Tired of Your GM Vehicle’s Mysterious Electrical Problems?
As a technician with over two decades of experience, I’ve seen it all. A 2015 GMC Yukon comes into the bay with a laundry list of bizarre symptoms: the radio works one minute and not the next, the power windows have a mind of their own, and the security light is flashing, causing an intermittent no-start. The owner is frustrated, having already replaced the battery and checked fuses. This is a classic case of a failing Body Control Module (BCM). The BCM is the central hub for your vehicle’s body electronics, and when it goes bad, it can feel like your truck is possessed.
This isn’t just a part; it’s a complete solution. We offer a professionally programmed Body Control Module, specifically for your vehicle, by cloning the data from your original unit. This process transfers all the critical, vehicle-specific information—like VIN, mileage, and options—to this replacement module. The result? You get a BCM that is ready for installation right out of the box, saving you from the expensive programming and calibration fees at a dealership. This service is designed for part number 13594769 and is also a direct replacement for several other GM part numbers.
From the Diagnostic Bay: The Case of the Confused Silverado
I remember a 2014 Silverado 1500 that was a real head-scratcher for a local shop. They’d call me for a second opinion. The truck would randomly honk its horn when locked, the dome lights would stay on, and it was throwing a U0140 code (Lost Communication With Body Control Module). They suspected a wiring issue, but after hours of tracing circuits, everything checked out. I suggested they send me the BCM. Once we received it, we performed our cloning service onto one of our tested modules. They installed it, and just like that, every single ghost in the machine was gone. It wasn’t the wiring; it was the BCM’s internal logic that had failed. This service saved them and their customer hundreds in diagnostic time and dealership costs.
Is Your GM Vehicle Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is your likely solution:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The anti-theft or security system light is on, preventing the engine from starting.
- ✔ The radio or infotainment system is malfunctioning.
- ✔ False warnings appearing on the instrument cluster (e.g., “Service 4WD”).
- ✔ Communication-related Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or B1325.
- ✔ A/C and heater controls not responding correctly.
Your Straightforward BCM Installation Guide
Our cloning service handles the complicated programming. All you need to do is swap the module. For a 2015 GMC Yukon, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. Wait a few minutes for the system capacitors to discharge.
- Locate the BCM: On most compatible trucks and SUVs, you’ll find the BCM mounted under the dash, to the left of the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM in the same location and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair.
Important Post-Installation Notes
While our cloning makes this process as simple as possible, some GM vehicles may require a final handshake between modules. If your airbag light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. Additionally, some models might require a “Brake Pedal Position Relearn” to ensure perfect function of brake lights and stability control. Always consult a factory service manual for vehicle-specific details.

Frequently Asked Questions
What exactly is the cloning service?
You send us your original, faulty BCM. We then use specialized equipment to read all the vehicle-specific programming and security data from it and write that exact data onto this fully tested replacement BCM. This ensures it’s a perfect match for your vehicle’s configuration.
Does this BCM require any additional programming?
No. The cloning service means the module arrives at your door pre-programmed and ready for installation. This allows you to skip a trip to the dealer for expensive programming.
Where is the BCM located on my 2015 Yukon or Silverado?
It is typically found under the driver’s side dashboard, attached near the steering column. You may need to remove a plastic trim panel to access it.
What if my airbag light comes on after I install it?
This is a possibility on some GM models. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back for a core charge?
No, there is no core charge for this item. Our service requires your original module for the data cloning process, after which you can keep it.
How long does the programming service take?
Once we receive your original BCM, the cloning and testing process is typically completed within 1-2 business days. We will then ship the programmed replacement module back to you and provide tracking information.
