Restore Full Electrical Control to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your late 90s or early 2000s GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or strange warning lights on the dash are all classic signs of a failing Body Control Module (BCM). This central command unit is the brain behind your vehicle’s body electronics, and when it starts to fail, it can make driving a daily challenge. This replacement BCM, part number 19153625, is the definitive solution to restore your vehicle’s functionality and your peace of mind.
Unlike a generic part from a local store, this BCM is delivered to you fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest GM software updates before it ships, ensuring optimal compatibility and performance. This critical step eliminates the need for an expensive trip to the dealership for programming, saving you significant time and money. Simply provide your VIN after purchase, and we handle the complex part for you.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways, often intermittently at first. If you’re experiencing any of the following issues, a failing BCM is the most likely culprit:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security system or anti-theft light flashing, preventing the vehicle from starting.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Wipers operating incorrectly or not turning off.
- ✔ False warnings on the instrument cluster (e.g., “Door Ajar” light).
- ✔ Communication issues with other modules, leading to various diagnostic trouble codes.
The Superior Solution: A VIN-Programmed 1999-2000 Silverado BCM
Replacing the BCM on these vehicles isn’t just a matter of swapping boxes. The module must be correctly programmed to communicate with the other computers in your truck, like the Engine Control Module (ECM) and the Sensing and Diagnostic Module (SDM) for the airbag system. Our service streamlines this entire process. By programming the 1999-2000 Silverado BCM before shipping, we ensure that it integrates seamlessly with your vehicle’s existing systems. This is a direct-fit, plug-in solution designed to get you back on the road quickly and reliably.
Installation and Post-Install Procedures
This BCM is typically located behind the dashboard, either in the center or on the lower left-hand (driver’s) side. While the physical installation is straightforward for a DIYer with basic tools, a couple of electronic relearn procedures may be necessary after the new module is connected. Please be aware of the following:
- Airbag System Sync: If your airbag warning light illuminates after installation, it means the new BCM needs to be synchronized with the airbag’s SDM. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a safety-critical step to ensure the airbag system is fully operational.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed. This ensures your brake lights function correctly and that systems like ABS and traction control receive the proper input from the pedal sensor.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process.
This module is a direct replacement for a wide range of GM trucks and vans. It is compatible with part numbers 19153625, 8191536250, 16257125, 191583625, 8093668010, 8162571250, 8191536250, and 09366801. Please verify the part number on your original module to ensure a perfect match.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and various other comfort and convenience features.
Is this BCM truly plug-and-play?
Because we program it to your VIN, it is as close to plug-and-play as possible, eliminating the need for dealer programming. However, as noted, some vehicles may require a post-installation ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ using a professional scan tool to clear warning lights and ensure full system integration.
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 part to function correctly in your vehicle.
What happens if the airbag light is on after I install it?
This is a common occurrence. It means the security keys between the new BCM and the airbag module (SDM) need to be synchronized. A repair shop with a high-level diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
