Ford Focus (1999 – 2007) Fuse Box Location and Diagrams
Ford Focus (1999–2007) fuse box locations and schematics are covered in this guide, which makes it simple to locate and use the appropriate fuses for electrical troubleshooting and repair.
Fuses and Relays
If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components
Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.
Changing a fuse
A fuse puller is located in the lid of the auxiliary fuse box.
Fuse Box Locations
Passenger Compartment
This is located on the left-hand side underneath the instrument panel.
Open the glove compartment. Push in both sides of the glove compartment and swivel it down completely.
Engine Compartment
This is located on the left-hand side of the engine compartment.
To check or replace a fuse, remove the cover of the fuse box by releasing the catch and lifting up.
