2017 Ford F-250 Super Duty Fuse Box Diagram & Amperage

Quick Answer

The 2017 Ford F-250 Super Duty has multiple fuse boxes located in the following areas:

• Under-hood Fuse Box: Located in the engine compartment, typically near the battery on the driver's side.
• Passenger Compartment Fuse Box: Found behind the kick panel on the passenger side of the dashboard.

Under-hood Fuse Box (Power Distribution Box)

This fuse box is located in the engine compartment, usually near the battery. It contains high-current fuses and relays for major electrical components.

Common Relays: Starter Relay, Fuel Pump Relay, PCM Relay, Cooling Fan Relays, A/C Clutch Relay.

Note: Fuse configurations can vary slightly due to trim levels and optional equipment. Always refer to the fuse legend printed on the inside of your fuse box lid for the most accurate information.

Passenger Compartment Fuse Box

This fuse box is located behind the kick panel on the passenger's side of the dashboard. It typically handles power for interior accessories and lighter loads.

Note: Fuse configurations can vary slightly due to trim levels and optional equipment. Always refer to the fuse legend printed on the inside of your fuse box lid for the most accurate information.

How to Test a Fuse

Testing a fuse is a straightforward process that requires a fuse puller (often found in the fuse box lid) and a multimeter or a fuse tester. Always ensure the ignition is off before working with fuses.

1. Locate the Suspect Fuse: Identify the fuse associated with the malfunctioning component using the diagrams above and your vehicle's fuse box legend.
2. Visually Inspect: Many fuses are transparent, allowing for a visual check. Look for a broken wire or a melted appearance inside the fuse. If it's dark or melted, it likely needs replacement.
3. Use a Fuse Tester (Indicator Style): Insert the probes of a fuse tester into the small test points on the top of the fuse. If the light on the tester illuminates, the fuse is good. If it doesn't light up, the fuse is blown.
4. Use a Multimeter: Set your multimeter to the continuity or ohms setting. Remove the fuse from its slot. Touch one probe to each metal blade of the fuse. A good fuse will show a reading close to zero ohms (continuity). If there's no reading or "OL" (open loop), the fuse is blown.
5. Replace with Correct Amperage: If a fuse is blown, replace it with a new fuse of the exact same amperage rating and type. Using a higher amperage fuse can cause serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more common than others due to the frequent use or power demands of their circuits. On a 2017 Ford F-250 Super Duty, you might frequently encounter issues with:

• Cigar Lighter / 12V Power Outlets (Passenger Compartment Fuse Box, F2): These fuses are often blown due to overloads from charging multiple devices or using high-power accessories. Always check for frayed cords or faulty devices plugged into the outlets first.
• Trailer Brake Control Module (Under-hood Fuse Box, F3): Heavy towing can sometimes put a strain on this circuit, leading to a blown fuse. Inspect your trailer wiring for shorts or damage if this fuse repeatedly blows.
• Blower Motor (Under-hood Fuse Box, F7/F23): A failing blower motor or a restricted cabin air filter can cause the blower motor to draw excessive current, blowing the fuse. Check for obstructions in the blower motor housing if your fan isn't working.
• Headlights (Under-hood Fuse Box, F9, F10, F11, F12): A burnt-out bulb doesn't usually blow a fuse, but a short in the wiring or a faulty headlight assembly can. If only one headlight is out, it's likely the bulb. If both are out, check the respective fuses.
• Radio/Infotainment System (Passenger Compartment Fuse Box, F1): Issues with aftermarket installations or internal component failures can sometimes lead to this fuse blowing. If your radio is completely dead, check this fuse.

Always address the underlying cause of a blown fuse before replacing it, otherwise, the new fuse will likely blow again.
