End the Electrical Gremlins in Your GM Truck or Car
Is your 2014 Sierra 1500 acting possessed? Flickering lights, malfunctioning power windows, a security system that randomly engages, or worse, an intermittent no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM goes bad, it creates a cascade of frustrating and unpredictable problems. Instead of spending a fortune at the dealership for a new module and expensive programming, we offer a simple, reliable, and cost-effective solution.
This is a replacement BCM, part number 13594692, that comes ready for installation through our professional cloning service. The process is straightforward: you purchase this module, send us your vehicle’s original BCM, and we transfer all the critical vehicle-specific data to the replacement unit. This ensures seamless integration with your truck’s existing systems, including the VIN, mileage, and key programming. We then ship the ready-to-install module back to you, eliminating the need for any dealer-level programming on your end. It’s the most direct path to getting your truck back to normal.
Case Study: A Tricky Diagnosis
A customer brought in a 2014 Silverado with a complaint that was driving him crazy. The radio would turn off, the dash lights would flicker, and occasionally the truck wouldn’t start—but there were no consistent trouble codes. After checking the battery and grounds, which is always the first step, we hooked up a scope to the communication network. We saw significant data corruption whenever the symptoms appeared. This pointed directly to a failing module. By swapping in one of our pre-programmed BCMs, we had the truck running perfectly in under an hour, saving the customer hundreds compared to the dealership’s quote and days of diagnostic headaches.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need for your 2014 Sierra 1500 BCM issues:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or alarm engaging without reason, possibly causing a no-start.
- ✔ Inaccurate gauge readings or gauges that stop working altogether.
- ✔ Communication error codes, such as U0100, U0140, or other ‘U’ codes, indicating a loss of communication with other modules.
- ✔ The radio or infotainment system randomly shutting off or behaving erratically.
Your Straightforward BCM Swap Guide
Once you receive your programmed module from us, installation is a direct swap. For a 2014 Sierra 1500, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: Remove the lower dash panel beneath the steering wheel to gain access to the module. It’s a black box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all wiring harnesses from the original 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 same location. Securely reconnect all the wiring harnesses to their correct ports.
- Power Up: Reconnect the negative battery terminal. Your vehicle’s core functions should now be restored.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure to fully sync all systems. These do not require a trip to the dealer but may need a capable scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the airbag system. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for procedures specific to your vehicle.

Frequently Asked Questions
How does the mail-in programming service work?
It’s simple. After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer its data to the replacement module and ship the plug-and-play unit back to you, typically within one business day.
Will I need to do any programming or visit a dealer?
No. Our cloning service handles all the necessary programming. The module you receive from us will be ready to install and function in your vehicle without any additional dealer intervention.
Where is the BCM located on my 2014 Sierra 1500?
On the 2014 GMC Sierra 1500, the Body Control Module is located under the driver’s side dashboard, typically to the left of the steering column. You will need to remove the lower dash trim panel for access.
What if my airbag light turns on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and clear the light.
Is there a core charge for this part?
No, there is no core charge. We use your original module for data cloning only. You are welcome to keep your old part after the service is complete.
