you know what it is

the stupid fan on the radiator just wont turn on
even when it gets hot while the car is running the fan will not turn on and cool the radiator

if i turn my heater on fullblast the temperature will go back down to normal.
if i turn my car off the fan will turn on and cool the radiator off


does anyone know why the radiator fan will not turn on while my car is running and it goes hott. i checked all my fuses and they all look good

i cant make sense out of this
