Where is the fuse for a 2000 Mercury Sable defrost?

The fuse for the defrost system in a 2000 Mercury Sable is located in the fuse box under the dashboard on the driver's side. You can find the fuse box by removing the cover panel near the steering column. Refer to the fuse diagram on the cover or in the owner's manual to identify the specific fuse for the defrost system. If the fuse is blown, replacing it should restore functionality to the defrost.
