2014 F150 Fuse Box Diagram: Exploring the Fuse Boxes
2014 F150 Fuse Box Diagram: Find the correct fuse for the circuit you’re working on
In your 2014 Ford F150, you’ve got two fuse boxes to keep track of: the Battery Junction Box, which is also called the Power Distribution Box under the hood, and the Body Control Module (BCM)/Passenger Compartment Fuse Panel.
Let’s start with the one under the hood. Just pop it open and take a look near in the center of the engine compartment above the radiator. You’ll find the power distribution box there. It’s like the nerve center for your truck’s major systems—things like engine management, emissions, and ABS brakes are all controlled by the fuses in this box.
Now, for the second fuse box, crawl under the dash on the passenger side. It’s tucked away in the footwell. This one takes care of all the interior electrical stuff like the radio, power windows/locks, climate controls, and those handy courtesy lights. It’s essential to give both of these fuse boxes a once-over every so often to make sure none of the fuses are blown. If your electrical gadgets aren’t acting right, it might be a sign that something’s amiss with the fuses.

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 2012 Mustang throttle body relearn procedure.

The 2014 F150 fuse box diagram compared to later years
The 2014 F-150 fuse box diagram resembles the 2013 F-150 fuse box diagram. However, Ford made substantial changes to the 2015 F-150 fuse box.
If you’re working on a later model F150 Fuse Box, please refer to the updated diagram.
Tips to diagnose electrical issues on your 2014 F150
If your power windows don’t work
• In previous model years, Ford used a 30A circuit breaker to provide power to the windows. However, starting in the 2014 F150, they went back to using fuses for the front windows.
The fuse for the driver’s side power window is #1 30A in the BCM, and the #3 30A for the passenger side window. However, Ford still uses a 30A circuit breaker for the rear passenger and driver’s side windows and the power sliding rear window.
The circuit breaker is located in the BCM in slot 48.
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.
