2018 Fusion Fuse Box Diagram: Exploring the Fuse Boxes
2018 Fusion Fuse Box Diagram: Find the correct fuse for the circuit you’re working on.
In your 2018 Ford F150, you’ve got two fuse boxes to keep track of: the Battery Junction Box/Power Distribution Box, located 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 look on the driver’s side of the compartment near the fender. 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, look under the dash on the driver’s side to the left of the steering wheel. Remove the trim cover over the fuse panel. 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.

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.

Tips to diagnose electrical issues on your 2018 Fusion
If your power windows don’t work
• The fuse for the driver’s side power window is #25 30A in the BCM, and the #26 30A for the passenger side window. The fuse for the rear driver’s door is #29 30A and rear passenger door #30 30A in the BCM.
If your blower motor doesn’t work
The blower motor gets its power from the blower motor fuse #79 40A in the 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.
