Restore Full Electronic Functionality to Your GM Truck
Are you battling persistent and frustrating electrical issues in your vehicle? Flickering lights, malfunctioning power windows and locks, or a security system that prevents your truck from starting are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement Body Control Module, compatible with part numbers 19208539, 9371990, and 9385236, is the definitive solution to restore your vehicle’s proper operation.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program this module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures seamless communication with your truck’s other electronic systems, eliminating the need for expensive programming at a dealership. Simply provide your VIN after purchase, and we’ll handle the rest, loading the latest GM software updates for optimal performance and reliability.
From the Diagnostic Bay
We recently had a 2000 GMC Sierra in the shop with a classic “parasitic draw” issue – the battery would be dead every morning. The owner had already replaced the battery and alternator twice. After hours of tracing circuits, we found the culprit: the original BCM was keeping the interior lighting relay energized long after the doors were closed. It was a subtle fault that was hard to find but easy to fix. Installing a correctly programmed 2000 Silverado BCM not only solved the battery drain but also fixed an intermittent power lock issue the owner had forgotten to mention. Proper diagnosis points to the BCM more often than you’d think.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways, often mimicking other problems. If your truck is experiencing any of the following, a failing BCM is the likely cause:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The security system activating randomly or causing a no-start condition (security light flashing).
- ✔ Intermittent or non-functional radio and climate controls.
- ✔ False warnings on the instrument cluster, such as a “door ajar” light that won’t turn off.
- ✔ Horn honking unexpectedly or not working when pressed.
The Plug-and-Play Solution for Your 2000 Silverado BCM
Replacing your BCM doesn’t have to be a complicated ordeal. Our streamlined process makes it simple. Once you place your order, we’ll ask for your VIN. Our technicians then use that information to flash the module with your vehicle’s exact configuration and the most current software from GM. This ensures that when the part arrives, it’s ready for a straightforward installation. For most models, the BCM is located on the left-hand (driver’s) side of the dashboard, making it accessible for replacement.
Important Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require additional steps after the new BCM is installed. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related electronic functions. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and more.
Is this part difficult to install?
The physical installation is typically straightforward for someone with basic mechanical skills. The BCM is usually located under the driver’s side dashboard. However, due to the potential need for post-installation procedures like an airbag sync, we recommend professional installation if you are not comfortable with automotive electronics.
How do I provide my VIN for programming?
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 essential for the part to function correctly.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if the airbag light comes on after I install it?
This indicates that the BCM needs to be synchronized with the airbag’s Sensing and Diagnostic Module (SDM). A procedure called “Setup SDM Primary Key in BCM” must be performed with a professional-grade diagnostic tool to resolve this.
