If you’re wrestling with baffling electrical problems in your 2014-2017 Chevrolet Caprice or other compatible GM vehicle, you’ve likely met the frustrating reality of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen it all: lights flashing for no reason, power windows with a mind of their own, and security systems that randomly prevent the car from starting. These aren’t random quirks; they’re classic symptoms of a BCM breakdown. The BCM is the central command center for your vehicle’s body electronics, and when it falters, it creates chaos.
Forget expensive dealership visits that involve new modules, costly programming fees, and long waits. We offer a streamlined, reliable solution. This listing is for a replacement BCM, part number 13594692, that comes perfectly programmed with your vehicle’s original data. Our professional cloning service makes this a true plug-and-play repair. Simply send us your original BCM, and we’ll transfer all the critical information—including VIN, mileage, and key data—to this replacement unit. We ship it back to you, ready for immediate installation, with no further programming required.
What to Look For: Telltale Signs of BCM Failure
A failing BCM can be tricky to diagnose because its symptoms often mimic other issues. Based on my experience in the bay, here are the most common indicators that your BCM is the culprit. You might also see communication-related Diagnostic Trouble Codes (DTCs) like U0140, U0155, or other U-codes stored in various modules.
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors behaving unpredictably or not working at all.
- ✔ The vehicle’s security system or anti-theft light activating incorrectly, possibly causing a no-start condition.
- ✔ Horn honking unexpectedly or failing to work when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Radio or infotainment system issues, such as shutting off or losing settings.
From the Diagnostic Bay: The Case of the Caprice with a Mind of Its Own
A few months back, a 2015 Caprice PPV was towed to our shop. The owner, a local officer, was at his wit’s end. The patrol car’s interior lights would flicker constantly, the radio would cut out, and twice the anti-theft system had left him stranded. Other shops had replaced the battery and checked the alternator, but the electrical gremlins persisted. After hooking up the scan tool, I noticed a flood of communication errors across multiple systems, all pointing back to one component: the BCM. Instead of a costly new module and a full reprogramming session, we performed a BCM clone. Once the cloned module was installed, every single issue vanished. It’s a perfect example of how a single failing component can create system-wide chaos, and why our cloning service for the 2014-2017 Caprice BCM is such an effective repair.
Your Straightforward Installation Guide
Installing your pre-programmed BCM is a manageable task for a DIY enthusiast or a quick job for any professional mechanic. The exact location can vary, but it’s typically found within the cabin.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On most listed models, including the Caprice, the BCM is located under the driver’s side of the dashboard, often near the steering column or left-hand kick panel. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from your original BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the Replacement: Mount the new, cloned BCM in the same position and securely reconnect all electrical connectors. Ensure they click into place.
- Power Up: Reconnect the negative battery terminal. Your vehicle is now ready to go with all its original settings intact.
Post-Installation Checks
Our cloning service makes this a plug-and-play process, but on rare occasions, certain systems may require a quick sync. Please note the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure perfect operation of the brake lights and traction control system.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any procedure.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we’ll contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the unique data and flash it onto the replacement module. We then ship the programmed module back to you, ready for installation.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, the core data on the memory chip is still readable. We have advanced tools to recover data from most non-communicating modules. Please contact us if you have concerns about your module’s condition.
Do I need a dealership or special tools to program this BCM?
No. The entire point of our service is to eliminate the need for extra programming. The BCM you receive will be pre-programmed with your car’s data, making it a simple plug-and-play installation.
Is there a core charge or do I need to return my old BCM?
There is no core charge. We only need your original module temporarily to perform the cloning service. You can keep your original module after the service is complete.
Will this fix my specific problem?
This BCM will fix issues directly caused by a faulty Body Control Module. If you’re experiencing symptoms like erratic lights, power accessory failure, or security system faults, a failing BCM is the most likely cause.
