Tired of Unpredictable Electrical Problems in Your GMC Yukon?
If you’re dealing with a 2003-2006 GMC Yukon that seems to have a mind of its own—windows that won’t roll down, a climate control system that’s gone haywire, or a persistent security light that prevents it from starting—you’ve likely met the common culprit: a failing Body Control Module (BCM). As the central command for your truck’s comfort and convenience features, when the BCM goes bad, it can cause a cascade of frustrating and seemingly unrelated issues. This isn’t just an inconvenience; it can affect your vehicle’s safety and security.
Instead of risking a generic, off-the-shelf module that requires an expensive trip to the dealership for programming, we offer a precise and reliable solution. This is a direct-fit replacement for part number 10383536, and our expert Cloning Service makes the installation process seamless. We transfer the critical data from your original BCM to this replacement unit, ensuring it works perfectly with your Yukon’s specific configuration right out of the box.
A Technician’s Notebook: The Case of the Haunted Yukon
A customer brought in his ’05 Yukon XL, complaining of what he called “automotive ghosts.” The radio would switch off, the dome lights would flicker while driving, and the driver’s side power window had stopped working entirely. His scan tool showed a dozen communication codes (U-codes) and a B1001 for the airbag system. In my 20+ years in the bay, I’ve seen this exact pattern hundreds of times on these GMT800 platforms. It’s almost always a failing BCM. The internal solder joints and relays weaken over time, causing intermittent connections. We performed our cloning service on a replacement 2003-2006 Yukon BCM, and within an hour of the part’s arrival, the truck was back to 100% functionality—no more ghosts, no more warning lights.
Is Your Yukon Showing These Telltale Signs?
- ✔ The security or anti-theft light stays on, causing a no-start condition.
- ✔ Power windows, door locks, or mirrors work intermittently or not at all.
- ✔ The HVAC and climate controls are unresponsive, or the blower motor is stuck on or off.
- ✔ Interior and exterior lights (headlights, taillights, dome lights) flicker or fail to operate correctly.
- ✔ The airbag warning light is illuminated, often with a DTC like B1001.
- ✔ Wipers operate erratically or won’t turn off.
- ✔ A host of communication Diagnostic Trouble Codes (DTCs) are present.
Your Step-by-Step Installation Guide
Installing your cloned BCM is a straightforward job that most DIYers can complete in under 15 minutes with basic tools. Here’s how to get it done right:
- Safety First: Before you begin, disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the vehicle’s electronic systems.
- Locate the BCM: On most 2003-2006 Yukon models, the Body Control Module is located under the driver’s side of the dashboard, to the left of the steering column. It’s a black plastic box with several large electrical connectors.
- Remove the Old Module: Carefully unplug the color-coded electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unclip the module from its mounting bracket.
- Install the Cloned BCM: Snap the new, cloned module into the mounting bracket and firmly reconnect all the electrical harnesses. Ensure each connector clicks into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, wipers, and HVAC—to confirm the repair was successful.
- Post-Installation Checks: In some cases, an “Airbag System Sync” or “Brake Pedal Position Relearn” may be required if you see related warning lights. This is done with a professional scan tool and syncs the new BCM with the other vehicle modules.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a “Cloning Service”?
Cloning is a process where we transfer the exact software, VIN, mileage, and key-related data from your original, failing BCM to this replacement unit. This makes the new module a perfect digital copy of the old one, eliminating the need for dealership programming and ensuring all your vehicle’s options work correctly.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, you must send us your original module after placing your order. We perform the service and ship both your original module and the ready-to-install cloned replacement back to you promptly.
What happens if the airbag light comes on after installation?
This is uncommon but can happen. It means the BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A repair shop with a professional scan tool can perform the “Setup SDM Primary Key in BCM” procedure in a few minutes to clear the light.
Is there a core charge for this part?
No, there is no core charge. We require your original module to perform the cloning service, and we always return your original part to you along with the newly programmed replacement.
