Volvo S80 1 generation was produced in 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005 and 2006 in the TS body. During this time, the model was updated. In this publication, you will find a description of the fuses and relays of the Volvo s80 with block diagrams, photo examples of their design and location. Let’s highlight the cigarette lighter fuse.

The purpose of fuses and relays may differ from that shown and depends on the year of manufacture, region of delivery and the level of electrical equipment of your car.
