I have an Australian delivered 2003 Outback 2.5L auto and the fan speed control is driving me insane, but as your forum suggests it is an inherent problem and can't be altered.
BTW have you guys checked out what they cost over here?
Have a look at www.redbook.com.au you will be surprised, I would be happy if ALL the local franchised Subaru dealers could do a good job and not return the vehicle dirty and covered on coolant.
