Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating and unpredictable electrical problems in your 2014 Cadillac CTS, Chevrolet Silverado, GMC Sierra, or another compatible GM vehicle? Issues like flickering lights, malfunctioning power windows, a dead instrument cluster, or security system faults often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing and disruptive symptoms. Simply replacing the BCM isn’t an option, as a new unit requires expensive towing and programming at a dealership. We offer a simple, cost-effective, and reliable solution.
This listing is for a replacement BCM, programmed specifically for your vehicle using the data from your original module. This cloning service makes the replacement process straightforward. You send us your original BCM, we transfer all the essential vehicle-specific data—including VIN, mileage, and key programming—to a replacement unit. The BCM you receive back from us will be a true plug-and-play solution, eliminating the need for any additional programming or calibration by a dealer. It’s the fastest and most efficient way to get your vehicle back on the road and operating as it should.
From the Diagnostic Bay
We had a 2015 GMC Sierra 1500 in the shop that was driving the owner crazy. The dash lights would flicker randomly, the radio would cut out, and occasionally it wouldn’t start, just a click. The battery and alternator tested fine. After checking the main power and ground connections, we moved to the BCM under the steering column. At first glance, the module looked fine. But upon disconnecting the main harnesses, we found a single pin on one of the connectors had a faint green tinge—the beginning of corrosion from moisture intrusion. This tiny bit of corrosion was causing intermittent signal loss, creating all the ghost-like electrical problems. It’s a great reminder to always inspect the connectors for damage or corrosion before condemning the module itself. A simple cleaning can sometimes save a lot of time and money.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic interior or exterior lighting; lights may stay on or fail to turn on.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Key fobs not being recognized, or anti-theft system activating incorrectly.
- ✔ Climate control (HVAC) system not responding or blowing air at incorrect temperatures.
- ✔ Radio or infotainment system randomly shutting off or not turning on.
- ✔ Warning messages on the dash such as ‘Service StabiliTrak’ or ‘Service Airbag’.
- ✔ A vehicle that will not start despite having a good battery and starter.
Your Solution: A Programmed 2014 CTS Body Control Module
Our professional programming service is the definitive fix for these issues. By precisely cloning your original module’s data, we ensure the replacement BCM integrates seamlessly with your vehicle’s other electronic systems, such as the Engine Control Module (ECM), Transmission Control Module (TCM), and airbag system (SDM). This process maintains all original factory settings and functionality, providing a reliable and lasting repair without altering your vehicle’s core programming.
How The Process Works:
- ✔ Place Your Order: Purchase this BCM programming service.
- ✔ We Contact You: We will reach out with clear, simple instructions for shipping your original BCM to our facility. Please ensure your contact information is up to date.
- ✔ Ship Your Module: Carefully package and send your original BCM to us.
- ✔ We Program the Replacement: Upon receipt, our technicians will professionally transfer all necessary data from your old module to the replacement BCM.
- ✔ Receive Your Ready-to-Install Part: We ship the fully programmed replacement BCM back to you, typically within 24-48 hours of receiving your original. We will provide tracking information so you know exactly when it will arrive.
Installation and Post-Install Notes
Installation is as simple as removing the old module and plugging in the new one. The BCM is typically located under the driver’s side dash, near the steering column or on the firewall. Always disconnect the vehicle’s battery before starting any work. While our service makes this a plug-and-play part, some GM vehicles may require a simple relearn procedure after installation.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates the new BCM and the SDM (airbag module) need to be re-synced. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary on certain models to ensure proper function of the brake lights and traction control system.
Please consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What is a BCM cloning service?
BCM cloning is a process where we transfer the vehicle-specific software and security data from your original, failing Body Control Module to a fully functional replacement module. This makes the replacement part plug-and-play, avoiding the need for expensive dealership programming.
Why do I need to send in my original BCM?
Your original BCM contains critical data unique to your vehicle, including the VIN, security information for your keys, and specific option configurations. We need this data to properly program the replacement module so it communicates correctly with all other systems in your car.
Is this a true plug-and-play solution?
Yes, in over 95% of cases, the module is completely plug-and-play. You simply install it, and your vehicle’s functions are restored. In rare instances, as noted above, a simple relearn procedure like an airbag system sync may be required.
What happens if my airbag light is on after installation?
If the airbag light comes on, it means the BCM and the airbag module (SDM) need to be electronically re-introduced. A technician with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
How long does the programming service take once you receive my module?
Our standard turnaround time is 24-48 business hours from the time we receive your original BCM. We then ship the programmed replacement back to you promptly.
Will this fix my specific problem?
This service will correct any issues directly caused by a faulty BCM. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before ordering.
