If it's your FSR the fan won't shut off usually. Even if you turn it off.
I would check the left rear where the NAV was to confirm you don't have the TCM. The PO might have left it in there. It's down low. A rectangular silver metal box with, I think, three wire plugged into it. Or you can pull the fuse for it. I can't remember the number. If you do have it, that will kill the power to it.
