Is Your Vehicle Plagued by Bizarre Electrical Problems?
If you’re dealing with a frustrating mix of electrical issues—like power windows that won’t cooperate, door locks with a mind of their own, flickering interior lights, or a security system that randomly acts up—a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can create a cascade of confusing and unpredictable problems. This isn’t just an annoyance; it’s a matter of convenience and security. We have the reliable, straightforward solution you need.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways, often leaving you chasing symptoms instead of the root cause. If you’re experiencing any of the following, this module is the definitive fix:
- Intermittent or non-functional power windows, door locks, and mirrors.
- Interior or exterior lights staying on or not turning on at all.
- Erratic alarm or security system behavior (e.g., horn honking randomly).
- Key fob failing to lock or unlock the doors.
- Instrument cluster warning lights appearing without cause.
- No-start conditions where the starter fails to engage.
This Programmed 15819552 Body Control Module is engineered to resolve these issues permanently. We take the guesswork out of the repair by pre-programming the unit to your vehicle’s specific VIN, ensuring it’s ready for installation the moment it arrives.

Expert Insight: The ‘Brain’ of Your Car’s Comfort
As a technician with over 20 years of experience, I’ve seen countless drivers get frustrated by what seems like a dozen different electrical problems at once. They replace switches and check fuses, but the issues persist. That’s because the BCM acts as the central hub for all these components. Think of it as the brain for everything you interact with inside the cabin. When it malfunctions, the signals get crossed, leading to chaos. Installing a properly Programmed 15819552 Body Control Module doesn’t just fix one problem—it restores order to the entire system, giving you back a vehicle you can trust.
Post-Installation Information
While this module is designed for a simple installation, some vehicles may require additional steps to sync with other onboard systems. The most common procedures are an Airbag System Sync (if the airbag light is on) or a Brake Pedal Position Relearn. These procedures typically require a professional-grade scan tool. Please consult your vehicle’s service manual or a qualified technician for specific guidance.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will use this to program the module with the exact software and settings for your specific vehicle before we ship it.
Is this a difficult part to install myself?
For someone with moderate mechanical experience, the physical installation is straightforward. The BCM is typically located under the dash. The most critical part of the process is ensuring the module is correctly programmed, which we handle for you. Some vehicles may require additional relearn procedures after installation.
Will this fix my specific electrical problem?
This module is the direct solution for a wide range of body-related electrical failures. If you are experiencing multiple issues with components like power locks, windows, interior lights, and the security system, a faulty BCM is the most common cause. This Programmed 15819552 Body Control Module is designed to correct those system-wide failures.
What does ‘No Core Charge’ mean?
A core charge is a deposit that other companies charge you until you send back your old part. We make it simple: there is no core charge. You can keep your old module without any extra cost or hassle.
What happens if the airbag light comes on after installation?
This is a known possibility on some GM models. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
