1. Inside the fuse box: The fuse box itself usually has a diagram printed on the inside of its cover. Open the cover carefully (it might be hinged or clipped) and look for a diagram showing the fuses and their corresponding circuits.
2. Owner's Manual: Your 1997 Ford Expedition's owner's manual should contain a detailed fuse diagram. This is often the clearer and more easily readable diagram.
If you don't have your owner's manual, you can often find a PDF version online through sites like Ford's official website (though finding one that old might be difficult), or through online automotive repair manuals (like Haynes or Chilton). Searching for "1997 Ford Expedition fuse diagram PDF" will likely turn up several results.
Remember to always disconnect the negative battery terminal before working with fuses to avoid electrical shocks or damage to your vehicle's electrical system.
