An Expert’s Insight on GMT800 BCMs
As a technician with over two decades of experience, I’ve seen countless GMT800 platform trucks—the Silverado, Sierra, Tahoe, and Suburbans of this era. Their BCMs are workhorses, but after 20+ years, they’re prone to failure. Often, this is due to failing solder joints from thousands of heat cycles or internal corrosion from minor moisture intrusion around the cowl or windshield. The symptoms can seem random at first, leading owners down a rabbit hole of replacing switches and fuses. The truth is, a fresh, properly programmed BCM like this one is often the root solution, bringing the truck’s entire electrical accessory system back to life in one go. This isn’t just a part; it’s a permanent fix for a known weak point.

Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it.
Is this BCM difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. The BCM is typically located under the driver’s side of the dashboard. However, please be aware that post-installation procedures, like an airbag system sync or brake pedal position relearn, may be required and necessitate a professional-grade scan tool.
What happens if the airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be synchronized with the airbag’s Supplemental Deployment Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a compatible diagnostic tool to resolve this.
Will this fix my exact problem?
This Programmed 2000 GM Truck BCM 9371990 is a direct solution for failures within the module itself, which cause the symptoms listed above. While it solves the vast majority of these issues, you should always ensure your vehicle’s wiring and related components (like switches and motors) are in good condition. Proper diagnosis is key.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part that has been programmed with the most current software for your vehicle, ensuring reliable performance.
