Trying to locate inside fuse box 2002 dodge grand caravan

It would appear that the relay is located on the cross rail that runs across the front of the vehicle (in front of the radiator). I found out that it is riveted in place by a single rivet, so in order to replace mine, I will have to remove the rivet and use a self-tapping screw to secure a new one.
The fan relay is located in the fuse panel located under the hood beside the battery. It will be marked under the lid. Make sure you check the maxi fuse for the fan also.

the cooling fan relay is not in the fuse box.

You can get free owners manuals online at:

or just type "owners manuals" in your search.

Here is a post I found that worked for my 2005 caravan.

For a 2001 Dodge Caravan: The owner's manual is vague, only stating that all fuses are under the hood in the fuse box, no diagrams. Once you have removed the fusebox cover, the diagrams for what each fuse does is provided under the lid. UNCLEARLY marked is the radio fuse, a 20amp fuse located 2nd row from top to the right of the accessory relay. It is marked: RDO/IP IGN.

The panel or the housing normally lists the names of the items that are controlled by the fuses. If that doesnt work, disconnect the battery terminals and you are good to go

The fuse box is located under the hood. There is component map printed on the inside of the cover. This tells you on your model where the fuse or relay is located
