Restore Full Electrical Control to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your truck? Flickering lights, malfunctioning power windows, a security system that acts on its own, or an intermittent no-start condition can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and unpredictable problems. This replacement Body Control Module, part number 9366801, is the definitive solution to restore your vehicle’s factory functions and get you back on the road with confidence.
We had a 1999 Sierra 1500 come into the shop that was driving the owner crazy. The dome light would stay on, the radio presets would randomly reset, and sometimes the power locks wouldn’t respond. He had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw a dozen communication error codes all pointing back to the BCM. Instead of a complex and costly wiring chase, we installed a VIN-programmed BCM. Within an hour, every single one of the truck’s quirky electrical issues was gone. It’s a reminder that sometimes the most baffling problems have a straightforward, central solution.
Is Your Silverado’s BCM Failing?
The Body Control Module manages a wide array of non-engine-related functions. A faulty BCM can manifest in numerous ways. Check if your vehicle is experiencing any of the following:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting, including headlights, taillights, or dome lights.
- ✔ The security system or anti-theft light flashing incorrectly or preventing the engine from starting.
- ✔ Inconsistent or non-functional windshield wipers and washers.
- ✔ Dashboard warning lights that illuminate for no reason.
- ✔ Problems with the radio, climate control, or other interior accessories.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.
The Plug-and-Play Solution: A VIN-Programmed 1999-2000 Silverado BCM
Don’t settle for a junkyard part that might have the same issues as your old one, or a generic module that requires expensive dealer programming. We take the guesswork and hassle out of the repair. When you order from us, simply provide your vehicle’s 17-digit VIN. Our technicians will program this BCM with the latest GM software specific to your truck’s exact build. This ensures that it communicates perfectly with your vehicle’s other modules right out of the box, making installation as simple as possible. Plus, there is no core charge, so you can keep your original module without the hassle of sending it back.
Installation and Post-Install Considerations
This BCM is typically located under the driver’s side of the dashboard. While the physical replacement is straightforward for a DIYer with basic tools, there are a few potential post-installation procedures to be aware of:
- Airbag System Sync: In some cases, the new BCM may need to be synchronized with the vehicle’s airbag system (SDM). 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 is a quick process for any qualified technician.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary. This procedure can also be completed with a compatible diagnostic tool.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these body-related functions.
Do I need to get this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN during checkout, and we will flash the module with the correct software for your specific vehicle, making it ready for installation.
What happens if I forget to provide my VIN?
Providing your VIN is essential for the programming process. If you do not provide it, we cannot program the module, which will delay the shipment of your order. We will contact you to retrieve the VIN before processing.
Why is my airbag light on after installing the new BCM?
The BCM communicates with the airbag system (SDM). After replacement, these two modules may need to be electronically re-introduced. This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool to clear the light.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, which saves you time and money on return shipping.
