Door Mirror : A fixed, hinged manual or power mirror located on an automobile’s door. The door mirror helps a driver see behind the vehicle. A power door mirror uses an electric motor(s) with a power window switch to help adjust the view of the mirror for the driver. A manual mirror uses cables to adjust the mirror. Door mirrors can be broken off the vehicle during minor accidents. Door mirror glass replacement may also be necessary if the mirror glass is broken. Some door mirrors must be painted to match the color of the vehicle.
