Most probably the radiator fan relay is stuck in the closed position resulting in power being constantly being supplied to the fan motor.

Check the radiator fan relay # 1 at junction box # 2, left front of engine compartment. give it some knocks to see if fan turns off. Remove the

It is the relay marked D in diagram. Try swapping with F to see if it stops. F is the EFI relay so it has to be reinstalled to prevent battery draining.
