End the Electrical Headaches in Your GM Work Van
If you’re dealing with a 2004-2007 GMC Savana 3500 that seems to have a mind of its own—with flickering lights, a dead HVAC system, or power locks that work intermittently—the Body Control Module (BCM) is the most likely culprit. As the central command for your van’s body electronics, a failing BCM can cause a cascade of frustrating and costly problems. This replacement module, part number 15116066, is the definitive solution, offered with our expert cloning service to get your vehicle back in service with zero programming hassles.
Our unique cloning service makes this repair accessible to everyone. Simply send us your original BCM, and we will transfer all its critical data—including key information and vehicle-specific settings—to this replacement unit. The module you receive back will be a true plug-and-play part, eliminating the need for expensive dealership programming or specialized scan tools. This is the fastest, most reliable way to fix your 2004-2007 Savana 3500 BCM and restore full functionality.
A Technician’s Notebook
I had a local contractor bring in his ’06 Savana 3500. His complaint was a classic BCM failure story: the radio would cut out, the power door locks were dead, and worst of all, he’d get a random no-start condition that was making him late for jobs. He was losing money every day the van was unreliable. After confirming a faulty BCM with communication DTCs, we used our cloning service. He sent his old module in, we cloned it to a replacement 15116066, and sent it back. He installed it himself in the parking lot in under 10 minutes. That was six months ago, and his van has been running perfectly ever since. It’s a simple fix that makes a huge difference for a working vehicle.
Is Your Savana Van Showing These Electrical Faults?
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ HVAC blower motor or climate controls not responding correctly.
- ✔ The security system acting up, leading to frustrating no-start or crank-no-start situations.
- ✔ An active airbag warning light on the dash, often with a DTC like B1001 (Option Configuration Error).
- ✔ Unpredictable behavior from wipers, horn, or other electronic accessories.
- ✔ A cluster of communication or body-related Diagnostic Trouble Codes (DTCs).
Get Your Van Back to Work: Fast Installation Steps
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On Savana and Express vans, the BCM is typically found in the center of the dashboard, behind a lower access panel. It’s a black plastic box with several large electrical connectors.
- ✔ Swap the Module: Carefully unplug the wiring harnesses from your old BCM. Unbolt or unclip the module from its mounting bracket and remove it. Install the new, cloned module in its place and securely reconnect all wiring harnesses.
- ✔ Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions—lights, locks, windows, HVAC, and wipers—to confirm the repair was successful.
Post-Installation Notes
Thanks to our cloning service, post-installation procedures are rarely needed. However, in some cases, a vehicle’s specific configuration may require an additional step. If an airbag light appears, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ function. Similarly, a Brake Pedal Position relearn might be required on certain models. These are exceptions, not the rule, with our cloned modules.

Frequently Asked Questions
What is a BCM cloning service?
Our cloning service is a process where we transfer the exact software and vehicle-specific data from your original, faulty BCM to this replacement unit. This ensures 100% compatibility with your van’s features and security system, making the new module truly plug-and-play without any need for dealer programming.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, you must ship your original module to us after placing your order. We will perform the service and ship both your original module and the ready-to-install replacement back to you.
Is this repair difficult for a DIY mechanic?
Not at all. The physical swap is one of the easier repairs you can do. It involves removing a dash panel and unplugging a few connectors. With our cloning service, you skip the hardest part—the computer programming.
Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a very common cause of the B1001 code. Replacing it with our cloned module will resolve this issue by restoring the correct configuration data that the airbag system needs to see.
