If you’re battling bizarre electrical issues in your 2014 Corvette—like power windows with a mind of their own, flickering interior lights, or random warning messages on the dash—you’re not alone. These frustrating, hard-to-diagnose problems often point to one central component: a failing Body Control Module (BCM). As the nerve center for your vehicle’s comfort and convenience features, when the BCM falters, it can create chaos. This listing offers a straightforward, reliable solution: a replacement BCM programmed with your vehicle’s exact data, eliminating the need for expensive dealership programming and getting you back on the road with confidence.
A Technician’s Notebook
I remember a 2014 Corvette C7 that came into the shop with a laundry list of intermittent complaints. The owner was at his wit’s end. The radio would randomly shut off, the passenger window wouldn’t respond, and the alarm would occasionally trigger for no reason. We couldn’t find any bad fuses or wiring issues. After hooking up the scan tool, we saw multiple U-series communication codes, indicating a network problem. Experience has taught me that when multiple, unrelated body systems act up simultaneously, the BCM is the prime suspect. It’s the traffic cop for all those signals. We confirmed the BCM was failing internally. Instead of a costly new module and hours of programming at the dealer, we used a cloned unit like this one. The result? A 30-minute swap and every single electrical gremlin was gone. This service saves time, money, and a massive headache.
How Our Simple Mail-In Programming Service Works
Forget about towing your car to the dealer and paying for complex tool setup and programming fees. Our service is designed to be the most direct path to a fix. After you purchase, we’ll provide instructions for you to ship your original BCM to our facility. Once we receive it, our technicians will transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement module. We then ship the fully programmed, plug-and-play unit back to you. It arrives ready for installation, with no further programming required.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system acting up, or the vehicle failing to recognize the key fob.
- ✔ False warning lights on the instrument cluster (e.g., “Service Theft Deterrent System”).
- ✔ In severe cases, a no-start condition where the BCM fails to communicate with the engine computer.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-series codes.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On a 2014 Corvette, the Body Control Module is typically located in the driver’s side of the dash area. On other compatible GM models, it’s often under the steering column or on the firewall. Consult a service manual for your specific vehicle’s location.
- ✔ Remove the Original Module: Carefully unplug the electrical connectors. They have locking tabs that must be depressed to be released. Unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Seat the replacement BCM in the mounting bracket 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 on and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair.
Important Post-Installation Notes
While our programming makes this a plug-and-play solution, some GM vehicles may require a simple relearn procedure for specific systems to sync with the new BCM. This is normal and can often be done with a high-end scan tool.
- 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 new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why is your cloning service better than buying a new BCM from the dealer?
Our service saves you significant money and hassle. A new dealer BCM requires expensive, vehicle-specific programming with proprietary tools. Our process transfers your vehicle’s original data, making the replacement module plug-and-play right out of the box, with no additional programming fees.
Do I need to send my original BCM?
Yes. We need your original module to extract the unique data required to program the replacement. This ensures perfect compatibility with your vehicle’s existing systems and security information. We will contact you with shipping instructions after your purchase.
Is there a core charge?
No, there is no core charge. You can keep your original, non-working module after we have completed the programming service.
Will this fix my specific problem?
This module will resolve issues directly caused by a faulty BCM. If you are experiencing multiple, unrelated electrical problems like those listed in the symptoms section, a failing BCM is the most likely cause. Proper diagnosis is always recommended.
What tools do I need for installation?
For most vehicles, you will only need basic hand tools, such as a socket set or screwdriver, to access and remove the BCM. No special programming tools are required for the installation itself.
