Where is the fuse for the blower fan on a 2005 Mazda 3?

In a 2005 Mazda 3, the fuse for the blower fan is located in the fuse box under the dashboard on the driver's side. You'll need to remove the cover to access the fuses. Look for the fuse labeled "Blower" or "HVAC" in the diagram on the cover for identification. If the fuse is blown, replacing it should restore functionality to the blower fan.
