Is Your GM Truck Plagued by Electrical Gremlins?
Are you dealing with flickering interior lights, power windows that have a mind of their own, or a security system that randomly goes off? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, managing everything from your power locks and dome lights to the instrument cluster and anti-theft system. When it starts to fail, it can cause a cascade of bizarre and frustrating electrical issues that can be difficult to diagnose.
Don’t let a faulty module sideline your reliable truck. This is a direct-replacement, VIN-programmed Body Control Module for a wide range of 1998-2000 GM trucks and SUVs, including the Chevrolet Silverado and GMC Sierra. We take the guesswork and hassle out of the repair. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software updates specific to your truck. It arrives at your door ready for a straightforward installation, saving you a costly trip to the dealership and the expense of programming fees.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, and mirrors.
- ✔ Erratic or inoperative interior and exterior lighting (dome lights, headlights, taillights).
- ✔ Instrument cluster gauges behaving strangely or not working at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ A persistent “Service Vehicle Soon” or security light on the dash.
- ✔ Unexplained battery drain when the vehicle is turned off.
Solving Problems with a Pre-Programmed 1999-2000 Silverado BCM
The biggest hurdle in replacing a BCM has always been the need for specialized, dealer-level programming. Without it, the new module won’t recognize your vehicle’s specific options or communicate with other computers like the ECU and airbag module. Our solution eliminates this step entirely. By programming the module to your VIN before shipping, we ensure it’s a true plug-and-play replacement. This 1999-2000 Silverado BCM is meticulously inspected and prepared to restore your truck’s functionality right out of the box.
Important Post-Installation Procedures
While this module is designed for a simple installation, some vehicles may require additional steps to ensure all systems are communicating correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade diagnostic tool to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM acts as the central computer for your vehicle’s non-engine related electronic features. It controls power windows, locks, interior/exterior lights, the alarm system, wipers, and often communicates with the instrument cluster.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your truck’s specific features and options. This ensures it works correctly right out of the box without requiring a trip to the dealer for programming.
Is this BCM difficult to install?
For most DIY mechanics, the physical installation is straightforward. The BCM is typically located under the driver’s side dashboard. The main challenge is usually the programming, which we handle for you. Some vehicles may require a simple relearn procedure after installation.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
What if my airbag light comes on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag module. A technician with a high-end scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
