The fuse box of a Mercedes B-Class is located under the front passenger mat, in a protected but easily accessible position. To reach it, start by moving any objects from the mat and remove it completely.

Once the mat is removed, you will find a panel or cover that protects the fuse housing. Carefully lift this cover using your hands or a thin tool, being careful not to damage the edges.

Inside you will find the fuse box with its clearly identifiable components. Before intervening, consult the vehicle manual to identify the fuse you want to check or replace and make sure you have a spare fuse of the same amperage.

After performing the intervention, carefully close the cover, reposition the mat, and check the correct operation of the electrical component in question.
