2011 Explorer Fuse Diagram: Exploring the Fuse Boxes
2011 Explorer Fuse Box Diagram: Find the correct fuse for the circuit
This 2011 Explorer Fuse Box Diagram article shows two fuse boxes. The power distribution box, also called the battery junction box, 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 Power distribution box is a new design for the 2011 model year. The fuse and relay layout is completely different from previous years.
The Passenger Compartment Fuse Box, also called the Smart Junction box, is located under the dash on the driver’s side.

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 2014 F150 throttle body relearn procedure.
2011 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 60 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

Tips to diagnose electrical issues on your 2009 Explorer
Headlight operation
Unlike in older models, the multifunction headlight switch does not switch power to the headlights. It is simply a request for headlights. The multifunction switch has a series of resistors that drop voltage as you turn the stalk. The smart junction box determines whether you’re requesting parking lights, headlights, or high-beam lights based on the voltage drop. The actual power switching of power from the headlight fuse to the headlights is done inside the smart junction box.
If your headlights aren’t working and the headlight fuses are good, the easiest way to diagnose the problem is to use a bidirectional scan too to view live data from the smart junction box. You will see that on the scan tool if it’s receiving the headlights ON request. However, if you’ve turned the stalk to headlights and the smart junction box isn’t seeing the request, then the problem is in the multifunction switch or the wiring from the MF switch to the SHB
If your power windows don’t work
• Power to the front windows is provided by the Accessory Delay Relay in the Smart Junction Boxon. Power then flows to Fuse #48 30A in the SJB. Power to the rear windows is controlled by a 30A circuit breaker in slot 48 of the SJB
If your blower motor doesn’t work
The blower motor gets its power from the blower motor relay #34 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.
