Restore Your Vehicle’s Electrical System with Confidence
Are you battling frustrating electrical gremlins in your Trailblazer, Rainier, or Envoy? Flickering lights, malfunctioning power windows, a dead instrument cluster, or accessories that have a mind of their own are all classic signs of a failing Body Control Module (BCM). Don’t let these unpredictable issues compromise your vehicle’s reliability. This direct-fit BCM is the definitive solution to get your SUV’s electronics back in perfect working order.

A faulty BCM is the hidden cause behind some of the most confusing automotive problems. If you’re experiencing any of the following, this module is the part you need:

Frequently Asked Questions
What information do you need from me after I order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your BCM without it. This ensures the module is correctly configured for your specific options and systems.
Is this a difficult part to install?
For someone with moderate mechanical experience, the installation is very manageable. The BCM is typically located as part of the front fuse box assembly. The key is to disconnect the vehicle’s battery before starting. Because our module is pre-programmed, you avoid the most difficult part of the job—the software configuration.
What if my airbag light is on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). This is done with a professional scan tool using a procedure called ‘Setup SDM Primary Key in BCM’. This is a simple procedure for any qualified repair shop if the light appears.
Do I have to return my old BCM?
No. This product has no core charge. You can keep, discard, or recycle your original module at your convenience.
Will this BCM fix my exact problem?
This module will correct issues directly caused by a failing BCM. While the symptoms listed are very common for BCM failure, it’s always essential to have your vehicle properly diagnosed. This 25802312 BCM is the solution when the module itself has been identified as the point of failure.
What other procedures might be needed after install?
Depending on your specific model, a Brake Pedal Position Sensor recalibration might be necessary. This ensures your brake lights and traction control system function correctly. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
