If you’re facing electrical issues or needing to replace a malfunctioning component, the fuse box located below the dashboard is the first place to check. This box houses several important circuits that power your car’s electrical systems. Identifying and understanding the layout of this box will help you troubleshoot problems effectively.
The fuse box contains fuses that protect key systems like the interior lights, radio, power windows, and more. These components can be affected by a blown fuse, causing them to stop functioning. Knowing which fuse controls which system can save you time and effort when diagnosing an issue.
To access the fuse panel, you’ll need to remove the cover located near the driver’s side footwell. Once the cover is off, you’ll find a clear labeling system that identifies each fuse. Refer to your vehicle’s manual or the label inside the cover for details on which fuse corresponds to each circuit.
1999 Ford Mustang Fuse Box Location and Layout

To begin troubleshooting electrical issues, locate the fuse box positioned beneath the dashboard near the driver’s side. The panel is mounted close to the footwell area, making it easily accessible for fuse replacement or inspection. To access the box, simply remove the cover, which should reveal a grid of fuses arranged by their corresponding systems.
The layout is designed for convenience, with a clear identification system for each fuse. Inside the cover, you’ll find a diagram that maps out which fuse controls each electrical component. Pay close attention to this chart, as it will be helpful for quick troubleshooting and replacement.
Common Systems Protected by the Fuse Box

The fuse box in this model protects several critical systems within the car. Common systems like the air conditioning, headlights, interior lighting, and power windows rely on specific fuses located within this panel. If any of these systems are malfunctioning, the first step is to check the fuse corresponding to the affected system.
For example, if the lights inside the cabin suddenly stop working, the fuse for the interior lighting is the likely culprit. Similarly, a non-functional radio or faulty power windows are often tied to blown fuses. By knowing the fuse layout and its corresponding systems, you can narrow down the problem area quickly.
How to Identify a Blown Fuse
When a fuse is blown, it can be identified visually. Most fuses will show a clear break in the metal filament inside. If the filament appears intact, the fuse is likely functional. It’s advisable to use a fuse puller or needle-nose pliers for safe removal, ensuring you avoid damaging the fuse panel or nearby components.
If you’re unsure about the fuse’s condition, it’s helpful to use a multimeter to test for continuity. A lack of continuity indicates that the fuse has blown and should be replaced. Always replace a blown fuse with one of the same amperage to prevent further damage to the electrical system.
How to Locate the Fuse Box in a 1999 Ford Mustang

The fuse panel is positioned on the driver’s side, just below the steering column. To access it, you’ll need to kneel or crouch in front of the footwell area. Look for a rectangular cover that hides the electrical components responsible for powering various systems within the vehicle.
Once you’ve located the panel, use your fingers or a flat tool to gently pry off the cover. Be careful not to damage the panel or the surrounding trim. The cover typically stays in place with clips that should release easily once pressure is applied.
The fuse box is mounted on the left side of the footwell area, directly beneath the dashboard. Inside, you’ll find rows of small, square connectors. Each connector is associated with specific electrical functions such as the interior lighting, power windows, or the climate control system.
- Locate the label on the inside of the panel cover. This will show you the mapping for each fuse, making it easier to identify the one responsible for the system you’re troubleshooting.
- If the label is not visible, check your vehicle’s owner manual. The exact location of the box and its components will be clearly listed in the manual’s electrical section.
After locating the correct fuse, you can proceed to test or replace it. Always ensure the replacement fuse matches the amperage listed in the diagram to avoid electrical damage.
