Quick Answer
The 2015 Ford Transit has multiple fuse box locations to manage its electrical systems:
- Under-hood Fuse Box: Located in the engine bay, typically near the battery or passenger side strut tower.
- Passenger Compartment Fuse Box: Found behind a panel on the passenger side kick panel or dashboard side.
Under-hood Fuse Box
This fuse box contains fuses and relays for critical engine functions, cooling systems, and major electrical components. Always consult the fuse diagram printed on the inside of the fuse box lid for the most accurate information applicable to your specific vehicle trim.

How to Test a Fuse
Testing a fuse is a straightforward process:
- Locate the fuse box: Identify the correct fuse box for the circuit you're troubleshooting.
- Identify the suspected fuse: Use the fuse box diagram (from your owner's manual or the lid) to find the fuse for the non-working component.
- Visual inspection: Many fuses have a small wire inside that will be visibly broken if the fuse is blown. However, not all blown fuses are visually obvious.
- Use a fuse tester or multimeter:
- Fuse Tester: A simple tool that lights up if the fuse is good when touched to both test points on top of the fuse.
- Multimeter: Set your multimeter to the continuity setting. Touch the probes to the metal test points on top of the fuse. A good fuse will show continuity (a beep or a reading close to zero ohms). No continuity means the fuse is blown.
- Replace if necessary: If the fuse is blown, replace it with a new fuse of the exact same amperage rating (e.g., replace a 15A fuse with a 15A fuse). Never use a fuse with a higher amperage rating, as this can lead to serious electrical damage or fire.
Common Blown Fuses on This Vehicle
While any fuse can blow, some circuits are more prone to issues due to their load or frequent use:
- Cigar Lighter/12V Power Outlets (F22, F23): These fuses commonly blow due to overcurrent from charging multiple devices, using high-power accessories, or short circuits from foreign objects inserted into the outlet. If you experience a non-working 12V outlet, check these fuses first.
- Radio/Infotainment System (F20): While less common, issues with aftermarket installations or electrical shorts within the entertainment system can sometimes cause this fuse to blow. If your radio suddenly stops working, this is a good place to start troubleshooting.
- Blower Motor (F13): A failing blower motor or obstructions in the hvac system can cause the blower motor to draw excessive current, leading to a blown fuse. If your HVAC fan isn't working on any speed, check this fuse.
Important Note: If a fuse blows repeatedly, there is an underlying electrical problem that needs to be addressed. Simply replacing the fuse without resolving the root cause can lead to further damage to your vehicle's electrical system.

Before you pull a fuse on the 2015 Ford Transit
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
