Are you battling a storm of electrical gremlins in your GM truck or SUV? Flickering lights, unresponsive power windows, a malfunctioning HVAC system, or a persistent airbag light can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause widespread and frustrating issues. This genuine GM Body Control Module, interchangeable with part number 25844480, is the definitive solution for restoring your vehicle’s electronic functions to perfect working order.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely cause:
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ HVAC system failures, including a blower motor that won’t work or climate controls that are inoperative.
- ✔ An illuminated airbag warning light, often accompanied by DTC B1001.
- ✔ Security system malfunctions, causing no-start conditions or random alarm activation.
- ✔ Wipers that behave erratically or don’t work.

Installation and Post-Install Procedures
Installation is typically a simple plug-and-play process. The BCM is located under the driver’s side dashboard, near the steering column. In most cases, it takes only a few minutes to swap the modules. However, please be aware of potential post-installation steps:
- Airbag System Sync: If the airbag warning light is on 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.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
We’ve eliminated the need for a core charge, so you can keep your old part without any extra hassle. For a smooth repair, always check for and resolve any potential grounding issues during installation.
