When you turn the fan speed down, it wont go any less than 6.
And when you push the off button, the fan keeps going.

Then when you turn off the car completely... Fans keep running.
Usually solved by flicking the ignition on and off.

I've tried pulling the unit out and checking over it, nothing appears odd.
Except when i put it back in the LCD screen is now very dark.

Any ideas guys ?

Thanks.

Problem solved.

It was the fan controller unit behind the glove box.
It backs onto an opening in one of the pipes which also can get leaves from the outside drawn into it.
The leaves get caught in the cooling fins of the controller unit and decompose with time and condensation from the air con, which made the alloy oxidise and one of the metal bits rust, causing it to malfunction.

Another one for the books, so to speak. :
