During this time, the model was updated (restyling). In our material you will find a description of the fuses and relays of the Volvo S40 with block diagrams, their photos and locations. We will show the fuse responsible for the cigarette lighter.
The purpose of fuses and relays may differ from that shown and depends on the year of manufacture and the level of electrical equipment of your car.
Blocks in the cabin
Fuse and relay box
