the dashboard, often accessible by removing a lower dash panel. For trucks and SUVs, it’s usually under the steering column.
- âś” Swap the Connectors: Carefully unplug the electrical connectors from your old BCM and plug them into your new, cloned module. The connectors are keyed to only fit one way.
- ✔ Reassemble and Test: Reinstall any panels you removed and reconnect the battery. Start the vehicle and test all body functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
Post-Installation Note: In some cases, particularly if the airbag light was on, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules. A Brake Pedal Position Relearn may also be required on certain models.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a BCM cloning service?
It’s a process where we copy the complete software and vehicle-specific configuration data from your original BCM to the replacement unit. This makes the new module an exact digital twin of the old one, ensuring 100% compatibility without any additional programming.
Will I need to take my van to a dealer after installation?
No. The cloning service eliminates the need for dealership programming. The module arrives ready for plug-and-play installation.
Do I have to send you my original BCM?
Yes, sending us your original module is required for the cloning service to work. We will return your original module along with the newly programmed replacement.
Where is the BCM located on my 2005 Savana 3500?
On the 2004-2007 Savana and Express vans, the BCM is located behind the center dash trim panel, usually below the radio and HVAC controls.
What if the airbag light stays on after I install the new BCM?
This indicates the BCM and the Sensing and Diagnostic Module (SDM) need to be electronically re-synced. A mechanic with a professional bidirectional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is there a core charge for this part?
No, there is no core charge. We require your original module for the service and return it to you with the replacement, so you keep both parts.
