Checking and Replacing Fuses in Ford Mustang

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.

Caution!

  • 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.
  • Always disconnect the battery before servicing high current fuses.
  • To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.

Location of Fuse Boxes

Passenger Compartment Fuse Panel:
Ford Mustang (S550; 2018-2023): Passenger compartment fuse panel location

  1. The fuse panel is in the right-hand side of the passenger footwell behind a trim panel and plastic key code card.
  2. To remove the trim panel, lift it from the rear retaining hooks, while pulling it toward you and swinging it away from the side.
  3. To reach the fuse panel, first remove the key code card.
  4. After replacing a fuse, return the key code card to the original position.
  5. To reinstall the trim panel, lineup the tabs with the grooves on the panel, drop the panel back into place, and then push it shut to reinstall the trim panel.

Power Distribution Box:
The power distribution box is in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads. If you disconnect and reconnect the battery, you need to reset some features.
