Volvo XC90 Fuse Box Locations and Diagrams (2015-2025)

The second-generation Volvo XC90, including the Twin-Engine and Recharge Plug-in Hybrid versions, has been available from 2015 to 2025. Known for its elegant Scandinavian design, advanced safety technology, and luxurious interior, this generation marked a significant leap in Volvo’s approach to premium SUVs.

In this article, you will find fuse box diagrams for the Volvo XC90, covering model years 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024 and 2025. These diagrams are essential for identifying fuse panel locations and understanding the function of each fuse and relay, especially in hybrid and plug-in hybrid configurations.

What’s Included:

Fuse Box Diagrams – Detailed visuals for each model year showing the arrangement of fuses and relays.
Fuse Panel Locations – Instructions on where to find fuse panels in the vehicle (e.g., engine compartment, passenger compartment, cargo area).
Fuse Assignments – A complete breakdown of what each fuse and relay controls, helping you with diagnostics and maintenance.

Whether you’re replacing a fuse or diagnosing an electrical problem, this guide will assist you in maintaining the functionality and reliability of your Volvo XC90 (2015–2025).

Fuse Box Locations

1) Engine compartment

2) Glove compartment

3) Cargo compartment
