Restore Your Truck’s Electrical System to Perfect Working Order
Are you battling frustrating electrical gremlins in your GM truck or SUV? Flickering lights, malfunctioning power windows, or a security system that prevents your vehicle from starting are all common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and unpredictable issues. This replacement BCM is the definitive solution to restore full functionality and reliability to your vehicle, getting you back on the road with confidence.
This isn’t just a generic part off the shelf. We provide a fully programmed BCM tailored specifically to your vehicle. Upon purchase, simply provide us with your Vehicle Identification Number (VIN), and our technicians will flash the module with the latest, most stable software updates directly from GM. This ensures seamless integration and communication with your truck’s existing systems, making installation as straightforward as possible.
Is Your GM Truck Showing Signs of a Faulty BCM?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following issues, a faulty Body Control Module is the most likely culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior dome lights or exterior headlights and taillights.
- ✔ The security light on the dashboard stays on or flashes, potentially leading to a no-start condition.
- ✔ Windshield wipers or washers activating randomly or not working when commanded.
- ✔ The horn sounding unexpectedly or failing to work at all.
- ✔ False warnings on the instrument cluster, such as a persistent “door ajar” light.
- ✔ Problems with the radio or other accessory power functions.

Post-Installation Procedures
While this module is designed for a straightforward installation, some vehicle systems may require a recalibration procedure after the new BCM is connected. This is a normal part of the process as the new module syncs with other components.
- Airbag System Sync: If the airbag warning light illuminates after installation, it indicates a communication mismatch between the new BCM and the Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure, which re-establishes this critical link and turns off the light.
- Brake Pedal Position Relearn: On some models, the BCM needs to relearn the position of the brake pedal sensor. This is essential for the proper operation of brake lights and the traction control system. This procedure may also require a compatible diagnostic tool.
Please consult a factory service manual or a qualified technician for detailed instructions specific to your vehicle.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready to be installed, saving you a costly trip to the dealership.
Where is the BCM located on my 1999 Silverado?
On most 1999-2000 Silverado and Sierra models, the BCM is located on the driver’s side, behind the lower left-hand side of the dashboard. On S10/Blazer models, it is typically found behind the center of the dash.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the physical installation is straightforward. It involves removing some dash panels and disconnecting electrical connectors. However, be aware that post-installation procedures like an airbag system sync may be required, which necessitates a professional scan tool.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this fix the ‘Security’ light and no-start problem?
Yes, a faulty BCM is one of the most common causes of Vehicle Anti-Theft System (VATS) or Passlock issues that trigger the security light and prevent the engine from starting. Replacing it with our programmed module is a highly effective solution for this problem.
