Is Your Silverado 3500 Experiencing Bizarre Electrical Issues?
If your truck’s lights are flickering, windows won’t respond, or your HVAC system has a mind of its own, you’re likely dealing with a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and seemingly unrelated problems. This VIN-programmed GM 25844480 BCM is the definitive solution to restore full electrical functionality to your 2007-2013 GM truck or SUV, including the Chevrolet Silverado, GMC Sierra, Tahoe, and Escalade.
Symptoms of a Failing GM Body Control Module
- ✔ Unresponsive or erratic power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ HVAC and climate control systems failing to operate or blowing air incorrectly.
- ✔ An active airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Malfunctioning security system, leading to no-start conditions or random alarm activation.
- ✔ Intermittent wiper operation or wipers that won’t turn off.
