Are you chasing down frustrating electrical gremlins in your 2014-2017 Chevrolet Caprice? One moment the power windows work, the next they don’t. Maybe your dash lights are flickering like a disco ball, or worse, the car won’t start at all. In my 20+ years of experience, these phantom issues often point directly to a failing Body Control Module (BCM). It’s the central nervous system for your vehicle’s accessories, and when it goes bad, it can cause chaos.
Forget expensive dealership visits and the headache of programming a new module from scratch. This is a hassle-free solution: a replacement BCM, part number 13594768, that arrives at your door fully programmed and ready for installation. We achieve this through a professional cloning service. Simply purchase this item, and we’ll contact you with instructions to ship your original BCM to our facility. Our technicians will extract the unique data from your module and flash it onto this replacement unit. The result? A true plug-and-play fix that restores full functionality to your vehicle without any additional programming fees.
Is Your Vehicle Showing These Symptoms?
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ Erratic instrument cluster behavior or flickering dashboard lights.
- ✔ The security or anti-theft system preventing the engine from starting.
- ✔ False warnings for lights being out or doors being ajar.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ Inconsistent operation of the radio, climate control, or other comfort features.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Silverado with a complaint that was driving him crazy: the horn would randomly go off, and the interior lights would stay on, draining the battery overnight. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a dozen intermittent communication codes pointing nowhere specific. This is a classic sign of a BCM failure. The internal processors start to break down, sending corrupt data across the vehicle’s network. We performed our cloning service on a replacement BCM, and the truck was back to normal the same day. It’s rarely the accessory itself; it’s the computer that controls it.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: In most compatible vehicles, including the 2014-2017 Caprice, the BCM is located under the steering column or behind the driver’s side dash. Consult your vehicle’s service manual for the exact position.
- ✔ 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 BCM: Mount your pre-programmed replacement module in the same location. Securely plug in all the electrical connectors, ensuring each one clicks 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 was successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your 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 new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure the brake lights and stability control systems function correctly.
Disclaimer: These procedures are not always required. Always refer to a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with a shipping address. You send us your original BCM. We then transfer its programming and security data to the replacement module and ship it back to you, typically within 1-2 business days of receiving your part.
Do I need to take my car to the dealer after installation?
No. Because we clone your original module’s data, this part is fully programmed for your specific vehicle. This process eliminates the need for any dealership programming, saving you time and money.
Is there a core charge for my old BCM?
No, there is no core charge. You are free to keep your original module after you send it to us for the data transfer service.
Will this fix my specific problem?
This part corrects issues caused by a faulty BCM. If your vehicle exhibits symptoms like erratic lights, non-functional accessories, or security system faults, a failing BCM is the most likely cause. Proper diagnosis is always recommended.
What if my original BCM is completely dead or missing?
Our cloning service requires a readable original module. If your BCM is missing, water damaged, or non-communicative, please contact us before ordering to discuss other potential programming options.
