Your car as 2 electric fans - they do not have slow or high speeds. They are either on or off.
the slow and high speeds only are applicable with
viscous clutch fan (land cruiser, cressida, crown, pajero, safari, Hino, UD, older mercedes benz etc)
electric fans with speed reducing circuits (corolla, sunny etc)
your cars thermoswitch is shorted with a wire - remove the short - and the fans will work automatically. The thermoswitch is the round 2 wire connector near the radiator pipe.
