Quick Answer: Toyota Funcargo Fuse Box Locations
The Toyota Funcargo (1999–2005) has two main fuse boxes: an engine bay box near the battery and an interior box under the driver's side dashboard. Both covers carry a printed fuse diagram, and your owner's manual lists the exact ratings for your model year and engine.
Why Funcargo Fuses Deserve More Attention Than You Think
Few things stop a small MPV faster than a 15-amp fuse you can hold between two fingers. The Funcargo is a simple, reliable machine, but it is also a 20-plus-year-old vehicle now, and aging wiring, corroded grounds, and previous owners' aftermarket stereo installs all take their toll on the electrical system.
The fuses are the deliberate weak link in that system. They exist to burn out before a wiring harness does. When one fails, the symptom rarely points straight at the cause — a dead cigarette lighter might be a 15A blade fuse, but a no-crank condition could be a 120A maxi fuse bolted into the engine bay box and a charging fault behind it.
Safety warning first: before you touch any fuse, switch the ignition off and disconnect the negative battery terminal. On a car of this age the risk isn't just shock — it's a stray probe bridging a live circuit and turning a $2 fuse into a melted connector.
This guide walks through both fuse box locations, how to read the diagrams, typical amperage values, step-by-step testing, and the symptoms that send Funcargo owners searching in the first place. If you're also working through other electrical faults, our [link to related guide on similar topic] covers basic diagnostic workflow with a scan tool.
Toyota Funcargo Fuse Box Locations
There are two boxes you will actually use, plus occasionally a third relay block depending on the build.
Engine Compartment Fuse Box
Open the hood and look in the engine bay. In most Funcargo models the main fuse box sits close to the battery and the strut tower, on the same side of the bay as the battery.
What it looks like: a black plastic box roughly the size of a paperback book, with a snap-on lid marked "FUSE" or "FUSES." Some covers have a small arrow indicating the release tab.
How to open it:
- Press or pry the release tabs on the sides of the cover with your fingers or a flat plastic trim tool.
- Lift the lid straight up — don't yank it sideways, the plastic tabs on a 20-year-old cover get brittle.
- Look for the fuse puller clipped inside the lid. Toyota usually stows it there.
- Read the diagram printed on the underside of the cover before you remove anything.
What's inside: maxi fuses and larger main fuses for high-current circuits, plus several relays. These are the fuses that carry charging current, main power distribution, and ignition feeds. A blown ALT or MAIN fuse will leave you with a completely dead car, not just a dead radio.
One thing I've noticed working on these vehicles: variations exist between the 1.3L 2NZ-FE and 1.5L 1NZ-FE builds, and between early and late production years. Never assume the layout from a photo online matches the box under your hood.
Interior Cabin Fuse Box
The interior box handles the circuits you interact with daily — lights, windows, radio, cigarette lighter, wipers, and the blower motor.
Location: under the dashboard on the driver's side, generally behind a small removable panel near the steering column. On some builds it sits lower, in the kick panel area ahead of the door. Most Funcargo models are right-hand drive, so "driver's side" means the right side of the vehicle — if you're working on an export or converted car, check both sides before you start pulling panels.
How to access it:
- Turn off the ignition and remove the key.
- Locate the small rectangular cover labeled "FUSE" — usually removable by hand.
- If there's no obvious cover, look for a lower dash trim panel held by clips or a single screw.
- Pull the panel gently; plastic clips on older Toyotas snap easily in cold weather.
What's inside: standard blade fuses (ATO/ATC type), typically rated 5A to 30A. The diagram on the cover maps each fuse position to a circuit code.
Additional Fuse and Relay Boxes
Some Funcargo builds carry a secondary relay box in the engine bay near the battery or strut tower, and an instrument panel relay block behind the dash. How do you know if yours has one? Trace the main harness from the battery — if it splits toward a second enclosure before entering the firewall, you've found it. When in doubt, a factory wiring diagram is the only reliable answer, and we cover sourcing one in our [link to related guide on similar topic].
Fuse Box Location by Model Year (1999–2005)
| Production Years | Engine Options | Engine Bay Box | Interior Box | Notes |
|---|---|---|---|---|
| 1999–2001 | 1.3L 2NZ-FE / 1.5L 1NZ-FE | Near battery, driver's side of bay | Under driver's dash, near steering column | Early builds have fewer accessory fuses |
| 2002–2005 | 1.3L 2NZ-FE / 1.5L 1NZ-FE | Same general area | Same general area; some builds add a kick panel cover | Minor circuit additions; verify against your manual |
Toyota made running changes throughout the Funcargo's production run. Treat this table as a starting point, not a substitute for the diagram in your own car.
Toyota Funcargo Fuse Diagram Guide
How to Read the Fuse Diagram
Every fuse diagram gives you three things: a fuse number or code, an amperage rating, and the circuit it protects.
- Fuse number — the physical position in the box. Diagrams are drawn looking down at the box, so orientation matters.
- Amperage — printed in amps, and color-coded on the fuse body itself.
- Protected circuit — the code, such as ACC, GAUGE, or EFI.
Where do you find it? The lid of the fuse box is fastest. The owner's manual has the full listing. A Toyota service manual covers everything including relay logic and wire colors. Aftermarket online databases are convenient but often incomplete for a JDM-market model like the Funcargo — cross-check anything you find there against at least one other source.
Fuse color codes (standard blade fuses):
| Amps | Typical Color |
|---|---|
| 5A | Tan |
| 7.5A | Brown |
| 10A | Red |
| 15A | Blue |
| 20A | Yellow |
| 25A | Clear / White |
| 30A | Green |
Relays are not fuses. A fuse is a one-time sacrificial link; a relay is an electrically controlled switch that routes power to a load like the cooling fan or horn. You can test a fuse with a multimeter in seconds — a relay needs a coil test or a swap with a known-good unit.
Engine Compartment Fuse Diagram (Typical)
The values below are commonly cited for Funcargo-era Toyota fuse boxes. Use them as a reference only — ratings shift between years, engines, and trim levels.
| Fuse Code | Amps | Protected Circuit |
|---|---|---|
| ALT | 120A | Charging system / alternator output |
| MAIN | 60A | Main power distribution |
| AM1 | 50A | Ignition switch feed (accessory and start circuits) |
| AM2 | 30A | Ignition switch feed (second circuit) |
| EFI | 15A | Engine control unit, fuel injection, fuel pump relay |
| HORN | 10A | Horn |
| HEAD | 20A | Headlight circuit |
If the ALT fuse is blown, the charging system is dead and you're running on battery alone. These large fuses are often bolted in rather than clipped, so they need a socket, not a puller. Confirm the exact amperage on your own lid before replacing anything.
Interior Fuse Diagram (Typical)
| Fuse Code | Amps | Protected Circuit |
|---|---|---|
| GAUGE | 10A | Instrument cluster, warning lights |
| ACC | 15A | Accessory sockets, audio feed |
| CIG | 15A | Cigarette lighter / power outlet |
| WIPER | 20A | Windshield wiper motor |
| DEF | 20A | Rear window defogger |
| TAIL | 10A | Tail lights, license plate lamps, dash illumination |
A quick reality check: if your radio died but the dash lights work fine, you're probably looking at one 15A fuse, not a wiring fault. Start at the diagram, not the harness.
Relay Diagram
Common relays in a Funcargo include the EFI relay, horn relay, cooling fan relay, headlight relay, and turn signal relay. Most live in the engine bay box or a dedicated relay block nearby.
How to test a relay:
- Locate the relay using the diagram or the cover legend.
- Switch the ignition on and listen for an audible click when the circuit is triggered. No click usually means a dead coil.
- Pull the relay and check coil resistance across its control terminals with a multimeter. An open circuit (infinite resistance) confirms a failed coil.
- Swap it with an identical relay from a non-critical circuit — the horn relay is a handy donor — and see if the fault moves.
Common Symptoms of a Blown Fuse in a Toyota Funcargo
| Symptom | Likely Fuse Location | Typical Circuit to Check |
|---|---|---|
| Cranks but won't start | Engine bay | EFI, AM2 |
| Completely dead, no crank | Engine bay | ALT, MAIN, AM1 |
| Radio and cigarette lighter dead | Interior | ACC, CIG |
| Headlights or tail lights out | Engine bay / interior | HEAD, TAIL |
| Wipers won't move | Interior | WIPER |
| Blower motor dead | Interior / engine bay | Heater circuit, blower relay |
| Dash gauges and warning lights dead | Interior | GAUGE |
One pattern worth remembering: multiple unrelated accessories failing at once almost always points to a shared power or ground, not several fuses blowing independently.
Step-by-Step Troubleshooting: How to Check and Replace a Blown Fuse
- Gather your tools — a plastic fuse puller, a test light, a digital multimeter, a set of replacement blade fuses in mixed amperages, gloves, and safety glasses. Everything you need fits in a small pouch.
- Disconnect the negative battery terminal using a 10mm wrench. This isolates the system and prevents accidental shorts while you probe.
- Locate the correct fuse box — engine bay for main power and charging circuits, interior for accessories.
- Identify the suspect fuse using the diagram on the box cover or your owner's manual.
- Remove the fuse with the puller. Never use pliers — you'll crack the plastic body and leave fragments in the socket.
- Inspect the element visually. A blown fuse shows a broken metal strip or a dark, discolored window.
- Test with a multimeter set to continuity. Touch both blades; a good fuse reads near zero ohms. No reading means the fuse is open.
- Replace with a fuse of identical amperage. Same number, every time.
- Reconnect the battery and test the circuit. Turn the ignition on and operate the affected accessory. It should work immediately.
- If the new fuse blows right away, stop. You have a short circuit, a chafed wire, or a failing component. Chasing it with bigger fuses will damage the harness. This is the point to bring in a professional with a wiring diagram.
- Reset the ECU if needed. Disconnecting the battery for 10–15 minutes clears adaptive memory. On these cars, expect a rough idle for the first few minutes of driving while the ECU relearns fuel trim.
Tips for Maintaining Your Funcargo's Electrical System
- Keep a spare fuse kit in the glovebox. A mixed assortment costs very little and saves a tow.
- Don't overload circuits. Tapping a 15A accessory socket for a high-draw inverter is the fastest way to a repeat failure.
- Apply a thin film of dielectric grease to fuse contacts and relay terminals to slow corrosion.
- Clean and inspect grounds regularly. Loose grounds mimic blown fuses and are far more common on older vehicles.
- Check the fuse boxes for moisture after heavy rain or a car wash. Standing water in a fuse box causes corrosion and intermittent faults.
- Replace with the correct amperage only. A 20A fuse in a 10A slot doesn't fix anything — it just moves the failure point into your wiring.
Conclusion
The Funcargo keeps things simple: one fuse box in the engine bay near the battery, one under the driver's side dashboard, and a printed diagram on each cover. Match the fuse code to the circuit, test before you replace, and always use the same amperage.
The two rules that matter most: verify against your own owner's manual because ratings vary by year and engine, and never upsize a fuse to stop it from blowing. A $2 fuse is cheap. A burned harness is not.

Frequently Asked Questions (FAQ)
Where is the fuse box on a Toyota Funcargo?
There are two main fuse boxes. The engine compartment box sits in the engine bay near the battery, and the interior box is under the dashboard on the driver's side, usually behind a small removable panel near the steering column. Some builds also have a secondary relay box in the engine bay.
How do I know which fuse is blown?
Match the failed accessory to the circuit code on the fuse box diagram, then pull that fuse and inspect the element for a break or discoloration. Confirm with a multimeter set to continuity — a good fuse reads near zero ohms, and a blown fuse reads nothing. Visual inspection alone can miss a fuse that's cracked but still touching.
Can I use a higher amp fuse?
No. The fuse rating matches the wire gauge and the load it protects, so a higher-amp fuse lets more current flow than the wiring can handle. That overheats the harness, melts connectors, and can start an electrical fire. Always replace with the identical amperage.
Why does my fuse keep blowing?
A fuse that blows repeatedly is telling you there's a short circuit, a chafed wire, a failing component, or a water leak into the fuse box. Replacing the fuse without finding the cause just resets the clock. Inspect the circuit for damaged insulation and moisture intrusion, and if the fault persists, get a professional with a wiring diagram involved.
How do I reset the ECU after replacing a fuse?
Disconnect the negative battery terminal for 10 to 15 minutes, then reconnect it. This clears the ECU's adaptive memory. Expect a slightly rough idle for a few minutes on the first drive while the engine control unit relearns its fuel trim values — that's normal behavior, not a new fault.
