From the Diagnostic Bay
We had a 1999 Silverado in the shop that was driving the owner crazy. Every few days, he’d find his battery completely dead. He had already replaced the battery twice and the alternator once, but the mysterious parasitic drain continued. After hooking up an ammeter, we pulled fuses one by one until we isolated the circuit. The drain was coming from the interior lighting circuit, even though all the lights were off. The culprit? A faulty BCM that was keeping the circuit energized long after the key was removed. A new, programmed BCM solved the problem instantly, saving the customer from throwing more parts at a phantom issue.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or won’t turn on at all.
- ✔ The security system (Passlock) acts up, preventing the vehicle from starting.
- ✔ Instrument cluster gauges behaving erratically or not working.
- ✔ The radio or climate control system functions intermittently.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ A persistent battery drain that kills the battery overnight.
Why Choose Our Programmed 1998-2000 GM BCM?
When you’re dealing with a critical electronic component like the BCM, a generic, off-the-shelf part won’t work. Our service provides a fully tested module that has been precisely configured for your vehicle’s specific options and features using your VIN. This commitment to vehicle-specific programming is what separates a quick, successful repair from a frustrating, dead-end installation. This 1998-2000 GM BCM is your reliable path to resolving those nagging electrical gremlins for good.
Simple Installation Process
Installation is designed to be as straightforward as possible. The BCM is typically located under the driver’s or passenger’s side of the dashboard. After disconnecting the battery, you simply unplug the wiring harnesses from your old module, remove it, and install the new one in its place. Once the new module is connected and the battery is reconnected, you’re nearly done. In some cases, a few simple post-installation procedures may be required.
Post-Installation Notes:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
- No Core Charge: You are not required to return your old, faulty module. There is no core charge or deposit associated with this purchase.

Frequently Asked Questions
Do I need to have this BCM programmed?
No. We handle all the programming for you before shipment. Just provide your vehicle’s VIN at checkout, and the module will arrive ready to install.
Where is the BCM located on my vehicle?
On most compatible models like the S10, Blazer, Silverado, and Sierra, the BCM is located behind the dashboard, often on the driver’s side (LH dash) or in the center dash area. Always consult a service manual for the exact location on your specific model.
What happens if I install this without programming?
An unprogrammed BCM will not work correctly. It won’t recognize your vehicle’s specific options, security system, or other modules, leading to a no-start condition or incorrect function of various features. Our pre-programming service eliminates this issue.
Will this fix my Passlock security light and no-start problem?
A faulty BCM is a very common cause of Passlock security system issues. While not a guarantee for every situation, replacing a failed BCM with our programmed unit often resolves these security-related starting problems.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a high-level, bi-directional diagnostic scan tool, such as a GM Tech 2 or equivalent professional equipment. Many local repair shops can perform these relearn procedures for you if needed.
