Restore Your Vehicle’s Brain, Hassle-Free
Are you battling bizarre electrical issues in your vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or even a car that refuses to start can all point to a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause immense frustration. This isn’t just a part; it’s the solution to getting your vehicle back to the reliable, fully-functional machine it was meant to be.

Frequently Asked Questions
What exactly does the Body Control Module do?
The Body Control Module, or BCM, acts as the central computer for your vehicle’s non-engine related functions. It controls features like power windows, power locks, the alarm system, interior and exterior lighting, wipers, and other comfort and convenience electronics. When it fails, these systems can become erratic or stop working altogether.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the module to function in your specific vehicle.
Is this a difficult part to install?
For someone with moderate mechanical experience, the physical installation is typically straightforward. The BCM is usually located under the dashboard on the driver’s or passenger’s side. The main challenge is typically the programming, which we handle for you. This makes the installation process significantly easier than a standard replacement.
Will I need to perform any procedures after installation?
In some cases, yes. Depending on your vehicle’s specific configuration, you may need a professional scan tool to perform a ‘Brake Pedal Position Relearn’ or an ‘Airbag System Sync’ if the airbag light comes on. These are standard post-replacement procedures for many modern vehicles.
How can I be sure this programmed 15819552 BCM fits my vehicle?
Please check the extensive list of compatible part numbers and vehicle models provided in the description. The most accurate way to ensure a match is to cross-reference the part number from your original BCM. If it’s on our list, this module is the correct replacement for you.
