2002 explorer, 4 door, 4x2. I was washing the car today and all of a suddedn i heard the clicking like the hazzards are on. except is the the theft light flashing, I tried to start the car, the key would not do anything. I took off the neg. battery cable for more than 1/2 hr. placed it back on and still nothing. right when i connect the battery the clicking and theft flashing begins again. any suggestions.
