Part: Fuse box

Inside the Mercedes Vito, model W639, there are two fuse boxes and one relay box. The first fuse box is located in the engine compartment, near the battery. The second fuse box is found under the driver's seat. The relay box is located inside the engine compartment, above the fuse box. Inside the relay box is the glow plug relay. If the glow plugs are not functioning, you will need to remove the relay and replace it with a working one. Since it is not possible to visually determine if the relay is burnt out, a diagnosis will be necessary.
