2001 Ford Expedition

I have a 2001 Ford Expedition every time that it rains, the car starts acting weird. In order to hear my radio I have to park my car. Once I turn to drive it turns off. One day I turned on the windshield wipers and the buzzing of the open door signal turned on. Once I take out the keys, most of the warning signs in the instrument panel turn on and off. I know this is an elecrtical problem because it only happens when it rains. Which component do you think is the most likely that I need to change or inspect. Thank you.
