Fuse box diagrams can be found in the owner's manual. However, some diagrams are also printed on the back of the panel lid covering the actual fuse box.
Look up the "fuses" section in the owner's manual for the diagram and check the corresponding key that denotes which fuse controls which function. If the original owner's manual is unavailable, replacement manuals can be viewed and downloaded at owner.ford.com. Enter the year, make, and model to locate the correct manual.
The interior fuse box is located in a panel underneath the driver side or passenger side dashboard. Many websites provide assistance on how to locate the fuse box and change the fuses, including video tutorials.
