Tired of Unpredictable Electrical Problems in Your GM Vehicle?
As a technician with over two decades of experience, I’ve seen it all. One minute your power windows work, the next they don’t. Your dash lights flicker randomly, the radio acts possessed, or worse, your car refuses to start. These aren’t just annoyances; they’re classic symptoms of a failing Body Control Module (BCM), the central nervous system for your vehicle’s electronics. This isn’t a part you can just swap out. It contains vital security and vehicle-specific data. Our professional cloning service for this 2014-2015 Spark BCM is the definitive, hassle-free solution.
We take the guesswork and exorbitant dealership costs out of the equation. Simply purchase this service, send us your original BCM, and we’ll transfer all its critical data to this fully tested replacement unit. When you get it back, it’s ready for installation, seamlessly restoring your car’s functionality. It’s the most reliable and cost-effective way to get back on the road with confidence.
A Technician’s Notebook: The Case of the Confused Cruze
A customer brought in a 2014 Cruze with a laundry list of bizarre issues: the horn would honk when turning right, the interior lights wouldn’t turn off, and the key fob worked intermittently. They had already replaced the battery and checked all the fuses. Diagnostics pointed towards a communication breakdown. After pulling the BCM, I noticed subtle signs of corrosion on one of the connector pins—a common issue from moisture ingress near the kick panel. By cloning his original BCM data to a clean, tested unit like this one, we solved every single ghost in his machine in one afternoon. This is a fix I’ve performed hundreds of times on various GM models, and it’s almost always the BCM at fault.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system preventing the car from starting (blinking security light).
- ✔ Inconsistent or non-functional key fob and remote start.
- ✔ False warnings appearing on the instrument cluster (e.g., “Service Airbag”).
- ✔ Communication error codes, such as U0100, U0140, or other “U” series codes.
Your BCM Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2014-2015 Spark, the BCM is typically found at the base of the driver-side A-pillar, often behind a kick panel. Consult your service manual for the exact location on other compatible models.
- ✔ Remove Trim Panels: Carefully remove any plastic trim or kick panels necessary to access the module.
- ✔ Disconnect and Remove: Unplug all electrical connectors from the old BCM. They have release tabs that must be pressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your newly programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- ✔ Reconnect Battery: Reattach the negative battery terminal.
- ✔ Test Functionality: Start the vehicle and test all body functions – windows, locks, lights, radio, etc. – to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a near plug-and-play repair, some vehicle systems may require a handshake with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the BCM and is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to return your original module to us after the service. There is no core fee.
Disclaimer: Vehicle systems vary. Always have a factory service manual for your specific model available for reference.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with shipping instructions. You send us your original BCM. We then transfer 100% of the data to the replacement unit and ship it back to you, typically within one business day of receiving yours.
Will I need to have this programmed by a dealer?
No. Our cloning service makes the replacement BCM plug-and-play. It will have all your vehicle’s original data, including the VIN and key information, so no additional programming is required.
Is this a guaranteed fix for my car’s electrical problems?
If your vehicle is exhibiting the common symptoms of BCM failure (erratic lights, locks, windows, no-start), this is the most likely solution. Proper diagnosis is key, but a faulty BCM is a very common point of failure in these vehicles.
What if my original BCM is completely dead or not communicating?
In most cases, we can still retrieve the necessary data even from a non-communicating module. If for some reason the data is completely unrecoverable, we will contact you to discuss options and provide a full refund if needed.
What is the part number for this 2014-2015 Spark BCM?
The primary part number is 13586273, but it also directly replaces several others, including 13584695, 13580697, and 13588447. Please check the full list to ensure compatibility.
