Tired of Unpredictable Electrical Problems in Your GM Van or Truck?
If you’re dealing with a 2004-2007 GMC Savana 1500 where the lights flicker, the power locks have a mind of their own, or the HVAC system won’t cooperate, the Body Control Module (BCM) is the likely culprit. As the central command for your vehicle’s body electronics, a failing BCM can cause a cascade of frustrating and seemingly unrelated issues. This isn’t just an annoyance; it can affect your vehicle’s security and your daily operations, especially for a workhorse like the Savana van.
This OEM-quality BCM, part number 15116066, is the definitive solution. But we go a step further. We offer a professional Cloning Service that makes this repair truly plug-and-play. 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 result? You receive a module that is 100% ready for installation, with no need for expensive dealership programming or complex relearn procedures. It’s the fastest, most reliable way to get your vehicle back to factory-spec performance.
From the Diagnostic Bay: The Case of the Intermittent Work Van
I had a local contractor bring in his ’06 Savana 2500. The van would randomly refuse to start, the security light would flash, and his dome lights wouldn’t turn off, draining the battery overnight. He was losing money every day it was down. After confirming power and grounds were good, we pinpointed a faulty BCM. Instead of sending him to a dealer, we used our cloning service. We transferred his original data to a replacement 15116066 module. He had it back the next day, plugged it in himself in under 10 minutes, and the van started right up—all problems solved. He avoided a tow, dealership labor costs, and most importantly, got his business moving again.
Your Guide to a Simple BCM Replacement
- ✔ Step 1: After placing your order, you’ll receive instructions on how to ship your original BCM to us.
- ✔ Step 2: Once we receive your module, we perform the cloning service, transferring all data to the replacement unit. We then ship both your original module and the ready-to-install replacement back to you.
- ✔ Step 3: Safety First: Before starting the installation, disconnect the negative terminal from your vehicle’s battery.
- ✔ Step 4: Locate the BCM: On Savana/Express vans, it’s typically found in the center dash area. On trucks and SUVs, it’s usually under the driver’s side dash near the steering column.
- ✔ Step 5: Swap the Modules: Carefully disconnect the electrical connectors from the old BCM and remove it. Connect the new, cloned BCM and secure it in place.
- ✔ Step 6: Final Steps: Reconnect the battery. Start the vehicle to confirm all functions (lights, locks, windows, etc.) are restored.
Is Your GM Vehicle Showing These Electrical Faults?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is the solution you need for your Savana 1500 Body Control Module and other compatible models:
- ✔ Unresponsive or erratic power windows, door locks, or interior/exterior lighting.
- ✔ HVAC system failures, such as a blower motor that won’t turn on or stays stuck on one speed.
- ✔ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Vehicle security system issues, including a flashing security light or a no-start condition where the engine cranks but won’t fire.
- ✔ Communication errors with other modules on the data network, leading to a host of other DTCs.
- ✔ Inconsistent wiper operation or other accessory malfunctions.

Frequently Asked Questions
What exactly is the cloning service?
Cloning is a process where we read the essential software and vehicle-specific data (like VIN, mileage, and key codes) from your original BCM and write it directly onto the replacement module. This makes the new part an exact electronic match to your old one, eliminating the need for dealer programming.
Do I get my original module back?
Yes, absolutely. Our policy is to always return your original module along with the fully programmed replacement unit. We do not keep cores.
Will this fix my airbag light?
In many cases, a faulty BCM is the cause of an airbag light with code B1001. Replacing it should resolve the issue. However, if the light remains on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool may be required to sync the systems.
Are any other procedures needed after installation?
Most of the time, no other steps are needed. On rare occasions, certain models may require a Brake Pedal Position (BPP) sensor relearn to ensure proper brake light and traction control function. This can be done with a capable bidirectional scan tool.
Is this a guaranteed fix for my 2005 Savana 1500 Body Control Module?
If your vehicle’s symptoms and diagnostic codes point to a failed BCM, and your part number is 15116066 or a compatible interchange, this service is the most reliable and straightforward repair available. It restores function by addressing the root electronic failure.
