Tired of Chasing Electrical Gremlins in Your GM Truck?
If you’re dealing with a frustrating mix of electrical issues in your 2002-2006 Chevrolet Avalanche 2500, you’re not alone. One day the power windows work, the next they don’t. The HVAC blower motor has a mind of its own, and a mysterious airbag light stays on. These aren’t separate problems; they’re classic signs of a failing Body Control Module (BCM). The BCM is the electronic nerve center for your truck’s comfort and security features, and when it starts to go, it can create chaos. This replacement BCM, part number 10367690, is the definitive solution to restore order and reliability to your vehicle.
The Power of a Perfect Clone: Why Our Service is Better
Forget the hassle and expense of a dealership visit. Our unique Cloning Service makes this repair a true plug-and-play experience. Here’s how it works: you send us your original BCM, and we perform a full data transfer to this replacement unit. We copy everything—your vehicle’s VIN, mileage, and specific RPO codes for options like keyless entry and security settings. This means the module that arrives at your door is an exact electronic duplicate of your original, ensuring every function works perfectly from the moment you plug it in. There are no additional programming or calibration steps needed for most vehicles.
A Technician’s Notebook: The Case of the Water-Damaged BCM
I had a 2005 Silverado 2500HD in the bay last month with the strangest collection of symptoms. The radio would cut out, the driver’s side door lock was dead, and the customer complained his battery was draining overnight. A scan showed a dozen intermittent communication codes. After checking the usual suspects, I pulled the BCM from under the driver’s dash. Sure enough, the tell-tale green corrosion from water intrusion was visible on the pins. A leaking windshield seal had allowed water to drip directly onto the module over time, shorting out internal circuits. A replacement 2002-2006 Avalanche 2500 BCM (the same part family) with our cloning service had him fixed and back on the road the next day, with no more parasitic draw or random glitches.
Is Your Truck Showing These Telltale Signs?
- ✔ Unresponsive or intermittent power windows, door locks, or mirrors.
- ✔ HVAC system failures, such as a blower that won’t turn on or can’t be controlled.
- ✔ An active airbag warning light, often with Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system alerts or a no-start condition where the engine cranks but won’t fire.
- ✔ Interior or exterior lights that stay on, flicker, or won’t work at all.
- ✔ False warnings on the driver information center (DIC).
Your 5-Minute Path to a Fully Functional Truck
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the Module: On most GM trucks and SUVs like the Avalanche, the BCM is located under the driver’s side of the dashboard, near the steering column.
- ✔ Remove the Old BCM: The module is typically held in place by plastic clips or a few small bolts. Carefully unplug the electrical connectors (they have locking tabs you’ll need to press) and remove the old unit.
- ✔ Install the New BCM: Plug the connectors firmly into your new, cloned BCM and secure it back in its mounting location.
- ✔ Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions—windows, locks, wipers, lights, and HVAC—to confirm the repair was successful.
Post-Installation Notes
While our cloning service handles the vast majority of programming, some vehicle systems may require a quick sync. If your airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a Brake Pedal Position relearn might be required on some models. We also handle the entire process with no core charge, and your original module is always returned to you.

Frequently Asked Questions
How does the cloning service work?
After you place your order, you’ll receive instructions to ship your original BCM to us. Our technicians will extract the unique data from your module and flash it onto the replacement unit. We then ship both your original module and the ready-to-install replacement back to you.
Do I need to get this programmed by a dealer?
No. The cloning service completely eliminates the need for dealer programming, saving you time and money. It’s designed to be a true plug-and-play solution.
What if my airbag light is on after installation?
In some cases, the new BCM needs to be electronically introduced to the airbag system (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed with a professional-grade scan tool.
Is there a core charge for this part?
No, there is no core charge. Since we require your original module for the cloning process, we simply return it to you along with the newly programmed unit.
What is the warranty on this BCM?
