The 2022 Ford Expedition IV, after the fourth-generation facelift, uses two main 12-volt fuse panels: the under-hood power distribution box and the Body Control Module fuse box in the passenger compartment. The 2022 electrical layout differs in several areas from the earlier 2018 Ford Expedition, so fuse numbers should not be carried over between model years without checking the correct table.
The tables below cover the circuits most owners look for first, including the five power points, USB chargers, 4×4 system, electronic limited-slip differential, power running boards, driver-assistance systems, trailer circuits and multi-contour seats. The assignments follow the 2022 Expedition owner information for the North American model; equipment can vary by vehicle and market.
Where are the fuse boxes in a 2022 Ford Expedition?
Under-hood fuse box: the power distribution box is located high in the rear area of the engine compartment, close to the cowl, under a large black cover. Release the cover latch to access the fuses. Ford warns that the 12 V battery should be disconnected before servicing high-current fuses.
Body Control Module fuse box: this panel is in the front passenger footwell, low under the glove box and behind the side trim panel by the door. This panel protects, among other systems, SYNC, the audio system, wireless charging, drive-mode controls, 4×4 controls and the heated steering wheel.

The 2022 model belongs to the same fourth-generation Expedition family as the 2018 version, but the fuse assignments are not interchangeable. Use the year-specific table when diagnosing a circuit rather than relying on the layout from another model year.

FAQ – 2022 Ford Expedition fuses
What should I check if the power running boards do not deploy?
The main fuse for the power running boards is fuse 40 – 40 A in the under-hood box. If it is intact, check the running-board module, door-status inputs and the mechanical drive.
Why can one 12 V power point fail while the others still work?
The Expedition uses separate protection for its power points. Fuses 32, 33, 34, 35 and 45 protect different outlets, so a fault in one circuit does not necessarily affect the others.
What should I check if the connected camera and some driver-assistance functions stop working?
Fuse 137 – 20 A in the under-hood box is one of the first circuits to inspect. It supplies the advanced driver-assistance systems module and the connected camera.
Why can drive-mode and 4×4 problems appear at the same time?
BCM fuse 31 – 10 A supplies the rear climate control module, drive-mode switch module, Terrain Management switch, radio-frequency transceiver and 4×4 switch. If several of these functions fail together, this circuit is a useful starting point.
Can I use the 2018 Expedition fuse chart for a 2022 model?
No. Both vehicles belong to the same generation, but the 2022 facelift brought equipment and electrical-assignment changes. Use the fuse chart for the correct model year.
