    Buzzing noise in the lock area of my trunk when I lock the doors

    I'm not sure what is causing this problem, but I'm thinking it's the motor that is suppose to lock the trunk that is making this buzzing noise, but it's still locking so I'm a bit confused, cause if it wasn't locking I would think it's trying to work, but cannot, or maybe even though it's locking it's wearing out. So can someone help with this please, and does anyone know what is the name, make, model of that locking system for the trunk?

    Thx in adavance

    Sounds like the lock actuator is failing due to wear and age.

    It does sound like wearing out. It will also wear bat down as the noise is a battery draw
