Restore Full Functionality to Your GM Truck or SUV
Are you tired of chasing down bizarre electrical problems in your Silverado, Sierra, or Tahoe? One moment your power windows work, the next they don’t. The HVAC controls have a mind of their own, and a persistent airbag light is driving you crazy. As a technician with over 20 years of experience, I can tell you these aren’t random glitches; they’re classic signs of a failing Body Control Module (BCM). This VIN-programmed BCM, part number 15064149, is the definitive, hassle-free solution to restore your vehicle’s electronic systems to factory-perfect operation.
A Technician’s Notebook: The Silverado with a Ghost
A 2005 Silverado 2500 HD came into my shop with a laundry list of complaints: the radio would cut out, the driver’s side door lock wouldn’t respond, and the ‘Service Airbag’ message was on. The owner had already replaced the battery and checked fuses. My initial scan pulled a B1001 DTC, pointing to a configuration error, along with several U-codes for lost communication. Instead of hours spent chasing wires, my experience pointed straight to the BCM. These modules are the central hub for body electronics, and when they fail internally, they create these phantom issues. We installed a VIN-programmed BCM, and in less than 10 minutes, every single issue was resolved. This isn’t just a part replacement; it’s a permanent fix for some of the most frustrating vehicle problems.
Is Your Truck Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ The security system acts up, preventing the vehicle from starting (PassLock issues).
- ✔ An active airbag warning light on the dash, often with DTC B1001 (Option Configuration Error).
- ✔ Unpredictable behavior from windshield wipers or exterior lighting.
- ✔ Multiple communication-related Diagnostic Trouble Codes (DTCs).
This isn’t just a replacement part; it’s peace of mind. Our 2003-2007 Silverado 2500 BCM is meticulously programmed to your vehicle’s specific VIN before it ships. This critical step ensures all factory-installed options work perfectly right out of the box, eliminating the need for expensive dealership programming or specialized scan tools. It’s built to meet or exceed OEM specifications for long-lasting reliability, whether your truck is a daily driver or a heavy-duty workhorse.
Your 5-Minute BCM Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset system memory.
- ✔ Locate the BCM: On most GM trucks and SUVs, the BCM is located under the driver’s side dashboard, just to the left of the steering column. It’s a black box with several large multi-pin connectors.
- ✔ Swap the Module: Carefully unplug the color-coded connectors from the old BCM. They have locking tabs that need to be depressed. Remove the old module (it’s often held by simple clips or a couple of small bolts) and install the new one in its place.
- ✔ Reconnect and Test: Plug the connectors firmly into your new BCM. Reconnect the battery terminal. Start the vehicle and test all functions: lights, locks, windows, wipers, and HVAC to confirm the repair.
- ✔ Post-Install Checks: In some cases, an airbag light may persist. This requires a professional scan tool to perform the ‘Setup SDM Primary Key’ procedure. A ‘Brake Pedal Position Relearn’ may also be needed on certain models.

Frequently Asked Questions
Do I need to send my old BCM back? Is there a core charge?
No. We do not require a core return for this module. You can keep your old part, which simplifies the process for you.
Is this part truly plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping, so it’s ready for installation without needing a trip to the dealership. In rare cases, a post-install procedure like an airbag system sync may be required if a related warning light appears.
What tools do I need for installation?
For most applications, you’ll only need a basic socket or screwdriver to access the module. No special programming tools are required for the installation itself.
My airbag light is on. Will this BCM fix it?
A faulty BCM is a very common cause of an airbag light with a B1001 code. Replacing it often resolves the issue. However, if the light stays on after installation, it means the new BCM needs to be synced with the airbag’s SDM module using the ‘Setup SDM Primary Key’ procedure, which requires a professional-grade scan tool.
How do I provide my VIN for programming?
You will be prompted to enter your vehicle’s 17-digit VIN during the checkout process. Please double-check it for accuracy to ensure perfect programming.
Will this fix my truck not starting?
It can. The BCM is integral to the PassLock security system on these GM vehicles. If the BCM fails, it can prevent the engine from starting. If you’re experiencing a no-start condition along with other electrical symptoms, this is a very likely solution.
