2001 Crown Vic electrical trouble, Power seats, locks, trunk, & fuel door died

My 2001 Crown Victoria has amazed me with its durability and since fixing a few things when I bought it has been trouble free except for this. My Power seats, Locks, Trunk release and fuel door all died at the same time. I've checked all the fuses, wiring where it constantly bends from opening and closing the door and everything else I could think of and nothing. I assumed it would be a common enough problem but spent many hours searching online and haven't found the same problem or anyones solution that would fix it. My Daughter recently got her permit and I'de like her to learn on this car and maybe let her have it as a first car, the trouble is the driver seat is in the Homey position and she's 5' 3"

Did you check the relay box under the hood by the drivers side fender ?

I'm sorry about all the posts, I kept getting "internal server error message code 500"

I may not have, can you tell me what I'm looking for?

I was at a junk yard earlier and took and changed all the relays, fuses & circuit breakers and still nothing? I changed a few on the other side too. The 3 on the drivers side were attached to a box? I'm not sure what that box does?

Can anyone offer their opinion on what the box is and or what the problem could be and hopefully tell me its a 99cent fix that takes less than two minutes start to finish? Has anyone else ever heard these or similar problems?
