Tired of Chasing Electrical Gremlins in Your Silverado?
If you’re a 2003-2007 Silverado 1500 owner, you know it’s a tough, reliable truck. But when the Body Control Module (BCM) starts to fail, it can feel like your truck is possessed. One day the power windows don’t work, the next the radio is acting up, or a persistent airbag light won’t go away. These aren’t separate problems; they often point directly to a faulty BCM. As the central command center for your truck’s body electronics, a failing BCM can cause a cascade of frustrating issues. This VIN-programmed Body Control Module, a direct replacement for part number 10367690, is the definitive solution to restore order and get your truck’s features working flawlessly again.
A Technician’s Notebook: The Classic GM BCM Failure
A customer’s 2005 Silverado 1500 came into my shop last month with a laundry list of complaints: the driver’s side window would only work occasionally, the security light was on, and the HVAC blower motor was cutting in and out. He’d already replaced the window switch and checked fuses, getting nowhere. After hooking up my scanner, I saw a B1001 code and several communication errors. This is a textbook case I’ve seen hundreds of times. The internal circuits and solder joints on these original BCMs fail from years of heat cycles and vibration. We swapped in one of our VIN-programmed modules, and within 10 minutes, every single issue was resolved. It’s a simple fix for a complex-looking problem.
Is Your Silverado Showing These Symptoms?
- ✔ The A/C or heater controls have a mind of their own, or the blower motor works intermittently.
- ✔ Your power windows, door locks, or interior lights are unresponsive or act erratically.
- ✔ The dreaded airbag warning light is illuminated on your dash, often with a B1001 diagnostic trouble code.
- ✔ You’re experiencing a no-start condition where the security system seems to be preventing the engine from cranking.
- ✔ The horn honks randomly or the key fob stops working properly.
- ✔ Multiple, seemingly unrelated electrical accessories fail at the same time.
Your 5-Minute Path to a Fully Functional Truck
Replacing the 2003-2007 Silverado 1500 BCM is a job most DIYers can handle with basic tools. Because we pre-program the module to your truck’s VIN, you can skip the expensive trip to the dealership for programming.
- Safety First: Always disconnect the negative terminal from your truck’s battery before starting any electrical work.
- Locate the Module: On most Silverado and Sierra models, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black box with several large electrical connectors.
- Swap the Part: Carefully unplug the electrical connectors from the old BCM. Release the retaining tabs holding the module in place and remove it. Install the new module, ensuring it clicks securely into place, and reconnect all the connectors.
- Reconnect Power: Reattach the negative battery terminal.
- Final Checks (Important): After installation, some vehicles require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to clear the airbag light. A brake pedal position sensor relearn may also be necessary. Consult your service manual or a technician if you are unsure about these final steps.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. It arrives ready for a plug-and-play installation, saving you time and money.
Where is the BCM located on my 2004 Silverado 1500?
The Body Control Module is typically found under the driver’s side dashboard, to the left of the steering column. It’s a black plastic box with multiple wiring harnesses connected to it.
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 this module should resolve the issue, but you may need a capable scan tool to perform the ‘Setup SDM Primary Key’ procedure to turn off the light after installation.
Is this part difficult to install myself?
Not at all. For most people, the installation takes less than 10 minutes and only requires basic hand tools to remove a lower dash panel. The most important part is disconnecting the battery first.
What does ‘no core charge’ mean?
It means you don’t have to send your old, faulty BCM back to us. You can keep it or dispose of it yourself, simplifying the process for you.
What if my part number is slightly different?
This module replaces a wide range of part numbers, including 15116066, 15198116, and 10367690. As long as your vehicle is listed in our compatibility chart, this module will function correctly.
