An electric radiator fan should spin freely. if it doesn’t, chances are the bearings are worn and the fan must be replaced. faulty radiator fan relay(s) carmakers use many different relay configurations to achieve multiple radiator fan speeds. to make radiator fans run at low and high speeds, some carmakers use a series wired set of three relays.

If the outside air temperature is near or below freezing, the ecu will prevent the a c from running. and if the ecu isn't turning on the compressor, it will also not turn on the radiator fans. also, if the outside air is cold,with the a c off, the engine might dissipate enough heat through the block and radiator without the need for the fans.
