Where is the iod fuse in a 1999 Dodge Durango?

There's no standard "iod fuse" in a 1999 Dodge Durango, or in most modern vehicles. The term "IOD" isn't a standard fuse designation in automotive electrical systems. It's possible you're misremembering the term or there's a misunderstanding.

To find the fuse you're looking for, you need to know what circuit it protects (e.g., headlights, power windows, radio). The 1999 Dodge Durango has several fuse boxes: one under the hood and one inside the vehicle (often under the dashboard).

To find the correct fuse:

1. Consult your owner's manual: This is the best resource. It will have a fuse box diagram showing the location of each fuse and what circuit it protects.

2. Locate the fuse boxes: Find the under-hood and under-dash fuse boxes.

3. Identify the circuit: Figure out which electrical component isn't working.

4. Check the diagram: Use the diagram in your owner's manual to find the fuse that corresponds to the malfunctioning circuit.

If you can describe the circuit that's not working, I might be able to give more specific guidance. Otherwise, the owner's manual is crucial.
