Restore Your Truck’s Electrical System with a Plug-and-Play BCM
If you’re dealing with bizarre electrical gremlins in your 2014 Sierra 1500—like flickering lights, malfunctioning power windows, a dead battery from a parasitic draw, or a security light that prevents the truck from starting—a failing Body Control Module (BCM) is the likely culprit. As the central nervous system for your vehicle’s electronics, when the BCM goes down, it can cause a cascade of frustrating and seemingly unrelated problems. The dealership solution involves a new, expensive module and several hours of programming fees. We offer a smarter, more affordable path forward.
This is a replacement Body Control Module, compatible with part number 13593214 and others, that is delivered to you ready for installation. Our expert mail-in cloning service eliminates the need for dealership intervention. Simply send us your original BCM, and we will transfer all the critical vehicle-specific data—including VIN, mileage, and key programming—to this replacement unit. When you receive it back, it’s a true plug-and-play solution, restoring your truck’s functionality without the high cost and hassle. Get back on the road with confidence, knowing your truck’s electronics are working as they should.
A Technician’s Notebook: The Phantom Battery Drain
A customer brought in a 2014 Silverado with the classic complaint: “My battery is dead every morning.” He’d already replaced the battery and alternator. After hooking up an ammeter, I saw a 2-amp draw long after the truck was shut off. Instead of pulling fuses for an hour, I went straight to the BCM with a thermal imager. It was glowing faintly—a dead giveaway it wasn’t going into ‘sleep’ mode. The internal processor was stuck, keeping other modules awake all night. A cloned 2014 Sierra 1500 BCM (the same part) solved the problem instantly. These phantom draws are one of the trickiest symptoms of BCM failure, and this service is the most direct fix.
Is Your Sierra Showing These BCM Failure Signs?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the solution you need. In my shop, I’ve seen these issues hundreds of times, often accompanied by communication codes like U0140, U0155, or B1001.
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or failing to turn on.
- ✔ The anti-theft or security system light is illuminated, causing a no-start condition.
- ✔ Inexplicable battery drain that kills your battery overnight (parasitic draw).
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
Your Straightforward BCM Installation Guide
Installing your newly programmed BCM is a manageable task for a DIY enthusiast. The goal is a direct swap. Remember to take your time and handle the electronic components with care.
- Safety First: Always disconnect the negative terminal from your truck’s battery and wait at least 10-15 minutes to allow all systems to power down completely.
- Locate the BCM: On most 2014-2015 GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, often to the left of the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug all electrical connectors from the original BCM. They have locking tabs that need to be depressed. Once all connectors are free, unbolt or unclip the module from its mounting bracket.
- Install the Replacement: Mount the new, programmed BCM in the exact same location and orientation. Firmly re-seat all electrical connectors, ensuring each one clicks securely into place. A loose connection is a common cause of post-installation issues.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, locks, windows, wipers, etc.
- Post-Installation Procedures: In some cases, additional steps may be needed. If your airbag light is on, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. A Brake Pedal Position Relearn might also be necessary for proper brake light and traction control operation.

Frequently Asked Questions
How does the mail-in cloning service work?
It’s simple. After you place your order, we will contact you with shipping instructions. You send us your original BCM. We then extract the vehicle-specific data and flash it onto the replacement module. We ship the programmed module back to you, ready for installation.
Will I need to program this BCM at the dealership?
No. Our cloning service transfers all necessary programming, including the VIN and security information. This makes the module plug-and-play, saving you from expensive dealer programming fees.
Do I need to send my keys with the module?
No, you do not need to send us your keys. All the necessary immobilizer and key data is stored within the BCM itself, and we transfer it directly during the cloning process. Your existing keys will work seamlessly.
Is there a core charge for this part?
No, there is no core charge. We only require your original module for the data transfer. You can keep your original, non-working module after the service is complete.
What if my airbag light comes on after installation?
This can occasionally happen. It requires a specific procedure called ‘Setup SDM Primary Key in BCM’ to be performed with a professional-grade scan tool to sync the airbag system with the new BCM. This is a quick procedure for any competent repair shop.
