Restore Your Vehicle’s Brain and End Electrical Frustration
Are you dealing with a vehicle that seems to have a mind of its own? Flickering lights, power windows that won’t cooperate, a security system that acts up, or a key fob that’s suddenly ignored? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your car’s comfort and convenience features, and when it malfunctions, it can cause a cascade of baffling electronic issues. For owners of a 2014 Cadillac CTS and a wide range of other GM vehicles, finding a reliable fix without a costly trip to the dealership can feel impossible. That’s where we come in.
This is a replacement Body Control Module, compatible with part number 13593214 and others, offered with our expert programming service. We eliminate the biggest headache of BCM replacement: the programming. Instead of you paying for expensive dealer-only tools and labor, we handle it all. Simply purchase this service, and we’ll contact you with instructions to ship your original BCM to our facility. Our technicians will professionally clone all the critical data—including VIN, mileage, and key programming—onto this replacement unit. We then ship the plug-and-play module back to you, ready for installation. It’s the most straightforward and cost-effective way to get your vehicle back to 100%.
A Technician’s Notebook: The Silverado with a Ghost
A 2015 Silverado 1500 came into the shop with the strangest symptoms. The owner said his radio would turn on by itself, sometimes in the middle of the night, draining the battery. His power door locks worked intermittently, and the dome light would flicker. He’d already replaced the battery twice. We ran diagnostics and found a slew of communication error codes (U-codes) pointing to the BCM. Water intrusion is a common killer for these modules, especially in trucks where a leaking windshield seal can drip directly onto the BCM under the dash. After confirming the failure, we performed a cloning service just like this one. The customer was able to install the replacement himself in under an hour, and the electrical ghost was gone for good. It’s a textbook example of how a failing BCM can mimic a dozen other problems.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, locks, or mirrors operate erratically or not at all.
- ✔ Interior or exterior lights flicker, stay on, or fail to turn on.
- ✔ The anti-theft system prevents the car from starting or triggers randomly.
- ✔ Key fobs are no longer recognized by the vehicle.
- ✔ The instrument cluster displays warning lights or incorrect information.
- ✔ Communication DTCs are present, such as U0140, U0155, or other related codes.
- ✔ Wipers or the horn activate without input.
Your Straightforward BCM Swap Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2014 CTS, the BCM is typically located in the left-hand side of the dash. For other models, it’s often under the steering column or on the firewall. Consult a service manual for your specific vehicle if unsure.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. Most have a locking tab that needs to be depressed or slid. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Mount your pre-programmed BCM in the same location and securely reconnect all the electrical connectors. Ensure they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal and tighten it securely.
- ✔ Test Functionality: Start the vehicle and test all the body functions—lights, locks, windows, wipers, etc.—to confirm the repair was successful.
Post-Installation Notes
In some cases, additional synchronization procedures may be required after installation:
- Airbag System Sync: If the airbag warning light is illuminated, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and stability control function.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will email you instructions and a shipping address. You mail your original BCM to us. We then extract its unique data and transfer it to the replacement module. We ship the new, plug-and-play module back to you, typically within 1-2 business days of receiving yours.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, and our cloning process transfers this data so your existing keys will work perfectly.
Is this a guaranteed fix for my car’s problems?
This service corrects issues directly caused by a faulty BCM. While the symptoms we list are extremely common for BCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before ordering.
What if I install it and the airbag light comes on?
This is a known possibility on some GM vehicles. It simply means the BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is there a core charge?
No, there is no core charge. You are not required to return your original module to us after the service, but we do need it initially for the data cloning process.
