Volvo S40 2nd generation was produced in 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012 and 2013. During this time, the model has been restyled. In this article you will find a description of the fuses and relays Volvo S40 with fuse box diagrams, their locations and photographs. Note the fuse responsible for the cigarette lighter.
The purpose of the fuses and relays may differ from the one shown and depends on the year of manufacture, the level of electrical equipment and the region where your car was delivered.
Passenger compartment
In the passenger compartment, the main fuse and relay box is located under the glove compartment, on the passenger side.
In order to access it you need:
- Remove the inner lining covering the fuse box by first sinking the center pin approx.
one cm in the mounting clip (1), and then remove the clip. - Remove the two wing screws (2) (holding the fuse box) by turning counterclockwise.
- Lower the fuse box (3) half way.
