Is Your GM Truck or SUV Experiencing Bizarre Electrical Issues?
If you’re dealing with flickering lights, malfunctioning power windows, a stubborn security system, or other strange electrical gremlins in your late 90s GM truck or SUV, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, coordinating everything from the interior lights and power locks to the anti-theft system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems.
Common Symptoms of a Failing GM BCM 16257125
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior (lights staying on or not turning on).
- ✔ Security system issues, including a flashing security light or a no-start condition due to Passlock failure.
- ✔ Wipers or radio acting strangely or not responding to controls.
- ✔ False warning lights on the instrument cluster, such as the airbag light.
- ✔ Inoperative keyless entry remote fobs.
- ✔ Diagnostic trouble codes (DTCs) pointing to BCM failure or loss of communication.
The Direct-Fit, Programmed Solution
Don’t let a faulty BCM keep your truck off the road or make driving a hassle. This replacement Body Control Module is the definitive solution. We eliminate the biggest hurdle in BCM replacement: programming. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest GM-certified software specific to your truck’s configuration. This means the module arrives at your door ready for a straightforward installation, completely bypassing the need for an expensive trip to the dealership and their proprietary scan tools.
This module is a direct replacement for a wide range of popular GM vehicles, including the Chevy S10, Blazer, Silverado, GMC Sonoma, Jimmy, Sierra, and Isuzu Hombre. It is compatible with multiple part numbers, including 19153625, 8191536250, 16257125, 191583625, 8093668010, 8162571250, and 09366801.
Installation and Post-Install Considerations
The BCM is typically located under the dashboard, either in the center or on the driver’s side (LH dash). While the physical installation is a simple plug-and-play process, some vehicles may require additional electronic relearn procedures after the new module is connected. These are not always necessary but are important to be aware of:
- Airbag System Sync: If your airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor may be required to ensure correct brake light operation and proper function of the traction control system.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation or post-installation process. With our pre-programmed GM BCM 16257125, you can confidently restore your vehicle’s full electronic functionality and get back on the road with peace of mind.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls various electronic accessories not related to the engine. This includes power windows, locks, mirrors, interior/exterior lighting, the security system, and wipers.
Do I need to get this programmed at the dealership?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This makes it a plug-and-play solution, saving you the time and expense of a dealership visit.
Where is the BCM located on my truck or SUV?
On most compatible models like the S10, Blazer, Silverado, and Sierra, the BCM is located under the dashboard, either in the center console area or on the driver’s side (LH dash).
What happens if I don’t provide my VIN?
Providing your VIN is mandatory for this part. We cannot program and ship the BCM without it, as the software is specific to your vehicle’s factory options. Failure to provide a VIN will delay your order.
Will this fix my security light and no-start issue?
A faulty BCM is a very common cause of a flashing security light and a no-start condition in these GM vehicles due to the Passlock anti-theft system. If the BCM is the root cause of the problem, this programmed module will resolve the issue.
What if the airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically synced with the airbag module (SDM). This procedure, called ‘Setup SDM Primary Key in BCM’, requires a professional scan tool and can be performed by most automotive repair shops.
