Tired of Your Regal’s Electrical Gremlins? Here’s the Solution.
If you’re dealing with flickering lights, malfunctioning power windows, a stubborn security system, or a car that refuses to start, you’re likely facing 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 unpredictable problems. Instead of paying for expensive diagnostics and dealership programming, our pre-programmed Regal Body Control Module offers a direct, reliable, and cost-effective fix.
Our unique service simplifies the entire repair process. You send us your original BCM, and we transfer all its critical data—including VIN, mileage, and key information—to this replacement unit. The module you receive back is a true plug-and-play solution, eliminating the need for a trip to the dealer and the use of specialized scan tools for programming. It’s the most straightforward way to restore your vehicle’s full functionality.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Buick Regal with a laundry list of bizarre symptoms. The radio would turn on by itself, the driver’s side window wouldn’t go down, and the anti-theft light would flash intermittently, sometimes preventing the car from starting. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I found multiple communication loss codes (U-codes) pointing to the BCM. Instead of a costly new module and hours of programming, we used this exact cloning service. The customer shipped their old module, we sent back the programmed replacement, and the installation took them less than 30 minutes. All the strange electrical issues were gone instantly. It’s a testament to how effective this solution is for complex problems.
Common Signs of a Failing BCM
A failing Regal Body Control Module can manifest in various ways. If you’re experiencing any of the following, this part is likely the solution you need:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors behaving unpredictably.
- ✔ The vehicle’s security system engaging randomly or causing no-start conditions.
- ✔ Horn, wipers, or radio activating without input.
- ✔ Dashboard warning lights (like the airbag or brake light) staying on.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other U-series codes.
A Straightforward Guide to Installation
Our cloning service makes the physical replacement simple. After you receive your programmed module from us, follow these general steps. The BCM in the 2014-2017 Regal is typically located behind the left side of the dashboard.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Access the Module: Carefully remove the necessary trim panels on the driver’s side dash to expose the BCM.
- Disconnect and Remove: Unplug the electrical connectors from your old BCM. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all the electrical connectors, ensuring they click into place.
- Final Steps: Re-install the trim panels and reconnect the negative battery terminal. Start the vehicle to confirm that the issues are resolved.
Important Post-Installation Information
While our service handles the core programming, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional diagnostic tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure your brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
