Locate the interior power block under the driver side dashboard and compare each labeled slot with the cover legend before removing any component. This avoids pulling the wrong protective element and prevents additional electrical issues.
The cabin unit typically handles low-amperage circuits such as interior lighting, audio system, and control modules, while a second distribution unit under the hood manages higher loads like cooling fans and braking systems. Each slot is marked with a number and function, often abbreviated.
Use a multimeter to confirm continuity instead of relying only on visual checks. A strip may appear intact but fail under load. Measure voltage on both sides of the slot while the circuit is active to verify proper operation.
Relays positioned рядом with the distribution unit control switching for components like headlights, horn, and fuel delivery. Swap identical relay units between circuits to isolate faults quickly.
Inspect wiring harnesses leading from the power block toward major components. Look for worn insulation, loose connectors, or heat damage near mounting points, as these issues often cause intermittent faults.

Check the driver side dash area first and match each slot with the printed legend on the cover to identify circuits like lighting, audio, and control modules before removing any protective element.
The interior distribution unit contains low-amperage links, while the engine compartment unit handles higher loads such as cooling fans and ABS. Each position is numbered and labeled, often with abbreviations, so verify amperage ratings before replacement and use a multimeter to confirm voltage presence on both sides of the slot during operation.
Exact location of interior and engine compartment fuse panels in 2010 Ford Fusion
Open the driver side lower dash cover to access the interior electrical distribution unit positioned beneath the steering column.
This cabin-mounted block sits behind a removable trim piece secured with clips or screws. Once removed, rows of protective inserts and relays become visible, each assigned to systems like lighting, radio, and control modules.
Use the legend printed on the back of the cover to identify each slot accurately, as labels are abbreviated and grouped by function.
For the engine compartment, lift the hood and locate the secondary power distribution unit near the battery on the driver side.
This unit is enclosed in a black plastic housing with a snap-on lid. Press the locking tabs to remove the cover and reveal high-amperage circuits and switching components responsible for cooling fans, ABS, and engine systems.
Check the inside of the cover for a printed layout showing circuit names and ratings before removing any component.
Ensure the housing is properly closed after inspection to protect internal contacts from moisture, dust, and heat exposure.
Inspect mounting points and wiring entry areas for looseness or wear, as vibration over time can affect connections and lead to intermittent electrical faults.
