Where is the iod fuse in a 2003 dodge caravan?

There's no such thing as an "iod fuse" in a 2003 Dodge Caravan (or any other vehicle for that matter). There may be a misunderstanding or a typo.

To help you find the fuse you're looking for, please tell me:

* What circuit is the fuse for? (e.g., headlights, power windows, radio) Knowing the circuit's function will help narrow down the location and rating of the fuse.

* What is the actual wording you're seeing? (e.g., a label, a diagram) Sometimes similar-sounding words can cause confusion.

Once you provide this information, I can help you locate the correct fuse in your 2003 Dodge Caravan's fuse box(es). There's usually one under the hood and one inside the vehicle, often in the dashboard.
