Restore Full Electrical Function to Your GM Truck or SUV
Are you dealing with frustrating electrical problems in your 2007-2013 GM vehicle? A faulty Body Control Module (BCM) is often the culprit behind a wide range of issues, from flickering lights and malfunctioning power windows to a non-responsive HVAC system. This genuine OEM-quality GM 25844480 BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation. It acts as the central hub for your vehicle’s body electronics, and replacing a failing one is critical to restoring dependability and safety.
Is Your Truck’s BCM Failing?
A failing BCM can manifest in numerous ways, often seeming like multiple unrelated problems. If you’re experiencing any of the following, your BCM is the likely cause:
- ✔ Erratic or non-working interior and exterior lights.
- ✔ Power windows, door locks, or security system acting up.
- ✔ HVAC controls are unresponsive, or the blower motor works intermittently.
- ✔ The airbag warning light is illuminated, often with a DTC B1001 code.
- ✔ Unexplained battery drain, stalling, or misfire conditions.
- ✔ A cluster of diagnostic trouble codes (DTCs) related to body systems.
