Fix Your Silverado’s Electrical Faults for Good
If you’re dealing with bizarre electrical issues in your 2007-2011 Chevrolet Silverado 3500, a failing Body Control Module (BCM) is the likely culprit. As the central command for your truck’s body electronics, a faulty BCM can cause chaos—from flickering lights and dead power windows to a persistent airbag warning light. This isn’t just an annoyance; for a workhorse like the Silverado 3500, it’s downtime that costs you time and money. This module, part number 15901388, is the definitive solution, offered with our expert cloning service to get you back on the road without a trip to the dealership.
We transfer the critical data from your original BCM directly to this replacement unit. This means it arrives at your door ready for a true plug-and-play installation, pre-configured to your truck’s specific VIN and options. Forget about expensive diagnostic tools or dealer appointments for programming. This is the most efficient way to restore full functionality to your vehicle’s essential systems.
Case Study: The Ghost in the Machine
A customer brought in his ’09 Silverado 2500, a sister truck to the 3500, with a list of complaints that sounded like a poltergeist had taken up residence. The radio would turn on by itself, the driver’s side window wouldn’t roll down, and the airbag light was on with a B1001 code. He’d already replaced the battery and checked grounds. After a quick scan, I suspected the BCM. These modules are notorious for causing multiple, unrelated faults. We swapped in one of our cloned BCMs, and in less than 10 minutes, every single issue was resolved. It’s a classic case I’ve seen hundreds of times; a single module failure making a solid truck feel unreliable.
Is Your Silverado Showing These Symptoms?
- âś” Unresponsive or erratic power windows, door locks, or mirrors.
- âś” Interior or exterior lights that flicker, stay on, or don’t work at all.
- âś” HVAC system problems, like a blower motor that won’t turn on or stays stuck on high.
- âś” An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- âś” Security system malfunctions, leading to no-start or stalling conditions.
- âś” A dashboard that looks like a Christmas tree with multiple, unrelated warning lights.
A Straightforward Guide to BCM Installation
Replacing the BCM in your truck is a simple job that most owners can complete in their own driveway. Our cloning service eliminates the most difficult part—the programming.
- Safety First: Always disconnect the negative terminal from your truck’s battery before working on any electronic components.
- Locate the BCM: On these Silverado models, the Body Control Module is typically found 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 electrical connectors from the old BCM. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the new, cloned BCM into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the truck and test all the functions controlled by the BCM—lights, locks, windows, wipers, and HVAC—to confirm the repair was successful.
- Post-Installation Check: In some cases, if the airbag light was on, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ function to clear the light. A Brake Pedal Position relearn may also be required on certain models.

Frequently Asked Questions
How does the cloning service work?
You send us your original BCM. We extract the vehicle-specific programming and immobilizer data and flash it onto the replacement module. This makes the new part a perfect digital copy of your old one, ensuring it works seamlessly with your truck’s other systems without any additional programming.
Do I need to return my old BCM as a core?
We require your original module to perform the cloning service. However, there is no core charge, and we always ship your original module back to you along with the newly programmed replacement unit.
Will this fix my airbag light?
If the airbag light is caused by a faulty BCM (like with code B1001), this replacement will resolve the root cause. However, after installation, you may need a professional scan tool to run the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is this a difficult part to install myself?
Not at all. For someone with basic tools and a little confidence, it’s a very straightforward job that takes only a few minutes. The module is easily accessible under the dash, and our cloning service means you won’t have to worry about the complex programming side of the repair.
What is your warranty on this part?
We stand behind our parts and services. This Body Control Module comes with a one-year warranty, giving you peace of mind that you’re making a lasting repair.
