Tired of Electrical Gremlins in Your GM Vehicle?
If you’re dealing with flickering lights, power windows that have a mind of their own, a security system that won’t cooperate, or a dashboard that lights up with random warnings, you’re likely facing a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can turn your reliable truck or car into a source of daily frustration. The dealership solution often involves a brand new module and several hours of expensive programming. We offer a smarter, more direct path to getting your vehicle back in order.
This is a replacement Body Control Module, compatible with part number 13594768 and others, that comes ready for installation through our professional cloning service. By transferring the vital data from your original BCM to this replacement unit, we eliminate the need for any additional programming or key relearning procedures. It’s a true plug-and-play fix designed to save you time, money, and headaches. This service is essential for restoring the functionality you depend on every day.
A Technician’s Notebook
I remember a 2014 Sierra 1500 rolling into my bay last month with a laundry list of bizarre symptoms. The owner said his radio would shut off randomly, the dome light would stay on, and sometimes the truck wouldn’t recognize his key fob. A scan tool showed a slew of communication errors all pointing back to one component. After confirming power and grounds were good, we pinpointed the BCM. Instead of a costly new unit and a day of programming, we used a cloned BCM. The customer sent us his old module, we transferred the data, and shipped the replacement back. He installed it in under 30 minutes in his own driveway, solving every single issue. It’s a perfect example of how a targeted repair can be both effective and efficient.
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:
- âś” Intermittent or non-functional power windows, locks, or mirrors.
- âś” Erratic behavior from interior or exterior lights (staying on or not turning on).
- âś” Horn honking unexpectedly or not working at all.
- âś” Security system faults or a ‘Service Theft Deterrent System’ message.
- âś” Wipers operating randomly or not responding to the switch.
- âś” Communication failure Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other ‘U’ codes.
- âś” Problems with key fob recognition or push-to-start functionality.
Your Straightforward BCM Installation Guide
Installing your cloned 2014 Sierra 1500 BCM is a simple process. Our service handles the complex programming, so all you need to do is swap the part.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most trucks like the Sierra and Silverado, the BCM is located under the driver’s side of the dashboard, near the steering column. On other models (like the Corvette or CTS), it may be in the LH dash area or on the firewall.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the module from its mounting bracket.
- Install the Replacement: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions controlled by the BCM—windows, locks, lights, wipers, etc.—to confirm the repair was successful.
- Post-Installation Checks: In some cases, additional steps may be needed. If your airbag light is on, an ‘Airbag System Sync’ may be required. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary for proper brake light and traction control operation. These procedures require a professional-grade scan tool.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we read the specific vehicle data—including VIN, key information, and optional settings—from your original BCM and write it directly onto the replacement module. This makes the new part a perfect digital match for your vehicle, avoiding the need for dealer programming.
Why do I have to send my original module?
Your original module contains the unique digital fingerprint for your truck. Sending it to us is the only way to extract this data to create a true plug-and-play replacement. This process ensures all systems communicate correctly after installation.
Is this a guaranteed fix for my 2014 Sierra 1500 BCM issues?
If your vehicle’s symptoms match those of a failing BCM and the module has been properly diagnosed as the fault, this service provides a reliable and complete solution. It restores factory functionality without extra programming hassles.
What if my airbag light is on after I install the new BCM?
This can happen occasionally. It means the new BCM and the Airbag Control Module (SDM) need to be electronically re-introduced. A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. We need your original module for the data transfer, but you can keep it afterward if you wish.
