Are you chasing down electrical gremlins in your GM truck or SUV? One minute the power windows work, the next they don’t. Maybe the radio cuts out randomly, or a security light on the dash just won’t go away. As a technician with over two decades of experience under the hood of these vehicles, I’ve seen this exact scenario hundreds of times. The culprit is almost always a failing Body Control Module (BCM), the electronic nerve center for your vehicle’s comfort and convenience features.
This isn’t just another part; it’s a direct solution. We are offering a replacement Body Control Module, compatible with part numbers 09371990, 19208539, and 9385236. The best part? It arrives at your door pre-programmed with the latest GM software, specifically flashed to your vehicle’s VIN. This eliminates the most expensive and time-consuming step: a trip to the dealership for programming. You get a reliable fix that restores your vehicle’s functions without the typical hassle.
Case Study: A Tricky Diagnosis
I remember a 2000 Silverado that came into my shop with the strangest collection of symptoms. The owner said his interior lights would flicker, the horn would honk when he used the turn signal, and the power locks had a mind of their own. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a dozen communication error codes (U-codes) pointing to the BCM. Instead of installing a blank module and charging him for programming, we used one of our VIN-programmed units. Within an hour, the truck was fixed. Every function worked perfectly. This is the power of a pre-programmed module—it turns a complex electronic nightmare into a straightforward repair.
Is Your Truck Showing These Symptoms?
A failing BCM can cause a wide range of confusing issues. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior.
- ✔ The radio or climate controls turning on or off by themselves.
- ✔ A persistent “Security” or anti-theft light on the dashboard.
- ✔ The horn sounding unexpectedly or not working at all.
- ✔ Communication error codes stored in the system (Common DTCs: U0140, B1000, B1001).
A Straightforward Guide to Your BCM Installation
Replacing the 2000 Tahoe Body Control Module is a manageable job for a DIYer. Located under the driver’s side of the dashboard, it’s accessible with basic hand tools. Follow these steps for a smooth installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
- Locate the BCM: On most of these GM trucks and SUVs, the BCM is a black plastic box with multiple large electrical connectors, mounted to the left of the steering column.
- Remove Connectors: Carefully unplug all wiring harness connectors from the old module. They have release tabs that need to be pressed or lifted. Do not force them.
- Unbolt the Old Module: Remove the mounting bolts or nuts holding the original BCM in place and take it out.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and secure it with the original hardware.
- Reconnect Everything: Plug all the wiring harnesses back into the new module until they click securely. Reconnect the negative battery terminal.
Post-Installation Checks & Procedures
Because this module is pre-programmed, your vehicle should start and run. However, depending on your specific model, a couple of simple synchronization procedures might be needed:
- ✔ Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- ✔ Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure brake lights and traction control function correctly. This also typically requires a capable scan tool.
Disclaimer: While this 2000 Tahoe Body Control Module is designed for easy installation, procedures can vary. We always recommend consulting a factory service manual for your specific vehicle.

Frequently Asked Questions
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your module until we receive this information.
Is this a plug-and-play part?
Yes, for the most part. Because we program it to your VIN, it will control the vehicle’s core functions upon installation. However, as noted, some vehicles may require an additional Airbag Sync or Brake Relearn procedure with a scan tool.
Do I need to return my old BCM?
No. We do not charge a core fee for this module. You can keep your original part.
Will this fix my specific problem?
This module corrects faults originating within the BCM itself. The symptoms listed above are the most common indicators of a failing BCM. If your vehicle exhibits these issues, this part is the most probable solution.
What if the part number on my module is slightly different?
This module is a direct replacement for service numbers 19208539, 9371990, and 9385236. As long as your original module carries one of these numbers and your vehicle is on the compatibility list, it will work correctly.
