Locations of the Fuse Boxes in the 2006 Ford F150
Passenger Side Fuse Box (Interior)
The primary interior fuse box is situated on the passenger side of the dashboard. To access it:
1. Open the passenger door.
2. Locate the small panel or cover on the side of the dashboard, near where it meets the door frame.
3. Pull the cover off to reveal the fuse panel.
This fuse box contains fuses related to interior electrical components, lighting, power windows, and other accessories.
Engine Compartment Fuse Box
The second major fuse box is located in the engine bay, typically on the driver's side or near the battery:
1. Open the hood.
2. Find the black plastic cover labeled “Fuse” or “Power Distribution Center.”
3. Remove the cover by unlatching or unscrewing it.
This box contains high-current fuses and relays responsible for engine management, cooling fans, and other critical systems.
Additional Fuse/Relay Boxes
Some models may feature supplementary fuse or relay boxes, such as under the rear seat or in the cargo area, depending on optional equipment and configurations.

Understanding Fuse and Relay Functions
Fuses and relays serve critical roles in protecting electrical circuits and enabling components to function:
- Fuses: Protect circuits from overcurrent by breaking the flow of electricity when a fault occurs. They are rated by amperage; using the correct fuse rating is vital to avoid damage.
- Relays: Act as switches controlled electrically to turn larger loads on or off, such as headlights or cooling fans. They are essential for managing high-current components safely.
Knowing which fuse or relay corresponds to each system helps in quick diagnosis and replacement.

Troubleshooting Common Electrical Issues Using the Fuse Diagram
When electrical components stop functioning, the first step is to check the relevant fuse or relay:
1. Locate the corresponding fuse in the diagram.
2. Remove the fuse carefully using fuse pullers or needle-nose pliers.
3. Inspect the fuse for a broken filament or discoloration indicating a blown fuse.
4. Replace with a fuse of the same amperage rating if necessary.
Common issues include:
- Blown interior lighting fuse causing lights not to work.
- Faulty engine control fuse leading to engine starting issues.
- Blown accessory fuses resulting in non-functioning power windows or seats.
If replacing a fuse repeatedly blows it again, further electrical diagnosis is needed, possibly indicating a short circuit or faulty component.
