Restore Full Control of Your Truck’s Electronics
Are you battling bizarre electrical issues in your GM truck? Flickering dashboard lights, power windows with a mind of their own, or a security light that prevents your engine from starting can be incredibly frustrating. These aren’t just annoyances; they’re symptoms of a failing Body Control Module (BCM), the electronic nerve center of your vehicle. This pre-programmed BCM is the definitive, hassle-free solution to get your dependable truck back in perfect working order.
Common Symptoms & Your Solution
If your truck is experiencing any of the following, a failing BCM is the likely culprit. This module is the direct solution for:
- Intermittent or non-functional power windows, door locks, and interior lights.
- Erratic gauge behavior or warning lights that stay on for no reason.
- Problems with the Passlock security system, causing a no-start condition.
- Radio or climate control malfunctions.
- Communication issues with other vehicle modules (often indicated by U-series diagnostic trouble codes).
Instead of paying for expensive diagnostic time and programming fees at a dealership, this unit arrives flashed with the latest GM software and coded specifically to your vehicle’s VIN. This makes the installation on your 1999-2000 Silverado 1500 BCM as straightforward as possible.

Expert Insight: Why VIN Programming is Non-Negotiable
On these late 90s and early 2000s GM trucks, the BCM is a critical part of the Passlock anti-theft system. Simply swapping a BCM from another vehicle won’t work—the truck will not start because the security credentials won’t match the ignition key and PCM. In the past, your only option was to install a new module and have a dealer perform a security relearn and programming procedure. By programming this 1999-2000 Silverado 1500 BCM to your specific VIN before we ship it, we handle that complex step for you. This transforms a dealer-level job into a manageable DIY repair, putting you back in control.
Frequently Asked Questions
What information do you need from me?
After you place your order, we will need the 17-digit Vehicle Identification Number (VIN) from your truck. This is essential for us to program the BCM correctly for your specific vehicle options and security system.
Is this BCM difficult to install?
The BCM is typically located under the driver’s side of the dashboard. Installation involves disconnecting the battery, removing a few trim panels for access, and swapping the electrical connectors. It is a manageable job for a confident DIYer with basic hand tools. However, always consult a service manual for your specific model’s procedure.
What if my airbag light is on after installation?
In some cases, the new BCM needs to be synced with the airbag system (SDM). If the airbag warning light comes on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick procedure for any qualified repair shop.
Do I need to return my old BCM?
No. We do not require you to send back your original part. There is no core charge or deposit associated with this purchase.
Will this fix my no-start problem?
If your no-start issue is caused by the factory security system (often indicated by a flashing ‘Security’ or ‘Theft’ light), this pre-programmed 1999-2000 Silverado 1500 BCM is a very common and effective solution, as it restores proper communication within the anti-theft system.
