Restore Full Electrical Function to Your Buick Regal
If you’re battling bizarre electrical problems in your 2014-2017 Buick Regal—like power windows with a mind of their own, flickering interior lights, or unresponsive door locks—you’re likely dealing with a failing Body Control Module (BCM). As the central hub for your car’s body electronics, a faulty BCM can cause a cascade of frustrating issues. Dealerships often quote a small fortune for a new module and the mandatory programming. We offer a smarter, more affordable solution: a fully programmed BCM, ready for plug-and-play installation.
Our process is simple and designed to get you back on the road fast. After your purchase, we’ll coordinate with you to ship your original BCM to our facility. Our expert technicians will then extract the precise vehicle-specific data and transfer it to this replacement module. This cloning service ensures that the replacement BCM is a perfect match for your Regal’s unique configuration, eliminating the need for expensive and time-consuming dealer programming. We ship the ready-to-install module back to you, and you can restore your vehicle’s functionality with a simple swap.
A Technician’s Notebook
I remember a 2015 Regal that came into the shop with a complaint that was driving the owner crazy: the radio would randomly turn off, and the driver’s side window would sometimes refuse to go down. No check engine light, no obvious codes at first glance. After checking the basics (fuses, wiring), we dug into the BCM data stream. We noticed intermittent communication drops that lined up perfectly with the owner’s complaints. These ‘ghost’ issues are classic signs of an internally failing BCM. Instead of a costly new unit, we provided a cloned BCM. The customer saved hundreds, and the car’s electronics have been flawless ever since. It’s a textbook case of how a failing BCM can manifest in confusing ways.
Is Your Regal Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system acting up or preventing the car from starting.
- ✔ Inaccurate readings on the instrument cluster.
- ✔ Communication error codes (often U-codes) stored in the system when scanned.
- ✔ Remote keyless entry failing to work consistently.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2014-2017 Regal, the Body Control Module is typically located behind the driver’s side of the dashboard, often near the kick panel area.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Seat your newly programmed BCM into the mounting bracket and secure it. Reconnect all electrical connectors firmly until they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Test and Verify: Start the car and test all body functions: windows, locks, lights, wipers, and radio to ensure everything is working correctly. Note the post-installation procedures below.
Important Post-Installation Information
While our programming makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. If you notice an airbag warning light, a professional scan tool will be needed to perform the “Setup SDM Primary Key in BCM” procedure. Additionally, some models may require a Brake Pedal Position Sensor relearn to ensure proper brake light and traction control operation. These procedures are only necessary if specific warning lights or issues appear after installation.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your car that acts as the central command for all non-engine related electronics. This includes your power windows, door locks, interior and exterior lighting, security system, wipers, and more. When it fails, these systems can behave erratically.
Why do you need my original BCM?
We need your original module to perform a data cloning service. We extract the unique vehicle identification number (VIN), security information, and specific options data from your old BCM and program it onto the replacement. This makes the new module a perfect electronic match for your car, avoiding the need for dealer programming.
Is this a difficult part to install myself?
For most DIYers with basic tools, this is a straightforward installation. The BCM is typically accessible behind the driver’s side dash. The main steps are disconnecting the battery, unplugging the old module, and plugging in the new one. No special programming tools are required on your end.
What if the airbag light comes on after I install it?
In some cases, the airbag system (SDM) needs to be electronically re-synced with the new BCM. This is not a defect but a security handshake. The ‘Setup SDM Primary Key in BCM’ procedure can be performed by any professional shop with a compatible high-end scan tool to clear the light.
How long does the programming service take?
We pride ourselves on a fast turnaround. Once we receive your original BCM, our technicians typically complete the programming and ship your replacement module back out within 1-2 business days. We will provide you with tracking information as soon as it ships.
Is there a core charge or do I need to send my old part back?
There is no core charge for this item. We only need your original module for the initial data transfer. Once the service is complete, you can keep your original module.
