Tired of Unpredictable Electrical Problems in Your GM Truck?
If your 2015 Silverado 3500 is experiencing a frustrating array of electrical gremlins—from flickering lights and malfunctioning power windows to random warning chimes or even a no-start condition—a failing Body Control Module (BCM) is the likely culprit. As the central nervous system for your truck’s comfort and convenience features, a faulty BCM can make driving a nightmare. Dealerships often charge a small fortune for a new module plus the mandatory, time-consuming programming. We offer a smarter, more cost-effective solution.
This is a fully tested, replacement BCM compatible with part number 13594769 and others. The real value is in our professional cloning service. You simply ship us your original BCM, and we transfer 100% of its critical data—including your vehicle’s specific VIN, mileage, and optional features—to this replacement unit. The result is a true plug-and-play module that eliminates the need for expensive dealership programming. Get your truck back to full function without the hassle.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Sierra 2500—a close cousin to the Silverado—with a truly bizarre set of symptoms. The radio would turn on by itself, the driver’s side window wouldn’t go down, and the horn would randomly honk when turning left. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a flood of U-codes, specifically U0140 (Lost Communication With Body Control Module). This pointed directly to an internal BCM failure. Instead of a costly new unit from the dealer, we used our cloning service. We transferred his data to a replacement module, he installed it in under 30 minutes, and every single issue was resolved. It’s a textbook example of how a failing 2015 Silverado 3500 BCM can cause chaos, and how cloning provides a perfect, targeted fix.
Is Your Truck Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system light is flashing, preventing the engine from starting.
- ✔ The horn, radio, or windshield wipers are activating without input.
- ✔ Multiple, unrelated warning lights on the dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or B1001 stored in the system.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your truck’s battery before starting any electrical work.
- ✔ Locate the BCM: On most 2015 Silverado/Sierra models, 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 multiple wiring harnesses connected to the module. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Mount your newly programmed BCM in the same location and securely reconnect all wiring harnesses. You’ll hear a ‘click’ when they are properly seated.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, locks, windows, radio, etc.
- ✔ Post-Installation Checks: Start the vehicle. If an airbag light appears, an “Airbag System Sync” may be required by a professional. Similarly, a “Brake Pedal Position Relearn” might be necessary. See details below.
Important Notes on Post-Installation Procedures
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a quick handshake with the new BCM. This is normal. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated 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 recalibration may be needed to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to return your old BCM to us after the service. The price you pay is final, with no hidden core fees.

Frequently Asked Questions
How does the cloning service work?
After you purchase, we will provide you with instructions to ship your original BCM to us. Our technicians will then extract the unique data from your module and flash it onto the replacement unit. We then ship the programmed module back to you, ready for installation.
What if my original BCM is completely dead or water damaged?
In many cases, even if the BCM is non-functional, we can still recover the necessary data from the memory chip. Please contact us before ordering if your module has severe physical or water damage so we can assess the situation.
Is this really plug-and-play?
Yes, for over 95% of installations. Because we clone your original data, the vehicle recognizes the new module as its own, eliminating the need for programming. In rare cases, minor relearn procedures for systems like the airbags or brake pedal sensor may be needed, as described above.
How long does the entire process take?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. The total time will depend on shipping times to and from our facility. We will provide you with a return tracking number once it ships.
Do I need to send in my keys?
No. Since we are cloning the data directly from your original BCM, all of your existing keys will work seamlessly with the new module upon installation. No key relearn procedure is required.
