Finally, A Real Fix for Your Truck’s Electrical Headaches
If you’re dealing with bizarre and frustrating electrical issues in your 2001 GM truck or SUV, you know how maddening it can be. One day the power windows work, the next they don’t. The security light is flashing, or the interior lights have a mind of their own. These aren’t just annoyances; they’re signs that your Body Control Module (BCM) is failing. This isn’t just a replacement part—it’s the definitive, pre-programmed solution to restore your vehicle’s reliability and get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty BCM can cause a cascade of confusing problems that are often misdiagnosed. If your truck is experiencing any of the following, this module is the solution you need:
- Erratic or non-working power windows, door locks, and mirrors.
- Interior lights staying on or not turning on at all.
- The security system preventing the vehicle from starting (blinking security light).
- Inconsistent or malfunctioning dashboard warning lights.
- Problems with the radio or climate control functions.
- Diagnostic Trouble Codes (DTCs) related to communication loss with various modules.
Instead of wrestling with a used module that requires expensive dealership programming, our Programmed 2001 GM Truck BCM 9375899 arrives at your door flashed with the latest GM software and coded specifically to your vehicle’s VIN.

Expert Insight: Why Pre-Programming is Non-Negotiable
On these early 2000s GM vehicles (the GMT800 platform), the BCM is the central hub for nearly all the electronic features you use every day. It’s not just a simple fuse box; it’s a computer that needs to speak the same language as your Engine Control Module (ECM) and instrument cluster. Simply swapping in a used BCM from a junkyard will almost always result in a no-start condition due to the PassLock security system. Our VIN programming service correctly configures the module, making the installation process as smooth as possible for a vehicle of this generation. We handle the complex computer work so you can focus on the straightforward physical installation.
Frequently Asked Questions
How do I provide my VIN number?
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 a critical part of the service.
What tools are needed for the post-installation procedures?
In some cases, a high-level diagnostic scan tool (like a Snap-on, Autel, or GM Tech 2) is required for the ‘Setup SDM Primary Key in BCM’ (airbag sync) or Brake Pedal Position Relearn. Many local repair shops can perform these quick procedures for a minimal fee if they are necessary for your vehicle.
Will this fix my specific electrical problem?
This Programmed 2001 GM Truck BCM 9375899 is the solution for the vast majority of issues listed in the symptoms section. While proper diagnosis is always recommended, a failing BCM is the most common culprit for these specific, widespread electrical gremlins on 2001 GM trucks and SUVs.
Is this a difficult part to replace myself?
The BCM is typically located under the driver’s side of the dashboard. For someone with basic mechanical skills, the physical replacement is straightforward and usually takes less than an hour. It involves removing a few dash panels and disconnecting electrical connectors. Our pre-programming service eliminates the most difficult part of the job.
What does the BCM actually control?
The Body Control Module acts as the central computer for your vehicle’s body electronics. This includes power windows, power locks, interior and exterior lighting, the alarm/security system, radio functions, and communication between various other electronic modules throughout the vehicle.
