Is Your GM Truck Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. Don’t let a faulty module sideline your reliable truck. This VIN-programmed BCM is the definitive solution to restore full functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ The security or anti-theft system (VATS) preventing the engine from starting.
- ✔ The “Security” light flashing or staying illuminated on the dashboard.
- ✔ Horn honking randomly or the alarm system activating without cause.
- ✔ Intermittent issues with the radio or climate control displays.
- ✔ False warning messages appearing on the driver information center.
The Easiest Solution: A VIN-Programmed 1999-2000 Sierra BCM
Replacing the BCM on these GM trucks used to mean a trip to the dealership for expensive diagnostics and programming. We’ve eliminated that hassle. When you order from us, you provide your vehicle’s VIN, and we program the module specifically for your truck’s factory options and security key information. It arrives at your door with the latest GM software updates, ready for a straightforward installation. This is the most efficient and cost-effective way to solve your vehicle’s electrical problems.
Installation and Post-Install Considerations
Physically swapping the module is typically simple. After disconnecting the battery, the BCM is usually located behind the lower-left portion of the dashboard. However, due to the integration of various vehicle systems, a couple of post-installation procedures may be necessary:
- Airbag System Sync: If your airbag warning light is on 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 some models, a brake pedal position sensor recalibration might be required to ensure proper brake light and traction control function.
Best of all, there is no core charge for this part. You can keep your original module without the hassle of shipping it back.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your truck’s specific options, such as keyless entry, power accessories, and the correct anti-theft key data. This ensures it works correctly right out of the box.
Is this a plug-and-play part?
Yes, it is programmed to be plug-and-play. The physical installation is simple. However, as noted above, some vehicles may require an airbag system sync or brake pedal position relearn with a professional scan tool to clear warning lights.
Will this fix my flashing ‘Security’ light and no-start problem?
A faulty BCM is the most common cause of these specific symptoms on this generation of GM trucks. By programming the module to your VIN, we match it to your vehicle’s security system, making this a highly effective solution for that problem.
Where is the BCM located on my truck?
On most models like the Sierra and Silverado, the BCM is located on the driver’s side, behind the lower dash panel near the steering column. On S-series trucks and SUVs, it is often found in the center dash area.
Do I need to send my old BCM back?
No. This product comes with no core charge, so you can keep your original module without any additional cost or hassle.
