Disconnected the battery for an hour, reconnected and as you could of guessed.. fan came straight back on without the car even started.
I understand that after 2003 they changed they way that the radiator fan system works, and at some TLC services they are changing pre-2003 MCS's to the new system.
I still have my TLC book with 1 voucher left, is there any possiblity my local Mini Garage will fix/change the problem part?
Right, I had the same problem, ended up having to replace the fan unit completely .
Below are pictures of the part that cause's the problem. You can't buy this part separately, I believe it regulates the speed of the fan.... You can't see this part as its tucked away
I had the same problem - sharp tap in the centre of the fan cowl (by the above module) sorted it.
The dealer fitted a new assembly & told me the car was ready, when I got there it was in bits they said it didn't cure it. After another day they said the air con system had too much gas in it !!!! never heard of a car gaining gas over the course of a year
After unplugging the fan, follow the radiator accross to the left while looking at the fan. When you get the end of the fan, give a little tap with your fist to the radiator.
Thanks David......this worked a treat, there must be an underlying problem though.....shouldn't have to hit something to get it to work properly....for now it's a quick fix, so i THANK YOU very much.
I do have one qustion for you though.....how did you work out where to tap??

this happened to me once on the way to school, it was raining, and I ended up with a dead battery after 3hrs. I had to call the campus police to get a jump start. but that was the only time it happened to me. so I know, where is the plug to the radiator fan?

On an australian mini, plug for the fan is on the right hand side of the radiator as you look at the engine, it's a biggish plug just under/on the edge of the cowling.
That big green unit controles fan speed 2. You will also find a relay in there. The green thing is just a big resisitor. In the plug you will have a constant power (allows the fan to be opperated with the ignition is off) The other large wire is the switched wire from the fan control relay. The other smaller wire is the signal wire to activate the relay when the eng is switched on. The relay is a 87 and 87a type and commanly fails burning out and causing the fan to run constantly that is why hitting them turns them off. I will dig up a wiring digram for it as iv seen many minis with this problem.
