Restore Your Truck’s Electrical System with a Hassle-Free Solution
Are you battling bizarre electrical issues in your 2014 GMC Sierra Denali 1500? Flickering lights, a battery that dies overnight, or power windows and locks with a mind of their own are classic signs of a failing Body Control Module (BCM). The BCM is the central command for your truck’s body electronics, and when it fails, it can cause a cascade of frustrating and hard-to-diagnose problems. Dealerships often charge a fortune for a new module plus hours of labor for programming. We offer a smarter, more affordable path back to reliability.
This is a complete, ready-to-install BCM that is professionally programmed using the data from your vehicle’s original module. Our mail-in cloning service makes this complex repair incredibly simple. You send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key programming—to this replacement unit. The result? A module that is truly plug-and-play, eliminating the need for expensive diagnostic tools or a trip to the dealer. This service covers part number 13593214 and is a direct replacement for several other part numbers.
Case Study: The Ghost in the Machine
I once had a 2014 Sierra in the bay that was driving its owner crazy. The radio would turn on by itself, the dome lights would flicker while driving, and occasionally, it wouldn’t start. The battery and alternator checked out perfectly. After chasing wires for hours, we hooked up the scope to the communication lines connected to the BCM. We saw erratic data packets and voltage drops that weren’t setting a specific code. It was the BCM slowly failing internally. By cloning his original module, we had the truck fixed in a day, saving him from a potential $1200+ dealership bill and the headache of leaving his truck there for days.
Is Your Sierra Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system acting up or preventing the engine from starting (anti-theft light on).
- ✔ A parasitic battery drain that kills your battery overnight.
- ✔ False warning messages on the instrument cluster (e.g., ‘Service 4WD’).
- ✔ Communication error codes with other modules, such as U0140 (Lost Communication With Body Control Module).
A Straightforward Guide to Swapping Your BCM
Replacing the BCM is a manageable job for a DIYer with basic tools. The key is our cloning service, which handles the complex software side. Here’s a general guide for the physical swap in a 2014 Sierra Denali 1500:
- Safety First: Always disconnect the negative terminal from your truck’s battery and wait a few minutes before starting any electrical work.
- Locate the BCM: On most of these trucks, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect the Connectors: Carefully unplug all the electrical connectors from the old BCM. They have locking tabs that need to be pressed to release. Do not force them.
- Remove the Old Module: The BCM is typically held in place by a few bolts or clips. Remove the fasteners and take out the original module. This is the unit you’ll ship to us.
- Install the New Module: Once you receive your programmed BCM from us, simply mount it in place and reconnect all the electrical connectors. Ensure they click securely into place.
- Reconnect and Test: Reinstall any trim panels you removed, reconnect the battery, and start the vehicle. Test all functions like lights, locks, windows, and radio to confirm the repair.
Important Post-Installation Steps
While our cloning makes this a near plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the BCM and is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure brake lights and stability control function correctly. This also requires a capable diagnostic tool.
- No Core Charge: You are not required to return your original module after the service is complete. There is no core charge.

Frequently Asked Questions
How does the mail-in cloning service work?
It’s simple! After your purchase, we’ll provide instructions for shipping your original BCM to us. Once we receive it, we extract the vehicle-specific data and program it into the replacement module. We then ship the ready-to-install module back to you, typically within 1-2 business days.
Do I need to go to the dealer for programming after installation?
No. Our cloning service completely eliminates the need for any additional programming at a dealership or repair shop, saving you significant time and money.
Is this BCM truly plug-and-play?
Yes, for over 99% of installations. Because we clone your original data, the vehicle recognizes the new module as its own. In rare cases, a simple relearn procedure like for the airbag or brake pedal sensor may be needed, as detailed above.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM isn’t functioning in the vehicle, we can still recover the necessary data directly from the circuit board. Please contact us with details about your module’s condition if you have concerns.
Does this fit other part numbers?
Yes, this module, part number 13594692, is a direct, compatible replacement for several part numbers, including 13594768, 13593214, 13580690, 13591519, and 13594769.
