02 Ford Explorer Fuse Diagram: A Guide to Understanding Your Vehicle’s Electrical System

If you own an 02 Ford Explorer, it’s important to understand the different electrical components and how they work together. One of the most crucial parts of your vehicle’s electrical system is the fuse box. This article will provide you with a comprehensive guide to the 02 Ford Explorer fuse diagram, including what each fuse controls and where to find it.

What Is a Fuse?

A fuse is a safety device that protects your vehicle’s electrical system from damage caused by surges or short circuits. It’s essentially a small wire that’s designed to melt when too much current flows through it, thereby breaking the circuit and preventing damage to other electrical components.

Where Is the Fuse Box Located?

The fuse box in an 02 Ford Explorer is located under the hood on the driver’s side. It’s a rectangular box with a black cover that’s held in place by two clips. To access the fuses, you’ll need to remove the cover by pressing down on the clips and lifting it up.

How to Read the Fuse Diagram

The fuse diagram for an 02 Ford Explorer is printed on the inside of the cover of the fuse box. It shows the location and function of each fuse, as well as the amperage rating. The amperage rating is the maximum amount of current that the fuse can handle before it blows.

Understanding the Fuse Diagram

The 02 Ford Explorer fuse diagram is divided into several categories, each of which controls a different electrical component. These categories include:

1. Power Distribution Box

The power distribution box contains high-current fuses that protect your vehicle’s main electrical systems, including the alternator, starter motor, and battery. The fuses in this category are rated from 20 to 60 amps.

2. Fuse Panel

The fuse panel contains fuses that protect individual electrical components, such as the power windows, radio, and interior lights. The fuses in this category are rated from 5 to 30 amps.

3. Circuit Breakers

Some electrical components in your 02 Ford Explorer are protected by circuit breakers instead of fuses. Circuit breakers are designed to trip when too much current flows through them, just like a fuse. The circuit breakers in this category are rated from 15 to 30 amps.

4. Relays

Relays are electrical switches that are used to control high-current devices, such as the fuel pump and cooling fan. The relays in your 02 Ford Explorer are located in the power distribution box and are labeled with a diagram that shows their function.

Common Fuse Problems

If you’re experiencing electrical problems with your 02 Ford Explorer, it could be due to a blown fuse. Some common signs of a blown fuse include:

  • Electrical component not working
  • Fuse is visibly melted
  • Burning smell coming from the fuse box

If you suspect that a fuse is blown, you can check it using a multimeter or a fuse tester. If the fuse is indeed blown, you’ll need to replace it with a new one of the same amperage rating.


The 02 Ford Explorer fuse diagram is an important tool for understanding your vehicle’s electrical system. By knowing which fuse controls which component, you can quickly diagnose and fix electrical problems. Remember to always use the correct amperage rating for replacement fuses, and never replace a fuse with one that has a higher rating. With this knowledge, you can keep your 02 Ford Explorer running smoothly and reliably for years to come.
