Tired of Chasing Electrical Gremlins in Your GM Truck?
If you’re dealing with baffling electrical issues in your 2003-2007 GMC Sierra 3500 or another compatible GM vehicle, the Body Control Module (BCM) is often the culprit. As the central hub for your truck’s body electronics, a failing BCM can cause a cascade of problems, from non-functional power windows and erratic climate controls to frustrating no-start conditions. This replacement BCM, part number 10383536, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
Unlike a standard replacement that requires a trip to the dealership for expensive programming, this module comes with our expert Cloning Service. We transfer the critical data from your original BCM to this replacement unit, ensuring it’s a true plug-and-play part, perfectly matched to your vehicle’s specific configuration. This process preserves all your original settings and security information, saving you time, money, and headaches.
Case Study: A Tricky Diagnosis
A customer brought in a 2006 Silverado 2500 with a strange mix of symptoms: the radio would turn on and off by itself, the driver’s side power window worked intermittently, and the airbag light was on with a DTC B1001 (Option Configuration Error). They had already replaced the window switch and checked fuses. In my shop, I’ve seen this exact pattern dozens of times. We suspected the BCM. After connecting a scan tool, we confirmed communication errors with the module. Instead of a costly new unit and dealer programming, we performed our cloning service on a replacement BCM. The new module was installed in minutes, and every single electrical issue was resolved instantly, including the B1001 code, because the vehicle’s correct configuration was cloned over.
Is Your GM Truck Showing These Electrical Faults?
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ HVAC blower motor not working or climate controls are unresponsive.
- ✔ The security system is malfunctioning, leading to a no-start or crank-no-start condition.
- ✔ An airbag warning light is illuminated, often with a related BCM diagnostic trouble code like B1001.
- ✔ Erratic behavior from your wipers, horn, or other electronic accessories.
- ✔ Communication errors with other modules on the vehicle’s data network.
A Straightforward Guide to Installation
Replacing your BCM is a simple job that most DIY enthusiasts can complete in under 10 minutes. Our cloning service makes it a direct swap with no dealer visit required.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most GM trucks and SUVs like the Sierra and Silverado, the BCM is located under the driver’s side dashboard, near the steering column. On Express and Savana vans, it’s typically behind the center dash panel.
- Remove and Replace: Carefully unplug the electrical connectors from your old BCM. They have locking tabs that need to be depressed. Remove any mounting screws or clips, and swap in the new module. Reconnect the connectors securely.
- Reconnect Power: Reattach the negative battery terminal.
- Post-Installation Checks: Start the vehicle and test all body functions—lights, locks, windows, HVAC, etc. In some cases, an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ may be needed if related warning lights appear. This is typically done with a professional-grade scan tool.

Frequently Asked Questions
What is the ‘Cloning Service’?
Cloning is a process where we transfer the essential programming, security data, and vehicle-specific options from your original BCM directly onto the replacement unit. This makes the new module a 100% plug-and-play solution, eliminating the need for dealership programming.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, you must send us your original Body Control Module after placing your order. We will perform the service and ship both your original and the newly programmed replacement back to you.
Is there a core charge?
No, there is no core charge. We always return your original module along with the replacement, so you don’t have to worry about extra fees or core returns.
My airbag light came on after installation. What should I do?
This can occasionally happen. It requires a ‘Setup SDM Primary Key in BCM’ procedure, which syncs the BCM with the airbag system. This must be performed using a professional diagnostic tool. It’s a quick procedure for any qualified technician.
Will this fix my specific problem?
This module is the direct solution for failures within the BCM itself. While it resolves the vast majority of the symptoms listed, always ensure your vehicle’s wiring and related components are in good condition. A proper diagnosis is key to a successful repair.
What is the warranty on this part?
This BCM is backed by our comprehensive one-year warranty, giving you peace of mind and confidence in your repair.
