Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating and unpredictable electrical problems in your GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a no-start condition can all point to a single culprit: 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 issues. This replacement BCM, compatible with part number 8162571250 and others, is the definitive solution to restore your vehicle’s reliability and functionality.
From the Diagnostic Bay
We had a 1999 Silverado 1500 come into the shop with a classic ghost-in-the-machine problem. The owner complained of the dome light staying on, the radio randomly shutting off, and the power door locks working only intermittently. He had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication error codes pointing towards the BCM. Instead of a complex and costly diagnostic chase, we installed a VIN-programmed BCM. The moment it was connected and the battery was re-hooked, all the phantom electrical issues vanished. It’s a testament to how a single, properly functioning module can bring a vehicle back to life.
Common Symptoms of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM is the likely cause. This module is a direct replacement that solves these common problems:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting, such as dome lights staying on or headlights flickering.
- ✔ Malfunctioning windshield wipers or washers.
- ✔ Security system faults, including the horn sounding randomly or the engine refusing to start (PassLock issues).
- ✔ Inoperative remote keyless entry (RKE) fobs.
- ✔ Warning lights on the dashboard, such as the airbag or brake light, without an actual fault in those systems.
- ✔ Communication errors with other modules when checked with a diagnostic scan tool.
The Plug-and-Play Solution: A Pre-Programmed 1998-2000 GM BCM
Dealerships and many repair shops require you to buy a new module and then pay for several hours of labor to program it to your vehicle. Our process eliminates that hassle and expense. When you order from us, you provide your vehicle’s VIN (Vehicle Identification Number). Our technicians then flash the module with the latest, most stable software directly from GM, ensuring it is perfectly matched to your truck’s specific options and configuration. This means that for most functions, the installation is a simple plug-and-play process. You receive a part that is ready to be installed right out of the box, saving you time, money, and a trip to the dealer.
Installation and Post-Install Procedures
Replacing the BCM is a manageable task for a DIY mechanic with basic tools. The module is typically located under the driver’s side or center of the dashboard. After disconnecting the battery, you simply unplug the electrical connectors from the old BCM, remove it, and install the new one in its place. Once the new module is connected and the battery is reconnected, you may need to perform a couple of simple procedures:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This is because the new BCM needs to be electronically ‘introduced’ to the airbag’s SDM (Sensing and Diagnostic Module). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and clear the light.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary. This can often be done with a capable bidirectional scan tool.
We make the process even easier with our no core charge policy. You don’t have to worry about the cost or hassle of sending your old, faulty module back to us. Keep it, recycle it, or dispose of it as you see fit.
Guaranteed Fitment
This BCM is a direct replacement for a wide range of popular GM trucks, vans, and SUVs from 1998 to 2000. It is crucial to match the ID number 16257125 found on your original part or provide us with your VIN to guarantee compatibility. This module fits:

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, interior/exterior lights, the security system, wipers, and more.
Why do I need to provide my VIN?
Providing your VIN is essential. We use it to program the BCM with the correct software and settings for your vehicle’s specific features and options. This ensures a plug-and-play installation and proper functionality.
Is this a difficult part to install?
For someone with basic mechanical skills, the physical installation is straightforward. It involves disconnecting the battery, accessing the module under the dash, and swapping the electrical connectors. The post-installation procedures may require a professional scan tool.
What happens if I don’t perform the post-installation procedures?
If the airbag light is on, it will stay on until the sync procedure is completed, and the airbag system may not function correctly. If the brake pedal position isn’t relearned, you might experience issues with brake light operation or traction control.
Will this BCM fix my specific problem?
This module is the solution for issues directly caused by a failing BCM, such as the common symptoms listed above. While it resolves the vast majority of electrical problems, you should always ensure your vehicle’s wiring and related components (like switches and motors) are in good condition.
