How to Check the Inside of the Fuse Box on a Mercedes Benz W204

Model: Mercedes Classe C W204 - Years 2007-2013
Part: Fuse box

As shown in the video, this is a procedure that can be performed on any vehicle to check if the fuses inside their box, whether located in the cabin or outside, are functioning or blown. Open the fuse box. You will need to equip yourself with a 12-volt test light, the tip of which should be connected to the negative chassis ground. At this point, simply touch the tip of the test light to each fuse: if the light turns on, it means the fuse is working correctly; if it does not turn on, you will need to replace the fuse.
