Meant to suck air in through the radiator. If they are going the other way there's a wiring problem and you're likely to experience some cooling issues - if the car is still, they'd be feeding the radiator hot air and if it's moving they will attempt to blow the incomping air back. Not good for the cooling system and detrimental to thermofan life.
