Fan problem on nx

[Brent Barts]

Hi all-took a 400 mile road trip today in the nx and now the driver's side
radiator fan won't shut off after you turn the ignition off.  At first i
thought it was kinda cool: went into taco bell for lunch and some rice boys
pulled up and there it was making some cool noises.  But now the thing won't
shut off!
When i remove the key the fan kicks on.  It will shut off when you put the
key to the accessories position.
Anyone have any ideas?
Thanks
Brent
