End the Electrical Gremlins in Your 2014 Sierra 1500
Are you chasing bizarre electrical issues in your truck? Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or even a frustrating no-start condition? As a technician with over two decades of experience, I’ve seen these exact symptoms hundreds of times. The culprit is almost always a failing Body Control Module (BCM)—the central nervous system of your vehicle’s electronics. This isn’t just an inconvenience; it’s a breakdown of your truck’s core functions. We have the definitive, hassle-free solution.
This listing is for a replacement BCM, part number 13594692, that comes ready for installation through our professional cloning service. You simply send us your original BCM, and we transfer its unique programming and vehicle-specific data to this replacement unit. This process ensures all your truck’s options and security information are perfectly mirrored, eliminating the need for expensive and time-consuming dealership programming. Once we’re done, we ship the ready-to-install module right back to you. It’s the most reliable way to restore your truck’s functionality.
Is Your Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs attention. I’ve often seen communication-related Diagnostic Trouble Codes (DTCs) like U0100, U0140, or B1325 stored when a BCM is on its way out.
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ The security system light stays on, or the alarm randomly triggers.
- ✔ The engine won’t crank, even with a good battery (security system fault).
- ✔ Multiple, unrelated warning lights appearing on the instrument cluster.
- ✔ Radio or infotainment system malfunctions.
- ✔ Key fobs are not being recognized by the vehicle.
A Technician’s Notebook
I remember a 2014 Sierra 1500 that came into the shop with a complaint that stumped two other mechanics. The owner said every few days, the horn would blare, the wipers would turn on, and the truck wouldn’t start. By the time it was towed, it would start right up. There were no consistent codes. After checking grounds and wiring, I suspected the BCM. On these GM trucks, the BCM is the traffic cop for dozens of systems. A slight internal failure, often from heat cycles or voltage spikes, can cause it to send out phantom commands. We cloned his original module to a new unit, and the ‘haunted’ truck was cured. This is why a simple data transfer is often the most effective fix.
A Straightforward Guide to Installation
Installing your newly programmed 2014 Sierra 1500 BCM is a manageable job for a DIYer with basic tools. The BCM is typically located under the steering column on the driver’s side.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On most Sierra/Silverado models, you’ll need to remove the lower dash panel beneath the steering wheel to access the module.
- Disconnect the Connectors: Carefully unplug all electrical connectors from the old BCM. They have locking tabs, so be gentle and use a small flathead screwdriver if needed to depress the tabs.
- Remove the Old Module: Unbolt or unclip the original BCM from its mounting bracket.
- Install the New BCM: Mount your new, programmed BCM in the same location and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Final Steps: Reinstall the dash panel and reconnect the negative battery terminal. Start the vehicle to verify that everything is working correctly.
Important Post-Installation Information
While our cloning service makes this a near plug-and-play repair, some vehicle systems may require a quick sync-up after the new module is installed. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the airbag system and the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure the brake lights and traction control system function as intended.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. We then use specialized equipment to extract the vehicle-specific data and transfer it to the replacement BCM. We ship the programmed module back to you, ready for installation. Tracking will be provided.
Do I need to take my truck to the dealer after installing this?
No. Our cloning service transfers all the necessary programming, including the VIN and security information, so you can avoid a trip to the dealership for programming.
Is there a core charge for this part?
No, there is no core charge. We only need your original module to perform the data transfer. Once the service is complete, you can keep your original part.
What happens if my original BCM is completely dead or not communicating?
In many cases, even if a BCM is failing, we can still extract the necessary data. If your module is completely unresponsive (e.g., due to water or fire damage), please contact us before ordering to discuss options.
How long does the programming service take?
We typically program and ship your replacement BCM within 24-48 hours of receiving your original module, getting you back on the road as quickly as possible.
