2005 Explorer Fuse Box Diagram: Find the correct fuse for the circuit
This 2005 Explorer Fuse Box Diagram article shows two fuse boxes. The power distribution box is also called the battery junction box and is located under the hood on the driver’s side near the firewall. It’s a rectangular box next to the brake master cylinder. The fuse and relays for the higher-powered devices are located in that fuse box.
The Passenger Compartment Fuse Box is also called the Central Junction Box. This fuse box is located at the end of the dash board on the driver’s side, covered by a trim panel. To access the fuse box, pull the trim panel toward the door.

Find the most commonly replaced fuses here
The fuse box diagram and table below show all 62 fuses and all the relays. But most DIYers are looking for fuses and relays for the lights, power ports, and the blower motor. I’ve listed the most commonly checked/replaced fuses here to save time. I’ve also listed the most commonly replaced bulbs. A blown fuse or bulb are the two most common reasons for lighting issues.

A note about fuses, battery power and keep alive memory
If you disconnect the battery or remove the PCM fuses from the fuse box, the PCM will lose its adaptive memory and baseline throttle body position. You can avoid this by providing backup power using a jumper pack and an inexpensive OBDII cable. See this article for more information on providing backup power to prevent the loss of adaptive memory. Or, you can perform a throttle body relearn procedure and then drive the vehicle so it can relearn the new adaptive memory settings. See this article for instructions on how to perform a 2005 Explorer throttle body relearn procedure.
2005 Explorer Fuse Box Diagram for Battery Junction Box/Power Distribution Box
The power distribution box is located in the engine compartment on the driver’s side. Find it near the firewall next to the master cylinder and wiper motor. The power distribution box contains high-current fuses that protect your vehicle’s main electrical systems from overloads.
How to find your fuse and the devices served by that fuse
There are 63 fuse/relay slots in the Battery Junction Box. The chart shows only 10 to speed up load time. Here’s how to find the fuse and circuit you want.
1) Change the number of entries showing (in the Show Entries Box) to 100 and scroll the list.
2) Enter the name of the component you’re searching for in the Search box.
3) Use the Next/Previous buttons at the bottom of the table

Explorer Fuse Box Diagram for Cabin/Passenger Compartment Fuse Panel
The cabin fuse panel is located on the far left-hand side of the instrument panel. Ford refers to this as the passenger compartment fuse box or the central junction box (CJB). The panel faces the driver’s door and is covered by a snap-in lid. Pull the panel cover outward to access the fuses.

Tips to diagnose electrical issues on your 2005 F150
If your power windows don’t work
If your power windows don’t work
The power windows are powered by a 30A circuit breaker, slot #47 in the underhood fuse box. Power then flows to the Accessory Delay Relay. From there it flows to master switch on the driver’s door.
The ADR relay is grounded by a microprocessor on the instrument cluster.
If your blower motor doesn’t work
The blower motor gets its power from the blower motor relay #3 in the battery junction/power distribution box.
If the circuit you’re working on contains a relay
• A simple way to test a relay is to swap in a similarly shaped relay and see if the component works.
• If that doesn’t work, remove the relay and test for power to the relay control coil and contacts using a multimeter. For more information on relay testing, see this article.
