Tired of Your Truck’s Electrical Gremlins?
If your 2003-2007 GMC Sierra 2500 is suffering from bizarre electrical issues like flickering lights, a non-responsive HVAC system, or power windows with a mind of their own, you’ve likely met the common point of failure: a faulty Body Control Module (BCM). As the central hub for your truck’s body electronics, a failing BCM can cause a cascade of frustrating problems. This replacement BCM, part number 10367690, is the definitive solution to restore full functionality and peace of mind.
What makes our module different is our expert Cloning Service. Instead of sending you a generic module that requires expensive and time-consuming dealership programming, we transfer the specific data from your original BCM directly onto this replacement unit. This ensures seamless integration with your truck’s existing systems, including the VIN and security information, for a true plug-and-play installation. Get your truck’s features working reliably again without the dealership hassle.
Case Study: A Tricky Diagnosis
I once had a 2005 Sierra 2500 HD in my bay that was a real head-scratcher. The owner complained of an intermittent no-start condition coupled with the security light flashing randomly. He’d already spent hundreds at another shop that couldn’t pinpoint the problem. After hooking up my scanner, I saw communication loss codes with the BCM. A quick check of the main harness revealed no damage. The issue was internal to the module itself—a common problem on these GMT800 platforms after years of heat cycles. With our cloned BCM, the truck fired up on the first try and the security light was gone. It’s a fix that saves both time and money.
Is Your Sierra Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Intermittent or total loss of HVAC blower motor or climate controls.
- ✔ The airbag warning light is illuminated, often with a DTC like B1001 (Option Configuration Error).
- ✔ Power accessories like windows, door locks, or mirrors work sporadically or not at all.
- ✔ Vehicle security system malfunctions, causing no-start conditions or false alarms.
- ✔ Inconsistent operation of interior dome lights or exterior lighting.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs) stored in the system.
A Straightforward Guide to Installation
One of the best parts of our cloning service is how simple the installation becomes. You can have your truck back in working order in minutes. No special tools are required for the physical swap.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the Module: On most Sierra/Silverado models, 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 BCM: Carefully unplug the electrical connectors from your old BCM. Release the mounting tabs and remove the module. Position the new, cloned module and securely plug in all connectors.
- 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 Checks: In some cases, an airbag light may require a ‘Setup SDM Primary Key’ procedure with a compatible scan tool. Similarly, a Brake Pedal Position relearn may be needed.

Frequently Asked Questions
What exactly is the ‘Cloning Service’?
Our cloning service is a process where we transfer all the critical vehicle-specific data—like your VIN, mileage, and security settings—from your original BCM to the replacement unit. This makes the new module a perfect electronic match for your truck, eliminating the need for dealership programming.
Do I need to send you my original BCM?
Yes. For the cloning process to work, you must send us your original module after placing your order. We will perform the service and ship both your original and the ready-to-install replacement back to you.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. It’s a quick process for any competent repair shop.
Is there a core charge for this part?
No, there is no core charge. We always return your original module along with the newly programmed replacement, so you can keep it for your records or dispose of it as you see fit.
Will this fix my intermittent no-start problem?
If your no-start issue is related to the vehicle’s anti-theft or security system (Passlock/VATS), which is controlled by the BCM, then yes, this is a very common fix. A faulty BCM often fails to recognize the key, preventing the engine from starting.
