Anyone with any ideas what might cause my A/C fan (the one in front of the condenser just behind the radiator grille) to keep blowing for more than 45 mins after I remove the ignition key? I had to remove the A/C fan 30A fuse to stop draining the battery!

Its probably the sensor for the cooling fan that is mounted on the (if you stand in front of the car) left side. When the cooling fan goes try to unplugg tha cables to it and see if the fan stops.
