Fix Your Truck’s Electrical Headaches for Good
Is your 2003-2007 GMC Sierra 3500 or other GM truck acting possessed? Flickering lights, a dead A/C blower, or power windows with a mind of their own are more than just annoying—they’re often signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s comfort and security electronics, a faulty BCM can cause a cascade of frustrating, hard-to-diagnose issues. This replacement module, part number 10367690, is the definitive solution to restore order. Through our expert cloning service, we transfer the critical data from your original BCM to this replacement unit, ensuring a true plug-and-play fix without a costly trip to the dealership.
Case Study: A Tricky Diagnosis
A customer brought in a 2006 Silverado 2500HD with a baffling combination of problems: the radio would cut out, the driver’s side window wouldn’t work, and the airbag light was on. They had already replaced the window switch and checked fuses with no luck. After connecting my scanner, I saw a handful of communication codes and a specific BCM internal fault (DTC B1001). In my shop, I’ve seen this exact pattern on hundreds of these GMT800 trucks. The root cause is often failing solder joints or internal corrosion on the BCM’s circuit board. Instead of a wild goose chase, we performed a cloning service on a replacement 2003-2007 Sierra 3500 BCM. The result? All electrical functions were immediately restored, and the communication codes vanished. It’s a classic failure that a simple part swap can solve perfectly.
Is Your Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Unresponsive or intermittent power windows, door locks, or interior lights.
- ✔ The security system acts erratically, preventing the truck from starting (Passlock issues).
- ✔ HVAC controls are inoperative, or the blower motor only works on some speeds or not at all.
- ✔ An illuminated airbag light, often accompanied by Diagnostic Trouble Code (DTC) B1001 (Option Configuration Error).
- ✔ Strange electrical behavior, such as the radio turning off or the horn honking randomly.
- ✔ Communication errors with other modules on the vehicle’s data network.
Your 5-Minute BCM Swap Guide
Installing your cloned BCM is a straightforward process that most DIYers can complete in minutes. No complex wiring or programming is required.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents short circuits and helps reset related modules.
- Locate the BCM: On most GM trucks and SUVs of this era, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black plastic box with several large multi-pin connectors.
- Swap the Module: Carefully unplug the electrical connectors from your old BCM. They have release tabs that need to be pressed. Once disconnected, unbolt or unclip the module from its bracket and remove it.
- Install the New BCM: Seat the replacement module into the bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: windows, locks, lights, wipers, and the HVAC system.
Post-Installation Note: In some cases, especially if the airbag light was on, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag system. Similarly, a Brake Pedal Position relearn might be required. These are simple procedures for any qualified technician.

Frequently Asked Questions
What is a ‘Cloning Service’ and why do I need it?
Cloning is a process where we transfer the vehicle-specific data—like your VIN, mileage, and option content—from your original BCM to the replacement unit. This makes the new module a perfect digital copy of the old one, allowing it to work instantly without requiring expensive and time-consuming dealership programming.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, you must ship your original module to us. We will perform the data transfer and ship both your original module and the ready-to-install replacement back to you. We do not keep your original part.
Will this finally fix my airbag light?
If the airbag light is caused by a BCM-related code like B1001, this will resolve the root cause. However, after installation, you may need a technician with a bi-directional scan tool to perform the ‘Setup SDM Primary Key’ procedure to clear the light and sync the systems.
What tools are required for installation?
Basic hand tools are all you need. Typically, a small socket set or a nut driver (often 7mm or 10mm) to remove the mounting bolts and a flat-head screwdriver to gently release connector tabs is sufficient. The entire job usually takes less than 10 minutes.
Is there a core charge for this part?
No, there is no core charge. Our service is structured around cloning your original module, so we always return your original part to you along with the programmed replacement. You don’t have to worry about core returns or fees.
