Restore Full Control Over Your Truck’s Electronics
If your 2013 Chevrolet Silverado 3500 is plagued by bizarre electrical issues, the Body Control Module (BCM) is the likely culprit. As the central command for your truck’s body electronics, a failing BCM can cause a cascade of frustrating problems, from non-responsive power windows and door locks to a malfunctioning HVAC system or a persistent airbag light. This isn’t just an annoyance; it’s a matter of safety and reliability. This replacement Body Control Module, part number 15926094, is the definitive solution, engineered to OEM specifications to restore flawless operation to your vehicle’s essential functions.
We make the repair process straightforward with our professional Cloning Service. Simply send us your original BCM, and we’ll transfer its unique data—including key information and vehicle-specific settings—to this replacement unit. The result is a true plug-and-play module that requires no expensive trip to the dealership for programming. It arrives ready for installation, integrating seamlessly with your Silverado’s existing systems.
Is Your Silverado Showing These Electrical Gremlins?
A faulty BCM can manifest in numerous ways. Over my 20 years in diagnostics, I’ve seen these modules cause some of the most confusing symptoms. If you’re experiencing any of the following, a new BCM is your most probable fix.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔ The security system acts up, causing no-start conditions or false alarms.
- ✔ An airbag warning light is illuminated on the dash, often with DTC B1001.
- ✔ Communication errors with other modules on the vehicle network (U-codes).
From the Diagnostic Bay: The Case of the Corroded Ground
A customer brought in a 2011 Sierra 2500 with a laundry list of intermittent electrical problems—the radio would cut out, the dome light would flicker, and sometimes the power locks wouldn’t work. They had already replaced the battery and alternator with no success. After hooking up my scanner, I saw a dozen communication codes. The BCM was losing power. Instead of just swapping the module, I checked its foundation. Tucked up under the dash, I found the main ground wire for the BCM had developed corrosion from a small windshield leak the owner didn’t even know about. We cleaned the ground point, secured the connection, and replaced the BCM that had been damaged by the erratic voltage. It’s a perfect example of why checking your connections is just as important as replacing the part itself.
A Straightforward Guide to BCM Installation
Replacing the 2013 Silverado 3500 BCM is a job most DIYers can handle in their own driveway in under 15 minutes. The module is typically located under the driver’s side dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your truck’s battery to prevent electrical shorts.
- Locate the Module: Find the BCM under the driver-side dash. It’s a plastic box with several large multi-pin electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- Install the New BCM: Mount the new module in place and securely reconnect all the electrical harnesses. You’ll hear a ‘click’ when they are properly seated.
- Power Up: Reconnect the negative battery terminal. Your truck’s electronics should now be fully functional.
- Post-Install Checks: If the airbag light remains on, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” function. Some models may also require a Brake Pedal Position Relearn.

Frequently Asked Questions
What is a BCM Cloning Service?
Cloning is a service where we transfer the essential vehicle-specific data from your original, faulty BCM to the replacement unit. This makes the new part plug-and-play, avoiding the need for expensive and time-consuming dealership programming.
Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a common cause of the B1001 code. However, after installing the new module, you may need to use a professional-grade scan tool to perform the “Setup SDM Primary Key in BCM” procedure to sync the airbag system and clear the light.
Do I have to send my old part back?
Yes, for our cloning service to work, you must send us your original BCM. We perform the data transfer and then ship both your original module and the newly programmed replacement back to you. There is no core charge.
Where is the BCM located on my 2013 Silverado 3500?
The Body Control Module on this generation of GM trucks is located under the driver’s side of the dashboard, typically to the left of the steering column. It is a black plastic box with multiple large electrical connectors.
Is this a reliable, long-term fix?
Absolutely. This module is built to meet or exceed original equipment standards for performance and durability. It comes with a one-year warranty, giving you peace of mind that you’re making a lasting repair.
