2022 Volvo S90 Fuses
Fuses and central electrical units
Electrical functions and components are protected by a number of fuses in order to protect the car’s electrical system from damage by short circuiting or overloading. The fuses are fitted in the car’s various fuse boxes.
Warning
- Never replace a fuse with a foreign object or a fuse of higher amperage. This may lead to damage to the electrical system and cause fire.
- Contact an authorised Volvo workshop about replacing the fuses not described in the owner’s manual.
- If an electrical component or function does not work, it may be because the component’s fuse was overloaded, which must be changed. If the same fuse is overloaded repeatedly then there is a fault in the component. Volvo recommends contacting an authorised Volvo workshop for checking.
Location of central electrical units
The figure is schematic – appearance may vary depending on car model. Central electrical unit locations in a left-hand drive car – for a right-hand drive car, the central electrical units under the glovebox change sides.

Replacing a fuse
A fuse that has been overloaded needs to be changed in order to restore the function of the electrical component it is protecting.
- Locate the correct fuse in the fuse lists for the various fuse boxes.
- Pull out the fuse and check from the side to see whether the curved wire has blown.
- If this is the case, replace it with a new fuse of the same colour and amperage.
Some fuse boxes may contain special tweezers for a better grip on the fuse.
Never replace a fuse with a foreign object or a fuse of higher amperage. This may lead to damage to the electrical system and cause fire. Contact an authorised Volvo workshop about replacing the fuses not described in the owner’s manual.
Fuses under glovebox
The fuses in the fuse box under the glovebox protect components such as electrical sockets, displays and door modules.
The fuse box is located behind the floor mat/side panel. The fuse box in the engine compartment provides space for several spare fuses.
The positions of the fuses are shown on the inside of the cover. Functions and components in the fuse table cover several models and engine alternatives. A fuse description can therefore apply to fewer than those in the table, or be completely missing, depending on how the car is equipped. If a position has multiple table values, it is due to variations in equipment level. In which case, follow the value of the fuse being replaced. In the event of doubt – contact a workshop. An authorised Volvo workshop is recommended.

Fuses in cargo area
The fuse box with the cargo area fuses is located behind a panel on the right side.
- The central electrical unit is located behind the panel on the right-hand side.
- Special pliers are housed on the inside of the cover to facilitate replacement of tripped fuses
- The fuse box in the engine compartment provides space for several spare fuses.
The positions of the fuses are shown on the inside of the cover. Functions and components in the fuse table cover several models and engine alternatives. A fuse description can therefore apply to fewer than those in the table, or be completely missing, depending on how the car is equipped. If a position has multiple table values, it is due to variations in equipment level. In which case, follow the value of the fuse being replaced. In the event of doubt – contact a workshop.

- Special pliers are housed on the inside of the cover to facilitate replacement of tripped fuses.
- The fuse box also provides space for several spare fuses.
