End the Electrical Chaos: A Reliable Fix for Your GM Vehicle
Are you chasing electrical gremlins in your 2014 Silverado 1500? Flickering lights, malfunctioning power windows, a security system that acts up, or even a frustrating no-start condition can all point to one central culprit: a failing Body Control Module (BCM). As the nerve center for your truck’s comfort and convenience features, a faulty BCM can make driving a nightmare. Instead of facing a costly trip to the dealership for a new module and expensive programming, we offer a straightforward, reliable solution.
This is a replacement Body Control Module, compatible with part number 13594768 and others, that comes pre-programmed with the data from your vehicle’s original unit. Our expert cloning service transfers your truck’s specific configuration, including the VIN and options, directly onto this replacement module. The result is a true plug-and-play component that restores full functionality without requiring any additional programming or dealer intervention. This saves you significant time, money, and the headache of vehicle downtime.
Case Study: A Tricky Diagnosis
A customer brought in a 2014 Sierra 1500, a cousin to the Silverado, with a bizarre set of symptoms. The radio would turn on by itself, the driver’s side window wouldn’t go down, and the instrument cluster would randomly go dark while driving. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a flood of U-codes (U0140, U0155) indicating a loss of communication with the BCM. Instead of a complex rewiring job, we confirmed the BCM itself was failing internally. By cloning his original module to one of our replacements, we had him back on the road in an afternoon for a fraction of the dealership’s quote. The plug-and-play nature of the fix meant no extra labor for programming.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security system or keyless entry works intermittently or not at all.
- ✔ The instrument panel gauges behave strangely or go blank.
- ✔ The radio or climate controls are unresponsive.
- ✔ Your vehicle won’t start, and you’ve ruled out the battery and starter.
- ✔ Diagnostic trouble codes (DTCs) related to body systems or communication errors (e.g., B-series or U-series codes) are present.
A Straightforward Guide to Installation
Installing your programmed BCM is a simple process that most DIYers can handle. Here’s a general guide for a 2014 Silverado 1500:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the BCM: On most of these trucks and SUVs, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Power: Re-attach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—windows, locks, lights, radio, etc. Note that some post-install procedures may be necessary (see below).
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a relearn procedure to sync with the new BCM. This is normal. Key procedures include:
- Airbag System Sync: If the airbag warning light is on 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.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be required on certain models.
Disclaimer: Procedures can vary. Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will clone the data to the replacement module and ship it back to you, usually within one business day.
Is this a plug-and-play part?
Yes. Because we clone the data from your original module, this part is fully programmed for your specific vehicle. It will not require a trip to the dealer for programming, though some minor relearn procedures may be needed post-installation as noted.
Do I need to return my old BCM?
No, there is no core charge for this part. After we clone the data, we will ship your original module back to you along with the replacement. You can keep it.
What part numbers does this replace?
This module is a direct replacement for several part numbers, including 13594692, 13594768, 13593214, 13580690, 13591519, and 13594769.
What if my airbag light comes on after installation?
This can happen occasionally. It simply means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
