Restore Full Functionality to Your GM Truck or SUV
Are you battling frustrating electrical problems in your late 90s GM truck or SUV? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or an intermittent no-start condition 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 fails, it can cause a cascade of confusing and unpredictable issues. This replacement Body Control Module, part number 16257125, is the definitive solution to get your vehicle back in reliable, working order.
From the Diagnostic Bay
We had a 1999 Silverado in the shop that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and the power door locks had a mind of their own. The owner had already replaced the door lock actuators and the headlight switch, but the problems persisted. After hooking up our diagnostic tool, we saw multiple communication error codes pointing to a single source: the BCM. A faulty BCM can send confusing signals throughout the vehicle, making you chase ghosts. Installing a properly programmed module fixed every single issue in one go, saving the customer from further frustration and unnecessary parts expenses.
Why Choose Our Pre-Programmed GM Truck BCM?
Don’t settle for a generic module that requires expensive trips to the dealership for programming. We take the hassle out of the repair. When you purchase from us, we flash the module with the latest GM software updates, specifically coded to your vehicle’s unique Vehicle Identification Number (VIN). This ensures seamless integration and proper function of all your vehicle’s features right out of the box. This is a true plug-and-play solution designed for a straightforward installation process.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or anti-theft light flashing, preventing the engine from starting.
- ✔ The radio or instrument cluster gauges behaving erratically.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Diagnostic trouble codes related to communication errors (U-codes).
Installation and Post-Install Procedures
This BCM is typically located behind the dashboard, either in the center or on the driver’s side (LH dash). While the physical replacement is straightforward, please be aware of potential post-installation steps. Because this module communicates with other critical systems, some vehicles may require a relearn procedure to sync everything correctly.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control performance.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process. This pre-programmed GM Truck BCM is a direct replacement for a wide range of original part numbers, including: 19153625, 8191536250, 16257125, 191583625, 8093668010, 8162571250, and 09366801.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN during checkout, and we will flash the module with the latest GM software specific to your truck or SUV.
What is a BCM and what does it control?
The Body Control Module (BCM) is a computer that manages your vehicle’s non-engine-related functions. This includes power windows, door locks, interior/exterior lighting, the security system, wipers, and the instrument panel.
Where is the BCM located on my vehicle?
On most compatible models like the Silverado, Sierra, S10, and Blazer, the BCM is located behind the dashboard, either in the center console area or on the driver’s side (LH dash).
What if my airbag light turns on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system’s computer. A technician with a professional-grade scan tool will need to perform a quick ‘Setup SDM Primary Key in BCM’ procedure to sync the modules.
Is there a core charge for this part?
No, there is absolutely no core charge. You can keep your old, original module without any extra fees or hassle.
How do I give you my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your VIN. We cannot ship your order until we receive the VIN to ensure the BCM is programmed correctly for your specific vehicle.
