* Underhood Fuse Box: Located under the hood, typically near the battery. This box contains higher-amperage fuses and relays protecting major electrical components.
* Passenger Compartment Fuse Panel: Located inside the vehicle, usually on the driver's side, often under the dashboard or in the instrument panel. This box contains lower-amperage fuses for interior lights, power windows, etc.
To find the exact location and a diagram of the fuses and their functions, you should:
1. Consult your owner's manual: This is the most reliable source. It will have diagrams showing the location of both fuse boxes and a legend identifying each fuse.
2. Look for a cover on the fuse boxes: The covers usually have diagrams printed on the inside.
3. Search online: A quick search for "1999 Ford Windstar fuse box diagram" will yield several results, including images of the fuse box layouts. Be sure to verify the year and model is correct as diagrams can vary slightly between years.
Remember to always turn off the ignition before working with fuses. If you're unsure about any fuse, it's best to consult a qualified mechanic.
