My windshield wipers (front) on a 2000 dodge grand caravan go off and on on their own. They wont work most of the time but they will just pop on on their own or if u turn the lights or high beams off and on. Sometimes they dont even have to have power they just come on. We have tried to replace the switch on the column checked the fuse box thouroughly and now we are baffled. Do u have any idea what it could be?

You can get free owners manuals online at:

http://www.edmunds.com/ownership/howto/articles/120189/article.html

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.
