Restore Full Electrical Control to Your GM Truck
Are you battling frustrating and unpredictable electrical problems in your 2006-2007 Sierra or Silverado? Flickering lights, malfunctioning power windows, a security system that acts on its own, or even a truck that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, and when it fails, it can cause a cascade of confusing issues. This replacement BCM, part number 15107479, is the definitive solution to restore your truck’s functionality and your peace of mind.
Unlike a generic part from a local store, this BCM is delivered to you fully programmed to your truck’s specific Vehicle Identification Number (VIN). This critical programming step ensures that the module communicates flawlessly with your vehicle’s other systems right out of the box, eliminating the need for an expensive trip to the dealership for software flashing. We handle the complex part so you can focus on the straightforward installation.
From the Diagnostic Bay
I once had a 2007 Silverado 2500 in the shop with a classic ‘gremlin’ case. The owner had replaced the battery twice and the alternator once, convinced it was a power supply issue. The dome lights would stay on, the radio would randomly shut off, and the power locks were completely unresponsive. After hooking up the scan tool, we saw a flood of communication errors all pointing back to the BCM. Instead of continuing to throw parts at it, we installed a VIN-programmed BCM. The moment it was connected, all the strange electrical issues vanished. It’s a powerful reminder that the BCM is the true brain behind the body, and diagnosing it correctly saves a lot of time and money.
Is Your BCM Failing? Common Symptoms
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or anti-theft light flashing, preventing the truck from starting.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Inaccurate gauge readings on the instrument cluster.
- ✔ Warning lights (like ABS or Airbag) illuminating for no apparent reason.
- ✔ A ‘no-start’ condition where the engine cranks but won’t fire up due to a security lockout.
The Plug-and-Programmed Solution for Your 2006-2007 Sierra BCM
This isn’t just a replacement part; it’s a complete, ready-to-install solution. By providing your VIN during checkout, you ensure that the 2006-2007 Sierra BCM arrives with the latest GM software updates already loaded, specifically configured for your truck’s options. This process is essential for proper function of features like keyless entry, automatic headlights, and other systems managed by the module. Installation is straightforward for a DIY mechanic or any professional technician.
Post-Installation Procedures
While our programming handles the majority of the setup, some vehicle systems may require a simple relearn or sync procedure after the new BCM is installed. These are standard industry procedures.
- Airbag System Sync: If your airbag warning light is on 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 bi-directional scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to satisfy the traction control system.

Frequently Asked Questions
Is this BCM plug-and-play?
Yes, it is. We program the module to your vehicle’s VIN before shipping, so it’s ready for installation without needing a trip to the dealer. However, as noted, some minor post-installation procedures like an airbag sync may be required depending on your vehicle.
Where is the BCM located on my 2006 Sierra or Silverado?
The Body Control Module is typically located under the driver’s side of the dashboard, near the steering column. It is a black plastic box with multiple large electrical connectors.
What happens if I forget to provide my VIN?
Providing your VIN is a required step for purchase. We cannot program or ship the module without it, as it will not function correctly in your vehicle. Our team will contact you if the VIN is missing from your order.
Will I need a special scan tool after installation?
In many cases, no special tools are needed. However, if your airbag light comes on, a professional-grade scan tool will be required to perform the ‘Setup SDM Primary Key’ procedure to sync the systems.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
