My 1999 Eddie Bauer Expedition acts like it's haunted when it rains. on 1999 Ford Expedition

The first time it happened, when I went outside in the morning the radio was on and would not go off even with no key. Other times the front blower would be on or the ding warning would go off with no key. I finally realized the connection with rain after a couple of dead batteries and now I have to cover the front of the car with a tarp so that something doesn't get wet any time it rains. Has anyone had a similar problem and is there a repair?
