Is Your GM Truck Experiencing Bizarre Electrical Issues?
If your late 90s or early 2000s GM truck or SUV is acting possessed—with flickering lights, malfunctioning power windows, a security system that won’t cooperate, or random warning lights on the dash—the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. Don’t let these electrical gremlins sideline your reliable truck. We offer a direct-fit, VIN-programmed replacement BCM that restores full functionality and gets you back on the road with confidence.
From the Diagnostic Bay
We had a 1999 Sierra 1500 come into the shop that was driving the owner crazy. The dome light would stay on, the radio would randomly shut off, and the power locks worked only when they wanted to. The owner had already replaced the battery and checked all the fuses. After hooking up our scanner, we saw multiple communication error codes pointing towards the BCM. Instead of a costly and time-consuming trip to the dealer, we installed one of our pre-programmed BCMs. Within an hour, every single one of the truck’s electrical gremlins was gone. It’s a common story for these vehicles, and a new BCM is almost always the definitive fix.
Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (dome lights, headlights, or taillights).
- ✔ Malfunctioning security system or horn that honks randomly.
- ✔ Inoperative radio or climate control functions.
- ✔ False warning lights on the instrument cluster, such as the airbag or brake light.
- ✔ Problems with the Passlock anti-theft system, causing no-start conditions.
- ✔ Inaccurate fuel gauge or other instrument panel readings.
The Simple, Reliable Solution: A VIN-Programmed Module
Dealerships can charge a fortune for a new BCM, plus additional fees for programming and installation. Our solution saves you time and money. This is a replacement Body Control Module that arrives at your door programmed specifically for your vehicle. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will flash the module with the latest GM software updates and your vehicle’s exact configuration. This ensures a seamless installation process, often referred to as ‘plug-and-play,’ getting your truck’s essential features working correctly again.
Why Choose Our 1999-2000 Silverado BCM?
This isn’t just a replacement part; it’s a comprehensive solution. By programming the module before shipping, we eliminate the need for expensive scan tools or a trip to the dealership. This module is tested to ensure it meets or exceeds original equipment standards for performance and reliability. Plus, with our no-core-charge policy, you can keep your old module without any extra hassle or hidden fees.
Installation and Post-Install Procedures
Installation is straightforward for anyone with basic mechanical skills. The BCM is typically located under the driver’s side dashboard. After disconnecting the battery, simply unplug the electrical connectors from your old BCM, remove it, and install the new one. Reconnect the connectors and the battery.
Important Note: In some cases, additional steps may be required after installation:
- Airbag System Sync: If the airbag warning light illuminates 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: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
Do I need to send you my old BCM?
No, there is no core charge for this part. You can keep your original module.
Is this module difficult to install?
Installation is a simple plug-and-play process. It involves disconnecting the battery, swapping the modules under the dash, and reconnecting the battery. However, some vehicles may require a post-installation procedure with a scan tool for the airbag or brake systems.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it.
What happens if the airbag light comes on after installation?
This indicates the new BCM needs to be synchronized with the vehicle’s airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed using a professional-grade diagnostic tool.
Will this fix my truck’s no-start problem?
A failing BCM is a very common cause of no-start issues related to the Passlock anti-theft system in these GM vehicles. Our VIN-programmed BCM is designed to correctly integrate with your vehicle’s security system and can resolve these problems.
