I would first check to see if there is freon in the system if not then you need to recharge and it should fix your fan problem if yes you might have a faulty A/C pressure sensor that could keep the fan running on high as the computer is not sure what's going on and keeps it running so it doesn't over heat. but even if there is freon it could still be very low so adding about half of small can will not do much harm to test it.
please post your results back once you have it fixed so other searching the forum will have info need to fix their vehicle
