Restore Full Functionality to Your 2004-2007 GMC Savana 2500 Van
Are you dealing with baffling electrical issues in your work van? A faulty Body Control Module (BCM) is often the culprit behind problems that can bring your business to a halt. This replacement BCM, part number 15136225, is the definitive solution for your 2004-2007 Savana 2500 BCM needs. It’s the central command for your van’s body electronics, and when it fails, it can cause a cascade of frustrating symptoms. Our professional cloning service transfers all the critical data from your original module to this replacement, ensuring a seamless, plug-and-play installation without any expensive dealership programming.
A Technician’s Notebook: The Contractor’s Van That Wouldn’t Start
A local contractor brought in his ’06 Savana 2500, a van essential to his livelihood. The complaint was intermittent no-starts and a radio that would turn on and off by itself. He’d already replaced the battery and checked the alternator. After connecting my scanner, I saw a handful of U-codes (communication errors) and a B1001 (Option Configuration Error). In my 20+ years of experience, this pattern almost always points to the BCM. These modules, especially in hard-working vans, suffer from thermal stress that causes microscopic cracks in the circuit board’s solder joints. We performed our cloning service on a replacement BCM, and the van fired up instantly. All the strange electrical gremlins were gone. It’s a classic fix that gets working professionals back on the job fast.
Is Your Savana Van Showing These Electrical Gremlins?
A failing BCM can manifest in numerous ways. If your van is experiencing any of the following, this module is your likely solution:
- ✔ The security or anti-theft light stays on, causing a no-start or crank-no-start condition.
- ✔ Power windows, door locks, or interior lights work intermittently or not at all.
- ✔ The HVAC blower motor is unresponsive, or the climate controls are dead.
- ✔ Your scan tool shows communication DTCs (U-codes) or specific BCM codes like B1001.
- ✔ The airbag warning light is illuminated on the dash.
- ✔ Wipers or exterior lights behave erratically, turning on or off without command.
A Straightforward Guide to Installation
Getting your Savana back in working order is simple. For most DIYers and professional mechanics, this is a quick job. This specific 2004-2007 Savana 2500 BCM is typically located in the center of the dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: Find the BCM, which is usually positioned in the center dash area, accessible from below.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module and remove it.
- Install the New BCM: Mount the replacement module and securely reconnect all electrical harnesses.
- Power Up: Reconnect the battery terminal. Start the vehicle to confirm that the primary issues are resolved.
- Post-Install Checks: In some cases, a ‘Setup SDM Primary Key in BCM’ procedure may be needed with a scan tool if the airbag light remains on. A Brake Pedal Position Relearn might also be required.

Frequently Asked Questions
What is a BCM cloning service?
Our cloning service is a precise process where we transfer the exact software, VIN, and security information from your original, faulty BCM to this replacement unit. This makes the new module a perfect digital copy of the old one, allowing it to work instantly in your vehicle without any additional programming.
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.
Will this finally fix my airbag light?
If the BCM is the source of the airbag fault, yes. However, after installation, if the light remains on, it means the BCM and the airbag’s Sensing and Diagnostic Module (SDM) need to be re-synced. This is a simple ‘Setup SDM Primary Key in BCM’ procedure that can be done with a professional-grade scan tool.
Is there a core charge for this part?
No, there is absolutely 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 core returns.
What tools do I need for installation?
Basic hand tools for accessing the dash panel and removing the module bolts are typically all that’s required. No special electronic tools are needed for the physical installation. A professional scan tool may only be necessary for optional post-installation procedures like the airbag sync.
