Too Afraid to Ask

A BCM is like the brain of a car’s electrical parts. It tells things like windows, locks, and lights what to do and keeps everything working together.

The Body Control Module (BCM) is an electronic control unit that manages various electrical functions in a vehicle, such as power windows, door locks, and interior lighting. It acts as the central hub for many of a car’s electronic systems.
