Restore Your Truck’s Electrical System and Get Back on the Road
Are strange electrical issues making your dependable GM truck feel unreliable? If you’re dealing with flickering lights, unresponsive power windows and locks, or a security system that has a mind of its own, a failing Body Control Module (BCM) is the most likely culprit. This isn’t just an annoyance; it’s a problem that can disrupt your daily work and routine. This pre-programmed BCM is the definitive, straightforward solution to restore your vehicle’s core functions and your peace of mind.
Common Symptoms & Your Solution
A faulty BCM can cause a cascade of frustrating problems that seem unrelated. If you’re experiencing any of the following, this module is the fix you need:
- Intermittent or non-working power windows, door locks, or mirrors
- Interior dome lights or dashboard lights staying on or not working at all
- The security light flashing, preventing the truck from starting (PassLock issues)
- Erratic radio or climate control behavior
- False warning lights on the instrument cluster

Expert Insight: The Dealership Alternative
As a technician, I’ve seen countless owners spend hundreds at the dealership just for a BCM diagnosis and programming fee, on top of the part cost. The vehicle is often out of commission for days. Our approach cuts out the complexity. By programming the module to your VIN before it even ships, we eliminate the most difficult step. You receive a part that’s ready to be installed, saving you significant time, money, and the headache of scheduling a dealer appointment. Itโs the smart, efficient fix for the practical truck owner.
Important Post-Installation Information
While this 1999-2000 GMC Sierra 1500 BCM is designed for a simple installation, some vehicle systems may require a quick sync procedure afterward. Please note the following:
- 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 module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation.
We provide the most critical componentโa properly programmed module. These minor, vehicle-specific sync procedures are standard practice when replacing a central computer. For a trouble-free experience with your 1999-2000 GMC Sierra 1500 BCM, always consult your vehicle’s service manual or a qualified mechanic if you are unsure about these final steps.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is specific to your truck.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the physical replacement is straightforward. The BCM is typically located under the driver’s side or center of the dashboard. The main challenge is typically the programming, which we have already done for you. However, please review the potential post-installation procedures mentioned above.
What happens if the airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to your vehicle’s airbag module (SDM). A repair shop with a professional-grade diagnostic tool (like a Tech 2 or equivalent) can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Will this fix my truck’s security (PassLock) issue?
Yes, a failing BCM is one of the most common causes of PassLock security system problems in these GM trucks, which can prevent the engine from starting. Replacing it with a correctly programmed unit is a primary solution for this issue.
Do I need to do anything with my keys?
No, the key data is not stored in the BCM on these models. Your original keys will continue to work without any additional programming required.
