To tell if a fuse is blown without a multimeter: Visually inspect the fuse by removing it from its holder and looking through the transparent body. A blown fuse usually has a broken or melted wire inside and may show scorch marks or dark spots. Alternatively, you can use another identical, working fuse from your fuse box and see if it solves the issue. Always ensure the power is off before handling fuses to avoid any safety risks.
