Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Is your Silverado or Sierra acting possessed? Flickering lights, intermittent power windows, a security system that randomly engages, or worse—a no-start condition that leaves you stranded. As a technician with over two decades of experience, I’ve seen these frustrating electrical gremlins hundreds of time. The culprit is often a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics. A faulty BCM can turn a reliable truck into a source of constant headaches. This isn’t just an inconvenience; it can be a safety issue when lights or locks fail unexpectedly.
We offer a straightforward, reliable fix. This is a replacement Body Control Module, part number 13594692, that comes perfectly programmed to your vehicle’s specifications. How? Through our simple cloning service. After your purchase, we’ll provide instructions for you to ship your original BCM to our facility. Our expert technicians will then transfer all the critical data—including key programming and vehicle-specific options—to this replacement unit. We then ship it back to you, ready for a simple, plug-and-play installation. This process eliminates the need for an expensive trip to the dealership and the use of specialized diagnostic tools for programming.
From the Diagnostic Bay: The Case of the Ghostly Silverado
A customer brought in a 2015 Silverado 2500 with a list of bizarre issues. The radio would turn off, the dome light would flicker while driving, and occasionally, the truck wouldn’t start, just a click. He’d already replaced the battery and checked the alternator. After hooking up my scan tool, I found a slew of communication error codes (U-codes) pointing to a network problem. Instead of chasing wires for hours, experience told me to look at the network’s hub: the BCM. A quick check of the BCM’s power and grounds confirmed they were good. The module itself was failing internally, causing the entire communication network to crash intermittently. A cloned BCM like this one had him back on the road the next day, with all electrical functions restored to normal. It’s the most efficient fix for these exact symptoms.
Is Your Vehicle Exhibiting These BCM Failure Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The anti-theft or security system light is on, preventing the engine from starting.
- ✔ The horn honking unexpectedly or not working when pressed.
- ✔ Multiple, seemingly unrelated warning lights on the dashboard.
- ✔ Diagnostic trouble codes (DTCs) stored in the system, such as U0140, U0155, or other communication failures.
- ✔ A complete no-start condition where the starter doesn’t engage.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- ✔ Locate the BCM: On most GM trucks like the 2015 Silverado 2500, the BCM is located under the steering column, on the driver’s side of the dashboard. On other models, it may be on the firewall or behind a kick panel.
- ✔ Remove the Old Module: Carefully disconnect all the electrical connectors. They have locking tabs that must be depressed to be removed. Then, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Seat your pre-programmed replacement BCM onto the mounting bracket and secure it. Reconnect all electrical connectors firmly, ensuring they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, radio, etc.—to confirm proper operation.
Post-Installation Checks
Our cloning service makes this a nearly plug-and-play process. However, in some GM vehicles, a couple of quick relearn procedures may be needed after installation. These are not signs of a faulty part but are standard vehicle security and safety handshakes.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure brake lights and traction control function correctly. This is often a simple procedure that can be done with a capable scan tool.
Disclaimer: We always recommend consulting a factory service manual or a qualified technician for procedures specific to your vehicle’s exact year and model. No core charge is required; you can keep your original module.

Frequently Asked Questions
What is the process after I buy this?
After you place your order, we will contact you with simple instructions and a shipping address to send us your original BCM. Once we receive it, we clone the data to the replacement module and ship it back to you, usually within one business day.
Do I need to get this programmed by a dealer?
No. The main benefit of our service is that the module arrives pre-programmed with your vehicle’s data. This allows for a plug-and-play installation without needing any dealer tools or software.
Is this a guaranteed fix for my vehicle’s electrical problems?
This module will fix any issues directly caused by a faulty BCM. The symptoms we’ve listed are the most common indicators. If you’re unsure, it’s always best to have a professional technician diagnose the vehicle to confirm the BCM is the root cause.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM is failing, we can still extract the necessary data for cloning. If your module has severe physical damage (fire, water), please contact us before ordering to discuss options.
Do I need to send back my old part after installation?
No, there is no core charge for this part. You only need to send us your original BCM for the initial cloning service. You can keep it afterward.
