Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating electrical gremlins in your late 90s GM truck or SUV? Flickering lights, malfunctioning power windows, a security system that acts on its own, or intermittent warning lights 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 direct-fit replacement Body Control Module, compatible with part number 19153625 and others, is the definitive solution to restore order and reliability to your vehicle’s essential functions.
Unlike a standard replacement from a dealership or parts store, this module comes pre-programmed specifically for your vehicle. We take your vehicle’s VIN and flash the module with the latest GM software updates, ensuring perfect compatibility and function right out of the box. This critical step eliminates the need for expensive programming tools or a costly trip to the dealer, making this a straightforward repair you can trust.
From the Diagnostic Bay
A customer brought in his ’99 Silverado with a laundry list of bizarre symptoms. The dome light would stay on, the radio presets would randomly disappear, and the power locks worked only when they felt like it. He had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication errors pointing towards the BCM. Instead of a complex and costly diagnostic chase, we installed a VIN-programmed module just like this one. In under an hour, every single one of his electrical issues was gone. It’s a perfect example of how a failing 1998-2000 GM BCM can mimic a dozen other problems, and how the right part is a simple, complete fix.
Symptoms of a Failing 1998-2000 GM BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior (flickering, staying on, or not turning on).
- ✔ Malfunctioning security system or horn that honks randomly.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Warning lights (like Airbag or ABS) illuminating without a clear cause.
- ✔ Problems with the heating and A/C blower motor controls.
- ✔ Communication errors with diagnostic scan tools.
Simple Installation Process
We’ve made this repair as simple as possible. Once you place your order, simply provide us with your vehicle’s 17-digit VIN. Our technicians will program the module to match your vehicle’s specific configuration and options. When it arrives, you can install it and, in most cases, be back on the road immediately. Please note the potential post-installation procedures below:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
This module is a direct replacement for part numbers: 19153625, 8191536250, 16257125, 191583625, 8093668010, 8162571250, 09366801. Please verify your part number before ordering to ensure compatibility.
Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the BCM with the exact software and settings for your specific model, year, and options (like power windows, security system, etc.). This ensures the module works correctly right out of the box without needing a trip to the dealer.
Is this a plug-and-play part?
Yes, for the vast majority of vehicles, it is. Because we pre-program it to your VIN, it eliminates the most difficult step. However, as noted, some vehicles may require an additional relearn procedure for the airbag or brake systems, which needs a professional scan tool.
Where is the BCM located on my truck?
On most S10, Blazer, and Bravada models, the BCM is located behind the center of the dash. On Silverado, Sierra, Astro, and Safari models, it is typically found on the driver’s side, behind the lower dash panel (LH dash). Always consult a service manual for the exact location on your vehicle.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
Will this fix my ‘Service Engine Soon’ light?
Generally, no. The BCM controls body electronics, while the ‘Service Engine Soon’ or ‘Check Engine’ light is related to the engine and emissions systems, which are managed by the Engine Control Module (ECM) or Powertrain Control Module (PCM).
