In this article, you will find information about the fuses of the Ford Mustang (S550; models 2015, 2016, and 2017), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Ford Mustang
A fuse may fail if electrical components in the vehicle are not properly working. A broken wire inside the fuse indicates a failed fuse. Check the appropriate fuses before replacing any electrical components.
Caution!
- You must replace a failed fuse with one that has the specified amperage rating. If you use a fuse with a higher amperage rating, you may cause severe wire damage and may 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:
The fuse panel is in the right-hand side of the passenger footwell behind a trim panel and plastic key code card.
- To remove the trim panel, lift it from the rear retaining hooks, while pulling it toward you and swinging it away from the side.
- To reach the fuse panel, first remove the key code card.
- After replacing a fuse, return the key code card to the original position.
- 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 located 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 will need to reset some features.
