Tired of Unpredictable Electrical Problems in Your Cadillac?
If your 2014 Cadillac XTS is starting to act haunted—with power windows that have a mind of their own, dashboard lights flickering randomly, or a security system that prevents the car from starting—you’re likely dealing with a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated issues. Driving a luxury vehicle should be a pleasure, not a guessing game of which feature will fail next. This isn’t just an inconvenience; it can impact vehicle security and safety systems.
We offer a straightforward, reliable solution: a replacement BCM, part number 13594692, that arrives at your door fully programmed for your vehicle. We achieve this through a professional cloning service. Simply send us your original BCM, and our expert technicians will transfer all the critical vehicle-specific data to this replacement unit. The result? A module that is 100% plug-and-play, eliminating the need for expensive dealership programming or towing fees. This is the definitive fix for your 2014 XTS BCM issues.
Case Study: A Tricky Diagnosis
A customer brought in a 2014 Cadillac CTS with a bizarre complaint: the radio would turn on by itself, and the driver’s side power window would only work intermittently. They had already replaced the window switch and checked the fuses. In the shop, we noticed that when scanning for codes, we’d get intermittent U0140 (Lost Communication With Body Control Module) errors. Instead of just throwing parts at it, we monitored the BCM data stream. We saw erratic voltage readings corresponding to the exact functions the customer described. It was a classic internal BCM failure. By cloning his original module to one of our tested units, we restored full functionality without a trip to the dealer. This is the kind of precise, effective repair we provide.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the most likely culprit:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system activates incorrectly, causing a no-start condition.
- ✔ Dashboard warning lights (like the airbag or service vehicle light) illuminate for no reason.
- ✔ The key fob stops working or only works sporadically.
- ✔ Communication error codes, such as U0140, are present when scanned.
- ✔ Wipers, horn, or other accessories operate on their own or not at all.
A Straightforward Guide to BCM Replacement
Installing your pre-programmed BCM is a manageable task for a DIY enthusiast. For the 2014 Cadillac XTS, the BCM is typically located behind the left front hinge pillar trim panel. Always confirm the location for your specific model.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Original BCM: Access the BCM by carefully removing any trim panels or covers. On the XTS, this is usually on the driver’s side near the A-pillar/hinge area.
- Disconnect and Remove: Carefully unplug the electrical connectors from the module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Final Steps: Re-install any trim panels you removed and reconnect the negative battery terminal. Start the vehicle to confirm that the primary issues are resolved.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal. If you encounter these specific issues, a relearn procedure may be needed:
- Airbag System Sync: If the 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 new BCM for safety.
- Brake Pedal Position Relearn: On some models, the brake pedal position sensor may need to be recalibrated to ensure brake lights and stability control systems function correctly.
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
How does the 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 unique data from your module and flash it onto the replacement unit. We then ship the plug-and-play replacement back to you.
Do I need to send my original BCM?
Yes. This service requires your original module to transfer the vehicle-specific programming. This process ensures 100% compatibility and avoids any need for additional programming after installation.
Is there a core charge?
No, there is no core charge for this service. You can keep your original module after we have completed the data transfer.
How long does the process take?
We typically program and ship the replacement module within 1-2 business days of receiving your original BCM. You will receive tracking information as soon as it ships.
What if the airbag light comes on after I install it?
This can happen occasionally. It simply means the airbag system needs to be re-synced with the new BCM. A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
