Restore Full Electrical Function to Your 2003-2006 GMC Yukon
Are you chasing down frustrating electrical gremlins in your GMC Yukon? Intermittent power windows, a possessed radio, flickering lights, or a security system that randomly prevents your truck from starting are all classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can make driving a daily headache. This replacement BCM, part number 15116066, is the definitive solution for restoring order and reliability to your vehicle’s essential functions.
We take the guesswork and extra cost out of the repair with our professional Cloning Service. Simply send us your original BCM, and we will transfer all of its critical, vehicle-specific data to this replacement unit. This ensures 100% compatibility with your Yukon’s existing systems, including keys and security settings, without requiring a costly trip to the dealership for programming. It’s a true plug-and-play fix designed for both professional technicians and DIY-savvy owners.
Case Study: The Yukon with a Mind of Its Own
A customer brought in a 2005 Yukon Denali with a baffling set of symptoms. The dash lights would flicker, the radio would cut out, and occasionally, the power locks would cycle on their own. They’d already replaced the battery and checked the alternator. After plugging in my scanner, I saw a dozen communication codes pointing to the BCM. In my 20+ years of experience, these GM BCMs often fail due to internal circuit board corrosion or failing solder joints, causing unpredictable behavior. By installing a cloned 2003-2006 Yukon BCM, we restored stable power to all accessories and eliminated the communication faults in under 10 minutes. The customer was back on the road with a reliable vehicle, saving hundreds compared to a dealership repair.
Is Your GM Truck or SUV Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors not working or operating erratically.
- ✔ HVAC controls are unresponsive, or the blower motor works intermittently.
- ✔ The security system malfunctions, causing a no-start condition (Security light on).
- ✔ The airbag warning light is illuminated, often with a DTC like B1001 (Setup SDM Primary Key in BCM).
- ✔ Interior dome lights or exterior lights (headlights, taillights) fail to work correctly.
- ✔ The instrument cluster displays false warnings or acts strangely.
Your 5-Minute Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and help reset system memory.
- ✔ Locate the BCM: On most 2003-2006 Yukon and similar GM models, the BCM is located under the driver’s side dashboard, just to the left of the steering column.
- ✔ Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, the module can be unclipped or unbolted from its bracket.
- ✔ Install the New BCM: Connect the electrical harnesses to your new, cloned BCM. Ensure they click securely into place. Mount the module back onto its bracket.
- ✔ Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions: lights, windows, locks, wipers, and HVAC to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, 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. In some cases, a “Brake Pedal Position Relearn” may also be necessary. These are simple procedures for any qualified shop. And remember, there is no core charge—we return your original module with your newly cloned replacement.

Frequently Asked Questions
What is a “Cloning Service” and why do I need it?
Cloning is a process where we transfer the exact software, VIN, mileage, and key information from your original BCM to the replacement unit. This makes the new module a perfect digital copy, allowing it to work in your vehicle immediately without any additional programming from a dealer, saving you time and money.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, we need your original module to extract the necessary data. We will return your original BCM along with your ready-to-install replacement.
Is this BCM difficult to install myself?
Not at all. For most DIYers with basic tools, the installation takes less than 10 minutes. It’s typically located under the driver’s side dash and involves unplugging a few connectors and swapping the module. Our guide above provides the simple steps.
Will this fix my airbag light?
If the airbag light is caused by a BCM communication error (like DTC B1001), this will resolve the root cause. However, after installation, the system may require an “SDM Key Setup” with a pro-level scan tool to sync the airbag module to the new BCM and turn off the light.
What is your warranty and return policy?
This BCM is backed by a one-year warranty against defects. We also handle the cloning service and return your original module to you with the replacement, so there are no core charges or deductions to worry about.
