2004 Ford Expedition Fuse Box Diagram: Locations and Fuse List
Your 2004 Ford Expedition has two fuse boxes. The passenger compartment panel is under the right side of the instrument panel, fuses 1 through 42.
The power distribution box is under the hood, fuses 101 through 118 plus fuse 401. The cigar lighter is fuse 41, rated 20A.

Ford renumbered several of these circuits inside the same body style, both before and after your model year. Skip to what changed by year if you want to confirm your truck matches this chart exactly.
Where are the fuse boxes on a 2004 Ford Expedition?
Recommended Best Deal Products
Passenger compartment fuse panel. Under the right side of the instrument panel, behind a PULL-tab cover. Place a finger behind the tab, pull it toward you, and swing the panel away to reach the fuses.
Power distribution box. Under the hood, in the engine compartment. It carries the high current circuits.
That means the starter relay, the ABS pump, the front blower motor and the air suspension compressor.
Worth knowing: my source does not state which side of the engine bay the power distribution box sits on. Your box cover label is the final authority here, and on any fuse this chart does not match.
Does a 2004 Expedition use the same fuses as a 2003 or a 2005 to 2006 Expedition?
No, not on every position. Your truck is the same generation, body style U222, built 2003 through 2006. Ford redesigned the Expedition again for 2007.
Ford renumbered eight circuits inside that single generation. Your 2004 truck sits in the middle of that change, not at either end.
Most published charts for this truck do not say that. I checked two of the largest aggregator sites, fuseandrelay.com and autogenius.info. Both publish one table under a page titled “2003 to 2006.”
Both match the 2005 to 2006 values, not your 2004 truck. A 2004 owner who trusts either chart gets the wrong amperage or circuit on five of these eight positions.
| Fuse | 2003 | 2004 (your truck) | 2005 to 2006 |
|---|---|---|---|
| 1 | 10A: wipers, cluster, TPMS | 10A: wipers, cluster, TPMS, same as 2003 | 7.5A: wipers, cluster. TPMS dropped from this fuse |
| 4 | 10A: DVD player, rear audio, CD changer | 15A: DVD player, rear audio, navigation radio | 15A: same as 2004 |
| 7 | 7.5A: radio | 7.5A: radio start signal, same as 2003 | 5A: radio start signal |
| 9 | 10A: alternator | Not used | Not used, same as 2004 |
| 12 | 10A: speed control servo and switch | 10A: speed control servo and relay, same as 2003 | 15A: fuel pump relay, shut-off switch, driver module, motor |
| 30 | 30A: body module door locks, liftgate glass release | 30A: same circuits as 2003 | 25A: air suspension module, 4×4 transfer case clutch |
| 33 | 20A: canister vent solenoid, HEGO sensors | 20A: same as 2003, adds IMTV and EVR solenoids | Not used |
| 34 | 20A: PCM, fuel injectors, idle air control, MAF sensor | 20A: adds fuel pump relay, shut-off switch and motor to the same fuse | 15A: PCM, fuel injectors, MAF sensor. Fuel pump dropped from this fuse |
Every other passenger panel position reads the same across all three years. So does every power distribution box position.

Which fuse protects the fuel pump on a 2004 Ford Expedition?
Recommended Best Deal Products
This is the number a generic “2003 to 2006” chart cannot give you. The circuit itself moved twice across this one generation. Your year sits at the point of the first move.
On a 2003 Expedition, the fuel pump relay is labeled R303. It lives inside the passenger compartment panel by relay name. It is not tied to one of the 42 numbered fuses in the public breakdown.
On your 2004 truck, fuse 34 is the one to pull. It is rated 20A. It now protects the fuel pump relay, the fuel pump shut-off switch and the fuel pump motor.
It still covers the PCM, the fuel injectors, the idle air control solenoid and the mass airflow sensor.
Ford changed this again for 2005. The fuel pump got its own dedicated fuse, 12, at 15A. Fuse 34 dropped back to 15A: PCM, injectors and the MAF sensor, fuel pump excluded.
If your fuel pump will not prime, check fuse 34 first on a 2004 truck. A 2003 owner should check relay R303 instead, and a 2005 or 2006 owner should check fuse 12. Three different answers to the same question, one per year.

How do you tell if a fuse is actually blown?
A blown fuse shows a broken metal strip inside the clear plastic body. Pull the fuse and hold it up to a light to check.
A hairline break is easy to miss. Test continuity with a multimeter set to ohms if the strip looks intact. Near zero resistance means the fuse is good.
Never guess the replacement rating. Match the number on the old fuse against your box cover label. A higher rated fuse lets the wiring become the fuse instead, and that failure costs far more to fix.
Why does the same fuse keep blowing?
A fuse that blows once is usually a one-off surge. One that blows again within days is telling you something is wrong upstream, not asking for a bigger fuse.
Unplug whatever you most recently added. A phone charger left in a power point is a common repeat offender. So is an aftermarket amplifier wired into the audio fuses.
Check for chafed insulation where the harness flexes, especially near the liftgate hinge and the driver door jamb.
If a fuse blows the instant you push it in, that circuit has a hard short. Stop replacing fuses and trace the wiring with a proper diagnostic tool instead of guessing. A plastic fuse puller keeps you from cracking the panel housing while you work through the circuit.
Does this chart apply to any other Expedition year?
Only 2003 through 2006. Ford built this body style, U222, for those four years only. The 2007 redesign brought a separate electrical architecture.
If you have a 2003 Expedition instead, most of this chart still applies. Four of the eight renumbered positions still match 2003. Four do not, including the fuel pump fuse.
Check the year comparison table above first, then see our 2003 Ford Expedition fuse box diagram for that year specifically.
If you have a 2007 Expedition or newer, that is the next generation. It carries its own fuse box and its own numbering. See our 2007 Ford Expedition fuse box diagram for that truck.
If you have a 2000 or 2001 Expedition instead, that is the earlier first generation body style. It also carries its own separate layout. See our 2001 Ford Expedition fuse box diagram for that generation.

Not sure your truck matches this exactly? Your box cover label is the final authority. That matters most on fuse 9 and fuse 34, the two positions that changed for your model year specifically.
Trailer tow, air suspension and third row seating are options that add fuses this guide covers. Your specific build may not use all of them.
