2001 Expedition AWB Eddie Bauer, 5.4. After rain or a carwash the electrical system goes hay wire. Sometimes the lights, wipers, radio, AC go out. Sometimes I get multiple warning lights. Occasionally I get a no start situation. I've even had the headlights come on when the vehicle is off and parked. I'm trying to locate the body control module. I was told that is a classic problem and moisture will get inside. Anybody know where it might be located?
