Is Your GM Truck or SUV Experiencing Strange Electrical Problems?
If your 2000-2001 GM vehicle is acting possessed—with flickering lights, malfunctioning power windows and locks, a dead battery overnight, or a security light that prevents it from starting—the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, coordinating everything from the interior lights and power accessories to the anti-theft system. When it fails, it can create a cascade of frustrating and seemingly unrelated issues that can be difficult to diagnose.
The Simple, Reliable Solution for Your Vehicle
Instead of wrestling with a used module from a junkyard or paying steep dealership prices for a new one that still requires expensive programming, our pre-programmed BCM is your direct-fit, hassle-free solution. We take a genuine GM module and flash it with the latest official software updates specifically for your vehicle’s Vehicle Identification Number (VIN). This ensures perfect compatibility and restores your truck or SUV’s electronic functions to factory specifications. This is the definitive repair for a faulty 2000 GM Body Control Module.
From the Diagnostic Bay
We had a 2000 Silverado 1500 in the shop that was draining a brand-new battery in less than two days. The owner had already replaced the alternator and battery twice. After checking for parasitic draws, we noticed the BCM wasn’t properly putting all the vehicle’s circuits to sleep after the key was off. The interior courtesy light circuit had a tiny, almost imperceptible draw that was killing the battery over time. A new, correctly programmed BCM solved the problem instantly. It’s a classic example of how a faulty BCM can cause symptoms that seem completely unrelated to its function.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operate intermittently or not at all.
- ✔ The security or anti-theft light stays on, causing a no-start condition.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The radio or instrument cluster behaves erratically.
- ✔ Unexplained parasitic battery drain leads to a dead battery.
- ✔ Remote keyless entry stops working.
- ✔ Horn honks randomly or doesn’t work when pressed.

Installation and Post-Install Notes
The BCM is typically located under the driver’s side of the dashboard (LH dash) on most trucks and full-size SUVs like the Suburban, Tahoe, and Silverado. On S-series trucks and SUVs like the S10 and Blazer, it’s often found in the center dash area. While installation is straightforward for most DIY mechanics, please be aware of potential post-installation procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, interior and exterior lighting, the anti-theft system, wipers, and other comfort and convenience features.
Is this module difficult to install?
For someone with basic mechanical skills, the physical installation is typically not difficult. It involves removing a few dash panels to access the module, unplugging the electrical connectors, and swapping the unit. The main challenge, which we solve, is the electronic programming.
Do I need to do any programming myself?
No. We handle all the programming before we ship the part. You just need to provide us with your vehicle’s 17-digit VIN when you place your order. The module will arrive ready to be installed.
What happens if I forget to provide my VIN?
We cannot ship your order without a VIN. The programming is essential for the module to communicate with your vehicle. Our customer service team will contact you to get the necessary information if it’s missing from your order.
Why is my airbag light on after installing the new BCM?
The BCM and the airbag system (SDM) are linked for security. If the airbag light appears, the modules need to be electronically ‘introduced’ to each other. This requires a ‘Setup SDM Primary Key in BCM’ procedure with a high-level scan tool.
Is this part compatible with part numbers 9371990 and 9385236?
Yes, this module is a direct replacement for service numbers 19208539, 9371990, and 9385236, covering a wide range of GM trucks and SUVs from the 2000-2001 model years.
