2019 F150 Fuse Box Diagram: Exploring the Fuse Boxes

2018 F150 Fuse Box Diagram: Find the correct fuse for the circuit you’re working on

This article includes 2019 F150 Fuse Box Diagrams and a full listing of all the fuses and relays in your vehicle. In your 2018 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 the hood and take a look near the firewall on the passenger side of the engine compartment. 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 driver’s 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.

BCM = Body Control Module under the dash. BJB = Battery Junction Box under the hood

The parking, stop, turn, backup, headlights, etc. are all powered through the body control module. There are no individual fuses for each light.
Blower Motor: Fuse #20 40A (BJB)
Horn: Fuse #1 25A (BJB)
Power Ports: Cigar lighter power point 1 Fuse #6 20 (BJB), Power point 2 Fuse #8 20A (BJB), Power Point 3 Fuse #51 20A (BJB), USB Smart Charger Fuse #58 5

How to find your fuse and the devices served by that fuse

There are 107 fuse 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

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 2017 F150 throttle body relearn procedure.

Tips to diagnose electrical issues on your 2017 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. In 2015, Ford switched to using Door Control Modules on the Driver and Passenger sides to operate the front windows.

The fuse for the driver’s side power window (Driver door control module) is #25 30A in the BCM, and the #26 30A for the passenger side window (Passenger Door control module. 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 for the rear windows is located in the BCM in slot 38.

If your blower motor doesn’t work
The blower motor gets its power from the blower motor relay #68 in the battery junction/power distribution box. The blower motor relay is powered by fuse #60 40A
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.
