The wing mirror--more commonly referred to as a side mirror or a side-view mirror--on your Ford Focus is attached to the door, mounted in place on the inside part of your door panel. Fortunately, the Ford Focus has a separate mirror panel (called a sail panel) you can use to access the mirror. On some vehicles, complete door panel removal is required to replace the side mirror. The process of replacing the mirror is the same on all first-generation (2000 to 2007) Ford Focus vehicles, including the hatchback and the station wagon.
Disconnect your negative battery cable, if your Ford Focus has power side mirrors. If it has manual side mirrors, disconnecting the battery is unnecessary.
Pry off the wing mirror's inside sail panel (shaped like a triangle). Insert a trim panel tool between the door skin and the plastic panel to pry it off.
Carefully pull the sail panel away, minding the wiring if the mirror is power-operated. Unplug the electrical harness and set the panel aside.
Open the door and hold the outside part of the wing mirror steady. Remove the mounting bolt with a socket wrench, and then remove the mirror screw with a Phillips screwdriver (the mirror bolt and screw is visible with the panel removed).
Pull the wing mirror assembly from its mount (from the outside). Insert the replacement mirror assembly in place; tighten the bolt and the screw.
Attach the wiring connection to the replacement mirror. Position the sail panel in place and push it against the door to snap it back on.
