Do you mean the small OE fan that's hidden under the cowling? If so, is your A/C switch on?

Or, have you removed the aircon and all the pipework? Have you disconnected a connection from the aircon system?

I had this and wondered why the fan was on as soon as I started the car, even when it was cold. It was like Craig said, the A/C. It comes on with the air con. Turned it off and voila, the fan stopped :)

Thanks guys, found out the problem was supply voltage to the fan was running directly to the control power off wiper motor!!!!. WHO WOULD EVER DO THIS :mad:
