Expert Insight from a 20-Year Technician
I’ve seen countless owners and even professional shops get stuck chasing electrical gremlins for days, replacing switches and relays only to find the problem persists. In these early 2000s GM vehicles, the BCM is often the root cause. The real challenge used to be the programming—it required specialized, dealer-level scan tools. This Programmed GM BCM 9371990 completely changes the game. It allows a skilled DIYer or any independent shop to perform a repair that was once a dealership-only job, saving hundreds of dollars and significant downtime. It’s the smartest way to fix it right the first time.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) is essential because it allows us to load the exact software and calibrations your specific vehicle requires. This includes settings for options like keyless entry, power seats, and drivetrain. This step makes the module a true plug-and-play part and is crucial for proper function.
Is this BCM difficult to install?
For someone with basic mechanical skills, the installation is straightforward. The BCM is typically located under the driver’s side dashboard. The process involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors from the old module to swap in the new one. No special programming tools are needed on your end.
What if my airbag light is on after installation?
In some cases, the new BCM may need to be synchronized with the airbag system’s Supplemental Deployment Module (SDM). If the airbag light appears, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync that a well-equipped independent shop can perform.
Will this fix my specific electrical problem?
This module is the solution for a vast majority of the electrical issues listed in the description. While we can’t diagnose your vehicle remotely, if you are experiencing multiple, unrelated body electronic failures, a faulty BCM is the most common culprit. This Programmed GM BCM 9371990 is the definitive component to solve those problems.
Do I need to send my old part back?
No. There is no core charge or requirement to return your original module. You can keep it or dispose of it at your convenience.
