Radiator fan won't turn off - even when engine is off!

[mugs1979]

Discovered a flat battery this morning after car had been sat unused all weekend. When I jump-started it this evening, the radiator fan came on immediately which I thought was odd. I drove the car for 4ish miles (to attempt to charge the battery), and when I got out and put my foot to the pavement I noticed a lot of heat emanating from underneath the car.

To cut a long story short, the radiator fan seems to be stuck on, and will undoubtedly kil the battery again overnight (if it hasn't already...I'm ashamed to say I don't trust myself even to disconnect the battery).

Any ideas on what might be wrong? Is it something I can attempt myself? If not, how expensive might it end up being? I'm a 29-year-old girl who's a bit rubbish with cars but could probably enlist somebody a bit more mechanically-minded to help out if only we knew where to start!

Thanks in advance!

Thanks Myki. Any idea roughly how much it'll set me back if take it into my local friendly garage?

About £20 for the switch plus coolant plus what ever they charge for labour. Its easy to change yourself, its located half way down the right side of the radiator

Could be the fuse / fusebox melted.

Fusebox melted normally means no fans.

it could be that an earth is fubared or a short circuit.
