Restore Your Vehicle’s Electronics with a Hassle-Free BCM Solution

Are you tired of chasing electrical gremlins in your GM vehicle? Intermittent power windows, door locks with a mind of their own, or a security light that prevents your car from starting are all classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s comfort and convenience features, a faulty BCM can make your daily drive incredibly frustrating. This isn’t just an inconvenience; it can affect safety systems and leave you stranded. This GM Body Control Module 15819552 is your direct-fit, reliable solution.

We take the guesswork and high costs out of the equation with our professional cloning service. Forget about expensive dealership visits for programming. You simply send us your original BCM, and we transfer all the critical, vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. When you receive it back, it’s a true plug-and-play installation. This process ensures seamless integration with your vehicle’s existing electronic systems.

Common Signs of a Failing BCM

If your vehicle is experiencing these issues, a failing BCM is the likely culprit. In my 20 years of experience, these are the most common symptoms I’ve seen tied to this exact module.

• ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
• ✔ The security or anti-theft light stays on, preventing the engine from starting.
• ✔ Dashboard warning lights (like Airbag or ABS) illuminate for no reason.
• ✔ The horn sounds unexpectedly or doesn’t work at all.
• ✔ Communication-related Diagnostic Trouble Codes (DTCs), especially U-codes, are stored in the system.
• ✔ Wipers or radio operate intermittently or not at all.

A Straightforward Guide to Installation

Our cloning service makes the physical swap simple. While the BCM location varies, the process is generally the same. Always consult a service manual for your specific vehicle’s procedure.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
2. Locate the BCM: On most of these GM models, the BCM is located under the driver’s side of the dashboard, near the steering column, or behind a panel in the center console/dash area.
3. Remove Your Original BCM: Carefully disconnect the electrical connectors. They have locking tabs that must be pressed to release. Remove any bolts or clips holding the module in place and send it to us for the cloning service.
4. Install the New BCM: Once you receive the cloned module from us, simply plug it in and secure it in place. The connectors are keyed and will only fit one way.
5. Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair is complete.

Important Post-Installation Information

In some cases, additional steps may be required after installation. This is normal and depends on your vehicle’s specific configuration.

• Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
• Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.

Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
