Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you battling bizarre electrical issues in your GM vehicle? Flickering dashboard lights, power windows with a mind of their own, or a security system that randomly prevents your car from starting are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it can affect your vehicle’s safety and reliability. We offer a dependable and straightforward solution: a professionally programmed BCM that gets you back on the road without the exorbitant costs and scheduling hassles of a dealership visit.
This is a replacement BCM, compatible with part number 13593214, that is delivered to you ready for installation. Our expert service involves cloning the essential data—including VIN, mileage, and security information—from your original module to this replacement unit. This means no additional programming or expensive scan tools are required on your end. Simply install the module, and your vehicle’s functions are restored. This is the ideal fix for both savvy DIYers looking to save on repair bills and professional mechanics seeking a reliable source for pre-programmed modules.
From the Diagnostic Bay: The Silverado’s Electrical Gremlins
A 2015 Silverado 2500 came into my shop with a laundry list of complaints from the owner. The radio would turn off, the dome lights would flicker while driving, and occasionally, the power locks wouldn’t respond. He’d been to two other shops that couldn’t find the issue because no hard fault codes were stored. On a hunch, I connected my scope to the communication lines at the BCM. I noticed significant voltage drops and hash on the line whenever the driver’s side window was operated. The BCM’s internal circuitry was failing under load, corrupting the data network. A new, programmed 2014-2017 SS Caprice BCM (which shares compatibility) solved every single issue. These modules are the unsung heroes of vehicle electronics, and when they fail, the symptoms can be incredibly misleading.
Common Signs Your GM Vehicle’s BCM is Failing
If you’re experiencing any of the following, a faulty BCM is the likely culprit. A failing module can also trigger various communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or U0164.
- ✔ Erratic or non-functional interior and exterior lighting.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ Intermittent no-start condition where the engine cranks but won’t fire up.
A Straightforward Guide to Your BCM Installation
Our cloning service makes the physical replacement simple. Once you receive your programmed module from us, follow these general steps. The BCM is typically located under the driver’s side dashboard, near the steering column or left kick panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate and Access: Remove any necessary trim panels to gain clear access to the original Body Control Module.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the exact same location and orientation. Securely reconnect all electrical connectors.
- Power Up: Reconnect the negative battery terminal.
- Test All Functions: Before reassembling your dash, turn the key to the ‘On’ position and test all related functions: lights, locks, windows, horn, and key fobs. Start the vehicle to ensure it operates correctly.
Important Post-Installation Notes
In some cases, minor relearn procedures may be necessary after installation. This is normal and ensures all related vehicle systems are properly synchronized with the new BCM.
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only required if the light appears.
- Brake Pedal Position Relearn: Certain models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
- Disclaimer: Procedures can vary. Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
How exactly does your cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Our technicians will then extract the critical vehicle-specific data and transfer it to the replacement module. We then ship the plug-and-play replacement back to you, typically within 1-2 business days of receiving your original part.
What if my original BCM is water-damaged or won’t communicate?
In many cases, even with significant damage, we can still recover the necessary data. Please contact us before ordering if your module has severe water or fire damage so we can assess the likelihood of a successful data transfer.
Will I need to do any programming myself?
No. The module you receive from us is fully programmed with your vehicle’s information. The goal of our service is to eliminate the need for any dealer-level programming tools, making the installation as simple as possible.
Is there a core charge for this part?
No, there is no core charge. We need your original module to perform the cloning service, but you are not required to leave it with us. We will ship your original BCM back along with the newly programmed replacement.
How do I know if this part number will fit my vehicle?
This BCM, primarily identified by part number 13594692, replaces several other part numbers including 13593214, 13594768, and more. Please check the detailed fitment list on this page or match one of the compatible part numbers to your original module to ensure a perfect fit.
