Unfortunately, without your specific owner's manual, pinpointing the exact fuse number is difficult. The manual will have a diagram of the PDC showing fuse locations and amperage.
Here's how to find the information:
1. Locate your owner's manual: This is the best resource. It will have a detailed fuse diagram specific to your vehicle.
2. Check online resources: Websites like the Dodge official site (though finding older manuals can be tricky), repair manuals (like Haynes or Chilton), or automotive forums might have the fuse box diagram. Search specifically for "1999 Dodge Durango SLT fuse box diagram." Pay close attention to match your exact trim level (SLT) as fuse layouts can vary slightly.
3. Look inside the underhood fuse box: The fuse box is usually located under the hood, often near the battery. The cover should have a diagram printed on it, though the print might be faded. Even if the diagram is unclear, you can try to identify the fuse by its amperage (usually printed on the fuse itself).
Important Note: Before working with any electrical components, disconnect the negative terminal of your battery to avoid short circuits.
