Tired of Chasing Electrical Gremlins in Your GM Truck?
If your late-90s Chevy, GMC, or Isuzu is suffering from bizarre electrical issues like flickering interior lights, unresponsive power locks, a security light that won’t turn off, or intermittent starting problems, a failing Body Control Module (BCM) is the most likely culprit. These modules are the central hub for your vehicle’s body electronics, and after two decades of service, their internal components can begin to fail, leading to frustrating and unpredictable behavior. Stop throwing parts at the problem and get the definitive solution with our professionally programmed 16257125 BCM.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways, often making you think multiple components have failed at once. If you’re experiencing any of the following, this module is your answer:
- Erratic or non-functional interior dome lights and courtesy lamps.
- Power door locks that work intermittently or not at all.
- The security or anti-theft light stays on, potentially causing a no-start condition.
- Inconsistent radio or climate control operation.
- False door ajar warnings on the instrument cluster.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a reliable BCM core and flash it with the latest official GM software calibrated specifically to your vehicle’s VIN. This process ensures all factory-installed options work correctly right out of the box, saving you a costly trip to the dealership for programming.

An Expert’s Note on BCM Replacement
As a technician, I’ve seen countless hours wasted trying to diagnose these exact issues on S10s, Silverados, and Blazers. A customer might come in complaining about a dead battery, and you find the courtesy lights are staying on due to a bad BCM. Or they can’t lock their truck, and it’s not the switch—it’s the module. The beauty of a pre-programmed unit is that it eliminates guesswork. For a DIYer, it turns a potentially complex electronic repair into a simple component swap. For a professional shop, it’s a reliable, efficient fix that gets the customer’s truck back on the road faster. This is the correct way to solve the problem.
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 and exterior lighting, security systems, and wipers. When it fails, these systems can behave erratically.
What happens after I place my order?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive it. Once we have your VIN, our technicians will program the module with the correct software and vehicle-specific options before shipping it to you.
Is this part difficult to install?
For most of the listed vehicles, the BCM is located under the dash and is accessible with basic hand tools. Since our module comes pre-programmed, installation is typically a plug-and-play process. However, we always recommend consulting a service manual for your specific vehicle or seeking help from a qualified mechanic if you are unsure.
Do I need to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this purchase, which simplifies the process for you.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to turn off the light.
