Restore Full Electrical Function to Your Vehicle
Is your Buick Regal, LaCrosse, or Malibu plagued by strange and unpredictable electrical issues? Flickering lights, malfunctioning power windows, a dead instrument cluster, or security system faults are often not isolated problems but symptoms of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, coordinating everything from your interior lights and door locks to the anti-theft system. When it fails, it can create a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module, part number 13590851, is the definitive solution to restore your vehicle’s electronic stability and performance.
From the Diagnostic Bay
We had a 2015 Buick Regal come into the shop that was driving the owner crazy. The radio would randomly turn off, the dome light would stay on, and occasionally, the car wouldn’t start, displaying a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication error codes pointing to the BCM. Instead of a costly and time-consuming replacement at the dealership, we used our cloning service. We transferred the data from his old, faulty module to a quality replacement. After a quick installation, all the bizarre electrical gremlins were gone. It’s a common scenario, and this programming service is the most efficient fix.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from the instrument cluster, including dead gauges or flickering warning lights.
- ✔ Headlights, taillights, or interior lights not working correctly (staying on or not turning on).
- ✔ Malfunctioning keyless entry and remote start systems.
- ✔ The security or anti-theft system activating incorrectly, preventing the car from starting.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ False warnings on the driver information center (DIC).
Why Choose Our Programmed Regal Body Control Module?
Dealerships will often charge a premium for a new BCM, followed by several hours of labor for installation and programming. Our service streamlines this entire process. We take your vehicle’s unique, essential data—like key programming, security information, and specific options—from your original BCM and transfer it directly to this replacement unit. The result is a module that is 100% plug-and-play. There is no need for expensive dealer-specific tools or additional programming fees. This is the most straightforward and cost-effective way to get your car back to perfect working order.

Installation and Post-Install Notes
For the 2014-2017 Buick Regal, the BCM is typically located behind the left-hand (driver’s side) of the dashboard. While installation is a matter of disconnecting the battery and swapping the modules, some post-installation procedures may be necessary depending on your specific vehicle.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only needed if the light appears.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be required to ensure proper brake light operation and traction control functionality.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a qualified automotive technician for specific guidance.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your car that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the anti-theft system. It’s the central command for your vehicle’s body electronics.
How does the mail-in programming service work?
After you place your order, you ship your original BCM to us. We extract the vehicle-specific data from it and flash that data onto the replacement module. We then ship the programmed module back to you, ready for installation.
Is this part truly plug-and-play?
Yes. Because we clone the data from your original module, the replacement BCM will be recognized by your vehicle as the original. This eliminates the need for any additional programming or key relearning procedures from a dealership.
What happens if my airbag light comes on after I install it?
In some cases, the BCM needs to be electronically ‘shaken hands’ with the airbag module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure, which is a quick process for any qualified shop.
Where is the BCM located on my 2014-2017 Buick Regal?
On the 2014-2017 Regal, the Body Control Module is typically found on the driver’s side, behind the dashboard near the kick panel area.
Do I need to send my keys or any other parts?
No, we only need your original Body Control Module. All the necessary key and security information is stored within the BCM itself, which we will transfer to the replacement unit.
