Get Your Truck Back to 100%
Are you battling frustrating electrical gremlins in your truck? Flickering lights, unresponsive power windows, a security system with a mind of its own, or an instrument cluster that’s giving you fits? These are classic signs of a failing Body Control Module (BCM), the central nervous system for your vehicle’s body electronics. This replacement BCM is the definitive solution to restore the reliable, predictable performance you depend on from your GM truck or SUV.
Common Symptoms & Your Solution
A faulty BCM can cause a wide range of confusing issues that can be difficult to diagnose. If you’re experiencing any of the following, a failing module is the likely culprit:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior dome lights staying on or not turning on when they should.
- The security or anti-theft light flashing, preventing the engine from starting.
- Erratic behavior from the radio, climate controls, or dashboard gauges.
- Diagnostic Trouble Codes (DTCs) related to communication errors (U-codes).
Instead of chasing down individual component failures, address the root cause. This Programmed 1999-2000 Silverado 1500 BCM 09366801 arrives ready for installation, pre-flashed with the latest GM software and coded specifically to your vehicle’s VIN.

Expert Insight: The BCM Diagnostic Dilemma
As a technician, I’ve seen countless hours and dollars wasted chasing what appears to be a bad window switch, a faulty lock actuator, or a wiring short. The reality is, the BCM is the command center. When it starts to fail, it sends faulty signals, making other perfectly good parts seem broken. Replacing the BCM first often solves a half-dozen problems at once. This is especially true for these hard-working 90s and early 2000s GM trucks. Getting a properly programmed module like this Programmed 1999-2000 Silverado 1500 BCM 09366801 is the most efficient path to a reliable repair.
Installation & Post-Install Notes
While this module is programmed for your VIN, some vehicle systems may require a recalibration procedure after installation to sync with the new BCM. This is a normal part of the process for many modern vehicle electronics.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: On some models, a recalibration for the brake pedal position sensor may be needed to ensure correct brake light and traction control operation.
We provide this Programmed 1999-2000 Silverado 1500 BCM 09366801 to empower you to get the job done right. Always consult a service manual or a qualified technician if you are unsure about any step of the installation process.
Frequently Asked Questions
What does a BCM do on my Silverado?
The Body Control Module, or BCM, is a computer that controls most of the non-engine-related electronics in your truck. This includes power windows, door locks, interior and exterior lighting, the security system, and warning chimes.
Is this BCM truly “plug and play”?
It’s very close. We handle the main programming to your VIN, which is the most difficult part. However, as noted, some vehicles may require a simple relearn procedure for specific systems like the airbag (SDM) or brake pedal sensor after the new BCM is installed. This requires a capable scan tool.
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. Please double-check it for accuracy to ensure a perfect match.
What happens if my airbag light comes on after installation?
This is a known possibility and indicates the new BCM needs to be synced with the airbag system’s computer (SDM). A technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this and turn off the light.
Do I have to send my old part back?
No. This BCM is sold with no core charge. You can keep your original part, which saves you the time, cost, and hassle of shipping it back.
How can I be sure my BCM is the problem?
While a professional diagnosis is always best, a failing BCM is the most common cause for having multiple, unrelated electrical issues at once. If your power locks, interior lights, and security system are all acting up simultaneously, the BCM is the primary suspect.
