* Owner's Manual: The most reliable source. Check the back of your owner's manual, it often has a fuse box diagram near the back.
* Inside the Fuse Box: There's usually a diagram printed on the inside of the fuse box lid itself. The Windstar likely has multiple fuse boxes (one under the hood and potentially one inside the vehicle).
* Online Repair Manuals: Websites like Chilton, Haynes, and AllDataDIY often have repair manuals including fuse box diagrams for a fee. These are detailed and often better than the in-vehicle diagrams.
* Ford's Website: While not always easy to find, Ford's website *might* have some information available. Searching their site for "1999 Windstar fuse diagram" may yield some results. However, this is less likely to be successful than the other options.
* Online Forums: Searching Ford Windstar forums (like those on sites like Ford-trucks.com or similar enthusiast sites) could turn up user-uploaded diagrams. However, always verify the information you find here with a more reliable source.
Remember to always disconnect the negative battery terminal before working with any fuses or electrical components in your vehicle.
