Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, a malfunctioning climate control system, erratic power windows, or a security light that won’t turn off, the culprit is likely 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 frustrating and seemingly unrelated issues. This genuine OEM-quality GM 25844480 BCM is the definitive solution, pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
From the Diagnostic Bay
We had a 2010 Silverado 2500 in the shop that was driving its owner crazy. The radio would turn on and off, the driver’s side power window worked only when it wanted to, and the HVAC blower was completely dead. The customer had already replaced the blower motor resistor with no luck. A quick scan revealed multiple communication codes pointing to the BCM. After installing one of our VIN-programmed modules, every single issue was resolved in under 10 minutes. It’s a common failure, but thankfully, an easy fix with the right part.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, and interior/exterior lights.
- ✔ HVAC and climate control systems not working correctly or at all.
- ✔ Airbag warning light illuminated on the dash, often with a DTC B1001 code.
- ✔ Vehicle security system malfunctions, leading to no-start or stalling conditions.
- ✔ Unexplained battery drain or parasitic draw.
- ✔ A variety of communication-related Diagnostic Trouble Codes (DTCs).

Installation & Post-Install Notes
Physical installation is simple. The BCM is located under the driver’s side dashboard, near the steering column. It can be swapped out in minutes with basic tools. While the module is plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on. This requires a professional-grade scan tool and syncs the new BCM with the airbag system. Additionally, a Brake Pedal Position relearn may be needed. Best of all, there is no core charge, so you can keep your old part without any hassle.
