did you ever fix this prob. i have a similar prob. accept mines does not shut off even when i shut the car off and key is out. i pull the relay and it shuts off. what sux is that i went to pepboys to get one and they don't even have n e thing that looks like it mines is black and green they only had a black one which still didn't fit and i even went to ford but of course they don't make it n e more, or so they say. let me know i'm curious to hear if replacing the relay fixed your problem.
