Restore Your Truck’s Electrical System with a VIN-Programmed BCM
Are you battling frustrating and unpredictable electrical issues in your 2006-2007 Sierra or Silverado HD? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are more than just annoyances—they’re often symptoms of a failing Body Control Module (BCM). The BCM acts as the central hub for your truck’s body electronics, and when it starts to fail, it can create a cascade of seemingly unrelated problems. Instead of chasing down individual component failures, the solution is often replacing this single, critical module.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take this genuine GM BCM, part number 15107479, and program it specifically to your truck’s Vehicle Identification Number (VIN) before it leaves our facility. This crucial step ensures that the module communicates flawlessly with your truck’s existing systems, like the engine controller and instrument cluster, saving you a costly trip to the dealership for programming.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights behaving erratically (flickering, staying on, or not turning on).
- ✔ The security system light is on, or the alarm goes off randomly.
- ✔ Horn honking unexpectedly or failing to work when pressed.
- ✔ Windshield wipers activating on their own or not responding to the switch.
- ✔ Issues with the radio, climate control, or other dash functions.
- ✔ False warning messages appearing on the driver information center.
The Direct-Fit Solution: Your Programmed 2006-2007 Sierra BCM
By choosing our pre-programmed 2006-2007 Sierra BCM, you are getting a module that is loaded with the latest software updates from GM. This not only restores original functionality but can also correct certain issues that were addressed in later factory software releases. The process is simple: place your order, provide us with your VIN, and we handle the complex programming. The part arrives at your door ready for physical installation.
Installation and Post-Install Considerations
The BCM is typically located under the driver’s side of the dashboard, near the steering column. Physical installation is a matter of disconnecting the negative battery terminal and then carefully swapping the electrical connectors from your old module to the new one. Once installed, most functions should be immediately restored. However, in some cases, additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary. This is also performed with a capable diagnostic tool.
We also make the process easier with our No Core Charge policy. You don’t have to worry about the cost or hassle of sending your old, faulty module back to us. Keep it, recycle it, or dispose of it as you see fit.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your truck that manages and controls electronic accessories not related to the engine, such as power windows, locks, lights, wipers, the security system, and climate controls.
Why do I need to provide my VIN?
Your truck’s VIN allows us to program the BCM with the specific software and settings for your vehicle’s options. This ensures it works correctly right out of the box and communicates properly with other modules, saving you a trip to the dealer.
Is this part difficult to install?
The physical installation is straightforward for someone with basic mechanical skills, as it’s typically located under the dash and involves swapping connectors. However, some vehicles may require post-installation procedures like an airbag sync or brake pedal relearn, which require a professional scan tool.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a high-end diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No. This product comes with no core charge. You can keep your original module without any additional fees or hassle.
Will this fix my specific electrical problem?
This module is the solution for a wide range of electrical issues listed in the symptoms. If your truck is experiencing multiple of those symptoms, a failing BCM is the most likely cause. Proper vehicle diagnostics are always recommended.
