Tired of Your Truck’s Electrical Gremlins? Take Control Back.
If your 2015 Silverado 3500 is acting possessed—with flickering lights, a dead instrument cluster, power windows with a mind of their own, or a security light that prevents it from starting—you’re not alone. These frustrating and unpredictable issues often point directly to a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics. When it fails, it creates chaos, turning your reliable workhorse into a source of constant headaches. Dealerships will quote you a fortune for a new module plus mandatory programming fees, leaving your truck sidelined for days. We offer a better, smarter, and faster solution.
This is a fully tested, reliable replacement BCM compatible with part number 13594692. The best part? We handle the programming for you. Through our expert mail-in cloning service, we transfer the exact data from your original BCM to this replacement unit. When you receive it back, it’s a true plug-and-play installation. You get to bypass the dealership, skip the expensive programming appointments, and restore your truck’s functionality with confidence. It’s the definitive fix for a complex problem, made simple.
Is Your GM Vehicle Showing These Symptoms?
- âś” Unpredictable power window or door lock operation.
- âś” Interior or exterior lights flickering, staying on, or not working at all.
- âś” The horn or alarm sounding randomly.
- âś” Instrument panel gauges behaving erratically or going completely dark.
- âś” A persistent anti-theft or security light, often causing a no-start condition.
- âś” Communication error codes, such as U0140, U0155, or other U-series codes, stored in the system.
- âś” False warnings appearing on the driver information center (DIC).
A Technician’s Notebook: The Case of the Haunted Sierra
A customer brought in a 2015 Sierra 2500, a near-twin to the Silverado, with a list of issues that sounded like something out of a ghost story. The radio would switch stations on its own, the dome light would fade in and out while driving, and twice the alarm went off in his garage overnight. He’d been to two other shops that couldn’t find the problem because it was so intermittent. After connecting my scan tool, I saw a dozen communication codes pointing to the BCM. Instead of a costly new module and a trip to the dealer, we used our cloning service. We had his original BCM overnighted, cloned it to a replacement unit, and sent it back. He installed it in under 30 minutes. The electrical ghosts were gone for good, and he saved hundreds of dollars.
How Our Simple Mail-In Programming Service Works
Our goal is to make this process as seamless as possible. After you place your order, we will contact you with clear, step-by-step instructions for shipping your original BCM to our facility. Please ensure your contact information is accurate during checkout. Once we receive your module, our technicians will perform a full data transfer to the replacement BCM. We then ship the plug-and-play replacement back to you, typically within 24-48 hours, and provide you with tracking information. You get a solution that’s programmed specifically for your vehicle’s VIN and options, without ever leaving your home or shop.
Your Straightforward BCM Installation Guide
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- âś” Locate the BCM: On most GM trucks and SUVs like the Silverado and Sierra, the BCM is located under the driver’s side of the dashboard, often near the steering column or against the firewall.
- âś” Remove Trim Panels: You may need to remove a lower dash panel or knee bolster to gain access. These are typically held by a few screws or clips.
- âś” 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.
- âś” Install the New BCM: Mount the new, programmed BCM in the same location and reconnect all electrical connectors securely. Ensure they click into place.
- âś” Final Steps: Reinstall any trim panels you removed and reconnect the negative battery terminal. Start the vehicle to confirm that the issues are resolved.
Important Post-Installation Information
While our programming makes this a plug-and-play part, some GM vehicles may require a simple relearn procedure to fully sync with the new module. This is normal and can often be done with a high-end scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called “Setup SDM Primary Key in BCM” is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure flawless operation of the brake lights and stability control systems.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we extract the critical vehicle-specific data—like the VIN, mileage, and settings for your options—from your original BCM and write it directly onto the replacement module. This makes the new part electronically identical to the old one, eliminating the need for further programming.
Is this really plug-and-play?
Yes. Because we’ve programmed it with your vehicle’s data, it will integrate seamlessly with the other modules in your car upon installation. In rare cases, a minor relearn procedure may be needed as noted above, but the core programming is complete.
Why do I need to send my original BCM to you?
Your original BCM holds the unique key and configuration data for your specific vehicle. Transferring this data is the only way to ensure a true plug-and-play installation and avoid a costly and complicated programming session at a dealership.
Do I have to pay a core charge?
No. There is absolutely no core charge for this service. You can keep your original module after you send it to us for the data cloning.
What if my original BCM is completely dead and won’t communicate?
In many cases, even if the BCM has failed operationally, the memory chip containing the essential data is still readable. We use specialized equipment to attempt data recovery. Please contact us if your module is severely damaged (e.g., by fire or water) to discuss options.
