Finally Solve Your Yukon’s Frustrating Electrical Problems
Are you tired of dealing with baffling electrical issues in your 2003-2006 GMC Yukon? One day the power windows work, the next they don’t. Maybe the HVAC controls have a mind of their own, or a persistent airbag light refuses to go away. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). This module is the electronic nerve center for your vehicle’s comfort and convenience features. When it fails, it can create a cascade of unpredictable problems. Our replacement BCM, part number 15136225, is the definitive solution, offered with a professional cloning service that makes installation a true plug-and-play experience.
A Technician’s Notebook: The Case of the Haunted Yukon
I remember a 2005 Yukon XL that came into my bay with a list of complaints that sounded like a ghost was in the machine. The radio would randomly shut off, the dome lights would flicker, and the security light would stay on, sometimes causing a no-start condition. The owner had already replaced the battery and checked the grounds. After hooking up my scan tool, I saw a handful of communication codes, including the notorious BCM code B1001. Instead of just installing a new module that would require a trip to the dealer for expensive programming, we provided a cloned BCM. We transferred all the original data to the replacement unit. The customer plugged it in himself in his driveway, and every single issue was resolved instantly. That’s the power of a properly prepared module.
Is Your Yukon Exhibiting These Common BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the culprit. This is the exact solution needed for your 2003-2006 Yukon BCM repair.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ An active airbag warning light, often with Diagnostic Trouble Code (DTC) B1001.
- ✔ Erratic interior or exterior lights (e.g., headlights, dome lights, dash lights).
- ✔ Security system faults, including no-start situations where the engine won’t crank.
- ✔ Inconsistent windshield wiper operation.
Your 5-Minute Path to a Perfect Repair
Our cloning service eliminates the need for dealership intervention. The module arrives ready to install, pre-loaded with your Yukon’s specific data. The physical installation is straightforward for any DIY enthusiast or professional mechanic.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most 2003-2006 Yukons, the BCM is located under the driver’s side dashboard, to the left of the steering column.
- Swap the Module: Carefully disconnect the electrical connectors from your old BCM. They have release tabs that need to be pressed. Remove the old module and install the new one in its place.
- Connect and Test: Reconnect the electrical harnesses to the new BCM. Ensure they click securely into place. Reconnect the battery terminal.
- Verify the Fix: Start your Yukon and test all the functions that were previously malfunctioning—windows, locks, HVAC, lights, etc.
Important Post-Installation Information
While our cloning service handles the primary programming, some vehicle systems may require a quick sync after installation. If your airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary. These are simple procedures for any qualified shop. Our service ensures you won’t need the dealer for the main, most expensive programming steps.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is a process where we transfer the exact software, VIN, and key-related data from your original BCM to the replacement unit. This makes the new module a perfect digital copy, ensuring it communicates seamlessly with your vehicle’s other computers without needing any additional programming.
Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a very common cause of the B1001 code. Replacing it with our cloned module typically resolves the root cause. However, after installation, you may need a scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light, as the systems need to re-sync.
Do I need to take my truck to the dealer after installation?
No. Our cloning service is specifically designed to bypass the need for dealer programming, saving you significant time and money. The module arrives ready for installation.
Where is the BCM located on my 2005 Yukon?
The Body Control Module on a 2003-2006 GMC Yukon is typically found under the driver-side dashboard, near the steering column. It’s a black box with several large electrical connectors.
What do I do with my old BCM? Is there a core charge?
There is no core charge. After you send us your original module for the cloning service, we return it to you along with your newly programmed replacement unit. You can keep it or dispose of it as you wish.
