Electrical functions and components on your 2022 Volvo S90 are protected by a number of fuses in order to protect the vehicle’s electrical system from damage by short circuiting or overloading. Fuses are located in the vehicle’s fuse boxes. These fuse boxes are located under the hood on the right side of the engine, under the dashboard on the passenger side, and on the passenger side of the trunk.

Fuse Replacement Precautions
An overloaded fuse needs to be replaced to restore function to the electrical component it protects.
Locate the correct fuse in the fuse diagrams for the different fuse boxes.
Details for mileage, safety, and performance.
Pull out the fuse and examine it from the side to determine if the curved metal wire in the fuse is intact.
If the wire is broken, replace the fuse with a new fuse of the same color and amperage.
Note
Some fuse boxes contain special pliers to make it easier to grip the fuse.
Warning
Never use a foreign object or a fuse with a higher amperage than that specified to replace a fuse. This could cause significant damage to the electrical system and possibly lead to a fire.
Warning
Contact an authorized Volvo workshop for assistance replacing fuses not listed in the Owner’s Manual. If fuse replacement is performed incorrectly, significant damage can be caused to the electrical system.
