Tired of Your Truck’s Mysterious Electrical Problems?
If your 2014 GMC Sierra 1500 is acting possessed—with flickering lights, a dead instrument cluster, power windows that have a mind of their own, or a frustrating no-start condition—you’re not alone. The Body Control Module, or BCM, is the central command center for your truck’s body electronics. When it starts to fail, it can create a cascade of baffling and intermittent issues that are a nightmare to diagnose. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
Our solution bypasses the expensive and time-consuming trip to the dealership. We provide a fully programmed 2014 Sierra 1500 BCM that is a direct, plug-and-play replacement. Through our professional cloning service, we transfer all the critical vehicle-specific data from your original BCM to this replacement unit. This means no additional programming or key relearning is required on your end. You get a reliable fix that restores your truck’s functionality right out of the box.
From the Diagnostic Bay
I remember a 2014 Sierra that came into the shop with the strangest set of symptoms I’d seen in a while. The owner said his radio would randomly shut off, the dome light would stay on, and occasionally, the truck wouldn’t recognize his key fob. He’d already replaced the battery and checked all the fuses. We hooked up the scanner and found a slew of communication codes (U-codes), all pointing to a network issue. After ruling out wiring problems, we focused on the BCM. These modules are the traffic cops of the vehicle’s data network. A failing BCM is like a traffic cop who has fallen asleep—chaos ensues. By cloning his original module to one of our tested units, we had him back on the road in an afternoon, with all the electrical gremlins gone for good.
Is Your Truck Plagued by These Electrical Gremlins?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, a faulty BCM is the likely culprit:
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system light is on, or the alarm randomly triggers.
- ✔ The vehicle won’t start, but the battery and starter are good.
- ✔ The instrument cluster is dead or displays incorrect information.
- ✔ Multiple communication Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or U0100.
- ✔ Wipers or radio turning on and off by themselves.
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is a simple swap. Our cloning service handles all the complex software work for you. Just follow these steps:
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the BCM: On most 2014 Sierra 1500 models, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black box with several large electrical connectors.
- Remove the Old Module: Carefully unplug all the wiring harnesses from the original BCM. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the wiring harnesses, making sure each one clicks firmly into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, and radio—to confirm the repair.
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a quick sync-up after the BCM is replaced. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the airbag system with the new BCM and can be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, the traction control or ABS light may appear. A brake pedal position sensor relearn procedure may be necessary to ensure all safety systems are calibrated correctly.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. Specific procedures can vary slightly by vehicle trim and options.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the unique vehicle data and transfer it to the replacement module. We then ship the ready-to-install BCM back to you.
Do I need to program this module?
No. The entire point of our service is to handle the programming for you. The BCM you receive will be plug-and-play, with all your vehicle’s original settings and key information already loaded onto it.
What if my original BCM is completely dead or won’t communicate?
In many cases, even if the BCM is failing, we can still retrieve the necessary data from the memory chip. Please contact us before ordering if your module is severely damaged by water or fire, as data recovery may not be possible in those rare instances.
Is there a core charge?
No, there is no core charge. You are not required to send your original module back to us after the repair, but we do need it initially to perform the cloning service.
Will this fix my specific problem?
This part is a direct solution for issues caused by a faulty BCM. If you’re experiencing multiple, unrelated electrical problems like those listed above, the BCM is the most probable cause. Proper diagnosis is always recommended.
