Ford F-150 13th Gen 2014-2020 Fuse Box Guide

ByAlex Smidt

The Ford F-150 thirteenth generation (2014–2020) uses multiple fuse and relay boxes to protect its extensive electrical systems. Understanding the exact location, amperage, and function of every fuse is essential for diagnosing electrical faults, replacing blown fuses correctly, and avoiding damage to sensitive electronics. This guide covers every fuse position in both the passenger compartment fuse box and the engine compartment power distribution box (PDB), along with the auxiliary relay box where applicable, for all variants including the 2.7L EcoBoost, 3.5L EcoBoost, 5.0L V8, and 3.3L V6 engines produced between 2014 and 2020.

Fuse Box Locations on the Ford F-150 (2014–2020)

The 13th generation F-150 has two primary fuse centers:

  • Passenger Compartment Fuse Panel – located on the driver’s side lower left of the instrument panel, behind a removable cover.
  • Engine Compartment Power Distribution Box (PDB) – located in the engine bay on the driver’s side, near the battery, under a snap-off cover labeled with a fuse diagram.

Important Fuse Ratings and Replacement Notes

  • Always use blade-type (ATO/ATC) fuses of the exact rated amperage – never substitute a higher-rated fuse.
  • Mega fuses (40A–60A) in the PDB require a flat-blade screwdriver to remove and must only be replaced with identical Ford-specification fuses.
  • The F-150 uses mini (APM), standard (ATO), and maxi (APX) fuse types depending on location – check the cover diagram before purchasing replacements.
  • A blown F32 (OBD-II port fuse) will prevent scan tool communication – always check this fuse first when a scanner shows no communication.
  • On 2017–2020 models with the 10R80 10-speed transmission, PDB F15 is especially critical – a blown fuse here triggers a no-start or transmission fault condition.
  • The BCM fuse (PDB F29, 50A) controls a wide range of comfort and safety features; replacement requires clearing fault codes with a scan tool after repair.
  • When adding aftermarket accessories to the auxiliary 12V circuits (F15, F16), total load must not exceed 20A per circuit.

How to Identify a Blown Fuse on the Ford F-150

  • Remove the fuse with the plastic fuse puller tool stored inside the passenger compartment fuse panel cover.
  • Inspect the metal strip inside the fuse body – a broken or melted bridge confirms it is blown.
  • Use a 12V test light or multimeter set to continuity/voltage to verify under-load conditions before replacing.
  • If a fuse blows repeatedly, do not replace with a higher amperage fuse – diagnose the underlying short circuit or overloaded component first.
