Fuse Diagrams
This section presents comprehensive fuse box diagrams for the 2019 F250, providing detailed visual representations of the fuse locations and their corresponding functions.
These diagrams are essential for troubleshooting electrical issues, as they allow for quick identification of blown fuses and the specific circuits they protect.
Primary Fuse Box Diagram
The primary fuse box is located under the hood, near the battery. It contains fuses for critical vehicle systems, such as the engine control module, transmission control module, and power distribution module.
- Fuse 1 (10A): Engine Control Module
- Fuse 2 (15A): Transmission Control Module
- Fuse 3 (20A): Power Distribution Module
Secondary Fuse Box Diagram
The secondary fuse box is located inside the cabin, typically under the dashboard. It contains fuses for interior accessories, such as the radio, power windows, and climate control system.
- Fuse 1 (5A): Radio
- Fuse 2 (10A): Power Windows
- Fuse 3 (15A): Climate Control System
Fuse Functions
The fuse box in a 2019 F250 contains fuses that protect electrical circuits from overloads. Each fuse has a specific amperage rating, which determines the maximum amount of current it can safely handle. If the current flowing through a circuit exceeds the fuse’s rating, the fuse will blow, interrupting the circuit and preventing damage to the electrical components.
The following table lists all of the fuses in the 2019 F250 fuse boxes, along with their locations, amperage ratings, and functions.
Fuse Table
| Location | Fuse | Amperage | Function |
|---|---|---|---|
| Engine Compartment Fuse Box | F1 | 10A | Engine Control Module (ECM) |
| Engine Compartment Fuse Box | F2 | 20A | Fuel Injector Driver Module |
| Engine Compartment Fuse Box | F3 | 10A | Transmission Control Module (TCM) |
| Engine Compartment Fuse Box | F4 | 10A | Anti-lock Brake System (ABS) Module |
| Engine Compartment Fuse Box | F5 | 10A | Airbag Control Module |
| Engine Compartment Fuse Box | F6 | 10A | Horn |
| Engine Compartment Fuse Box | F7 | 10A | Headlights |
| Engine Compartment Fuse Box | F8 | 10A | Tail Lights |
| Engine Compartment Fuse Box | F9 | 10A | Turn Signals |
| Engine Compartment Fuse Box | F10 | 10A | Brake Lights |
Troubleshooting Fuse Issues
Identifying and troubleshooting blown fuses is crucial for maintaining proper electrical functioning in your 2019 F250. Understanding the symptoms, causes, and replacement techniques will help you effectively address these issues.
Symptoms of Blown Fuses
Blown fuses manifest through various symptoms, including:
– Malfunctioning electrical components (e.g., lights, power windows, audio system)
– Intermittent or complete loss of power to specific circuits
– Unusual electrical odors or burning smells
Causes of Fuse Failures
Fuse failures can result from several factors:
– Overcurrent: Excessive electrical current flowing through the fuse
– Short circuits: Direct connection between positive and negative wires
– Loose connections: Improper installation or corrosion leading to arcing and heat buildup
– Component failure: Internal malfunctions in electrical devices causing overcurrent
Replacing Blown Fuses, 2019 F250 Fuse Box Diagram
Replacing blown fuses involves the following steps:
1. Locate the fuse box: Refer to the fuse box diagrams provided in the previous section.
2. Identify the blown fuse: Use a fuse tester or visually inspect for a broken filament.
3. Remove the blown fuse: Use fuse pullers or pliers to gently remove the fuse.
4. Install the new fuse: Insert a new fuse of the correct amperage and type into the empty slot.
5. Check the circuit: Turn on the affected electrical component to verify the fuse replacement has resolved the issue.
Fuse Replacement Considerations
When replacing blown fuses in your 2019 F250, it is crucial to use the correct amperage fuses. Using fuses with an incorrect amperage rating can lead to serious electrical issues, including damage to electrical components or even electrical fires.
The amperage rating of a fuse indicates the maximum amount of current that can safely pass through it before it blows. If a fuse with too low an amperage rating is used, it will blow prematurely, potentially interrupting the operation of essential electrical components. Conversely, if a fuse with too high an amperage rating is used, it may not blow when it should, allowing excessive current to flow through the circuit, which can damage electrical components or cause an electrical fire.
Replacement fuses can be purchased at most auto parts stores or online retailers. When selecting replacement fuses, it is important to ensure that they are the correct amperage rating for the specific circuit they will be protecting. The amperage rating of each fuse is typically printed on the fuse itself or in the owner’s manual.

Frequently Asked Questions
Where are the fuse boxes located in the 2019 F250?
The primary fuse box is located under the hood, next to the battery. The secondary fuse box is located inside the cab, on the driver’s side, below the dashboard.
How do I identify a blown fuse?
A blown fuse will have a broken filament, which can be seen through the transparent window on the top of the fuse.
What amperage fuse should I use to replace a blown fuse?
Always use a fuse with the same amperage rating as the blown fuse. Using a fuse with a higher amperage rating can damage electrical components.
