Is Your GM Truck Plagued by Baffling Electrical Problems?
If you’re dealing with power windows that have a mind of their own, door locks that won’t cooperate, or interior lights that flicker for no reason, you’re likely facing a failing Body Control Module (BCM). These issues can be more than just an annoyance; they can compromise your vehicle’s security and your peace of mind. Instead of spending a fortune at the dealership, get your trusted truck back to its reliable self with our pre-programmed BCM, the straightforward solution to these frustrating electrical gremlins.

An Expert’s Note on Diagnostics
“I’ve seen countless owners of these classic GM trucks chase electrical issues for weeks. They replace window motors, door lock actuators, and even instrument clusters, only to find the problem persists. That’s because the BCM is the central command for all these components. A failing BCM sends bad signals, making good parts act faulty. Before you spend another dollar on guesswork, address the root cause. A pre-programmed BCM is often the single most effective repair to restore the vehicle’s electrical integrity and your sanity.”

Important Post-Installation Information
While our goal is a simple plug-and-play experience, some vehicles may require one of the following procedures to finalize the installation. This is normal for these systems. A professional scan tool may be required.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag module.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be necessary to ensure correct brake light and traction control operation.
This programmed 1999-2000 Silverado 1500 BCM is the key to getting your truck back in reliable, working order. Don’t let electrical problems dictate when your truck is usable. Take control and fix it right.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, door locks, interior and exterior lighting, security systems, and wipers.
How does the VIN programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to load the correct GM-certified software and vehicle-specific settings onto the BCM before we ship it to you, ensuring it communicates properly with your truck.
Is this part difficult to install?
For most DIYers with basic tools, the physical installation is straightforward. The BCM is typically located under the driver’s side dashboard. The main challenge with BCM replacement is usually the programming, which we handle for you. Some post-install procedures may require a scan tool, as noted above.
What happens if my airbag light is on after installation?
This is a common security measure in GM vehicles. It means the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). A repair shop with a capable diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to send you my old BCM?
No. This purchase has no core charge. You can keep, recycle, or dispose of your original module at your convenience, saving you the time and expense of shipping it back.
Will this fix my intermittent 4×4 engagement issues?
While the BCM can contribute to a wide range of electrical issues, problems with the 4×4 system are often related to the Transfer Case Control Module (TCCM), the dash switch, or the front axle actuator. However, if you are also experiencing other BCM-related symptoms listed above, replacing the BCM is a logical step in your diagnosis.
