WARNING: Always disconnect the battery before servicing high-current fuses.
WARNING: To reduce the risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.
- 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. See Changing the 12V Battery.
- Replace fuses with the same type and rating. See Changing a Fuse.

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 reinstall it, line up the tabs with the grooves on the panel, drop the panel back into place, and then push it shut.
- 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, line up the tabs with the grooves on the panel, drop the panel back into place and then push it shut to reinstall the trim panel.

CHANGING A FUSE
Fuses
WARNING: 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.
- 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.
Fuse Types
| Callout | Fuse Type |
| A | Micro 2 |
| B | Micro 3 |
| C | Maxi |
| D | Mini |
| E | M Case |
| F | J Case |
| G | J Case Low Profile |
FAQs
Fuses protect the electrical circuits in your Mustang by breaking the circuit if there’s an electrical overload or short circuit. This prevents damage to the vehicle’s electrical components and reduces the risk of fires.
The fuse box is typically located in the engine compartment, but there may be an additional fuse box inside the cabin.
A blown fuse can often be identified by a visible break in the wire inside the fuse. Additionally, the metal strip in the center of the fuse may be melted.
If a fuse blows, it’s essential to replace it with a new fuse of the same amperage rating. Using a fuse with a different rating can cause electrical problems or damage.
To check the fuses, you’ll need to remove the fuse box cover and visually inspect each fuse. If you suspect a fuse is blown, gently pull it out and examine it. A multimeter can also be used to check for continuity.
Yes, you can replace a blown fuse yourself if you’re comfortable doing so. However, it’s essential to follow proper procedures and use the correct replacement fuse. If you’re unsure or uncomfortable with the process, seek professional assistance.
Electrical issues such as non-functional power windows, lights, or the radio not working could be related to blown fuses. Checking the fuses is a common troubleshooting step for these problems.
Yes, it’s important to disconnect the vehicle’s battery before working with fuses to prevent electrical shocks or accidental circuit activation. Always use caution and follow safety guidelines.
Replacement fuses can typically be found at auto parts stores and hardware stores. Be sure to get fuses with the correct amperage rating.
