Locate the primary protection panel under the dashboard on the driver’s side and verify each slot against the factory labeling before replacing any blown element. The interior unit contains low-amperage circuits responsible for lighting, infotainment, and control modules, while the engine compartment housing manages high-load systems such as cooling fans and ABS. Misidentifying positions can lead to malfunction of unrelated systems.
The cabin-mounted distribution unit is secured behind a removable cover and organized in horizontal rows with clearly numbered positions. Each slot corresponds to a specific amperage rating, typically ranging from 5A to 30A, and must be replaced strictly with the same rating to prevent wiring damage. For example, climate control and audio circuits usually rely on mid-range ratings, while delicate electronics use lower values.
Under the hood, a secondary power distribution center is positioned near the battery. It includes larger protection links and relays that control ignition, fuel delivery, and drivetrain electronics. Before accessing this section, disconnect the negative battery terminal to eliminate the risk of short circuits or accidental activation of components.
Color coding plays a key role in quick identification: red typically indicates 10A, blue 15A, yellow 20A, and green 30A. Never rely solely on color; always confirm the stamped value on the top surface. Over time, previous replacements may not match original specifications, especially in used vehicles.
For precise orientation, consult the vehicle’s service manual where each slot is mapped with its function, including spare positions and relay assignments. Keeping a printed reference in the glove compartment simplifies roadside troubleshooting and reduces the risk of installing incorrect components.

Check the cabin power panel under the dashboard on the driver’s side first: remove the cover and read the slot numbering from left to right; positions F1–F5 handle interior lighting and control modules, while F6–F10 are tied to audio and climate control circuits. In the engine compartment, the relay and protection panel sits near the battery–slots labeled 1–8 typically manage ignition coils, fuel pump, and cooling fan; verify amperage values printed on each slot before replacing any element to avoid electrical faults.
The rear cargo-area panel, hidden behind a side trim cover, contains additional circuit protectors for rear electronics, including parking sensors and tailgate functions; numbering here usually starts from the top row downward, with mid-range slots assigned to lighting clusters and lower ones linked to accessory sockets. Always disconnect the battery before accessing these sections, and use a puller tool rather than pliers to prevent damage to contacts; mismatched ratings can lead to overheating or failure of onboard systems, especially in modules controlling stability and braking assistance.
Exact Location of All Fuse Boxes in the 2010 Volvo XC90 and How to Access Them
Open the engine compartment and go straight to the rectangular electrical panel positioned near the battery on the left side; release the plastic clips by pressing inward and lifting the cover upward to expose the primary power distribution area. This section contains high-amperage protection elements tied to critical systems such as cooling fans and ABS. Access requires no tools, but clearance improves if you slightly shift nearby wiring looms without disconnecting them.
The interior protection unit is hidden behind a trim panel at the end of the dashboard on the driver’s side; open the driver door fully, then pry off the side cover using a flat plastic tool to avoid scratches. Inside, you’ll find low- and medium-amperage elements responsible for cabin electronics, including audio, lighting, and control modules.
Rear Compartment Electrical Panel
Move to the cargo area and lift the floor panel; the rear electrical module sits along the left wall behind a removable cover. This section is less obvious and often missed, yet it protects circuits related to rear lighting, towing connections, and cargo accessories. To access:
- Fold back the cargo floor mat completely
- Remove the left-side panel by pulling its upper edge outward
- Locate the secondary panel secured with snap tabs
- Release tabs carefully to avoid breaking plastic mounts
Access Tips and Safety Steps
Before interacting with any electrical protection element, disconnect the negative battery terminal if working on high-load circuits under the hood. For interior and rear panels, ignition off is sufficient, but avoid pulling components while systems are active. Use a plastic puller tool stored in the main panel or a similar non-metal extractor.
Each panel has a label printed either on the inner side of the cover or adjacent to the slots; align numbers precisely when checking circuits, as positions vary slightly depending on trim level. Misidentifying slots can lead to unnecessary troubleshooting or disabling unrelated systems.
For tight areas, especially in the rear compartment, use a small flashlight and inspect orientation before removal. Reinstall each element firmly until seated; a loose connection can cause intermittent faults that are difficult to trace. Keep spare units of common ratings (5A, 10A, 15A) in the glove compartment for quick replacement.
