To avoid short circuits, damage to wiring and electrical equipment due to network overload, individual electrical circuits are protected by fuses with fusible links. Fuses of different ratings with so-called blade contacts are used. A blown fuse can be identified by a melted metal insert.
Before replacing a fuse, always switch off the corresponding consumer and the ignition.
Fuse box in the car interior
The fuse box is located on the driver's side and is covered by a pocket. The fuse assignment table is on the inside of the box cover (see illustration 23.0).
Removal
1. Disconnect the negative (-) battery terminal from the battery.
2. Remove the pocket on the driver's side that covers the fuse box.
3. Unscrew the bolts B securing the fuse box A (see illustration).
23.3. Unscrew the bolts B securing the fuse box A
4. Press the C tabs together and remove the fuse box from the instrument panel by disconnecting the connector on the back of the box (see illustration 23.3).
5. Cut the clamp 1 of the wire fastening, then press the clamps (see arrows in the illustration) and open the fuse box cover.
23.5. Cut the clamp 1 of the wire fastening, then press the clamps (see arrows) and open the fuse box cover
6. Remove the blown fuse using plastic tweezers.
7. Insert a new fuse rated for the same amperage as the blown fuse. The fuse rating is indicated on the back of the housing. In addition, the housing has a marking applied in paint, the color of which corresponds to a certain rating.
If the new fuse also burns out after a short period of time, the corresponding electrical circuit must be checked.
Never replace fuses with wire or other similar means, as this may cause serious damage to electrical equipment.
It is recommended to always carry a set of spare fuses of different ratings with you.
Installation
The fuse box is installed in the reverse order of removal.
