Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your truck? Intermittent power windows, flickering dash lights, or a security system that randomly prevents your engine from starting are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and unpredictable issues. This module is a direct-fit, professionally programmed solution for your 1999-2000 Silverado 2500 and many other GM models, designed to restore your vehicle’s functions and your peace of mind.
From the Diagnostic Bay
We recently had a ’99 Sierra 1500 in the shop that was driving its owner crazy. The main complaint was a dead battery every morning. He’d already replaced the battery and alternator, but the problem persisted. Our diagnostics traced the parasitic draw back to the BCM, which was keeping the interior lights and retained accessory power active long after the key was out. A simple swap with a VIN-programmed BCM like this one solved the issue instantly, saving the customer from further guesswork and expensive part replacements. It highlights how a single faulty module can mimic a dozen other problems.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. Replacing it can resolve these persistent electrical headaches.
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Vehicle security system (Passlock/VATS) preventing the engine from starting.
- ✔ Inconsistent or malfunctioning dashboard warning lights.
- ✔ Wipers operating incorrectly or getting stuck.
Why Choose Our 1999-2000 Silverado BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra expense out of the repair. Before we ship your module, our technicians will program it using your vehicle’s unique Vehicle Identification Number (VIN). This critical step ensures the BCM has the latest software updates from GM and is correctly configured for your truck’s specific options and features. This eliminates the need for a costly trip to the dealership for programming, making the installation process as straightforward as possible.
Simple Installation Process
Installation is typically a plug-and-play process. The BCM is usually located under the driver’s or passenger’s side of the dashboard. Once you’ve swapped the module, you may need to perform a couple of simple relearn procedures depending on your specific model.
- Airbag System Sync: If your airbag warning light illuminates after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that supervises and controls various electronic accessories in your vehicle’s body, such as power windows, locks, interior/exterior lighting, security systems, and wipers.
Do I need to take this part to a dealer for programming?
No. We program the module to your vehicle’s VIN before shipping it to you. It arrives ready for installation, saving you the time and expense of a dealership visit.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship the module until we have this information to perform the programming.
Where is the BCM located on my 1999 Silverado?
On most 1999-2000 Silverado and Sierra models, the BCM is located under the driver’s side of the dashboard, to the left of the steering column.
What if the airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag control module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back.
