I'm no expert at this, but I know you can run the aircon with the engine switched off, and also you can reprogramme the aircon.

Sounds to me like a switch sticking.

Someone with more knowledge should be along during the day.

I have noticed that sometimes mine does the same, sometimes, and had assumed that it was disapating any energy stored in the system. The fans will only stay on for 5 to 10 seconds though at most.
I presume that from what you are saying your fan will stay on forever, if you don't remove the fuse.

I assume you mean the internal blower motor.....if so then I suspect you also have climate control.....

In which case

1) Clear your scuttle drain out....
2) Replace the speed controller behind the passenger glove compartment, its got.had water in it.

Exactly the same as me.
As Mark said it's behind the glove box so this has to come out.
Then if you look up behind the dash you will see the fan casing, the controller is attached to the case.
It's not difficult, just fiddley.
