Hello guys, I have a caliber crd 2.0 diesel, I realized that to be a bit 'of time I have the radiator fan always on. To be cold or hot engine it is. The car off also turns off her. What do you think it might be, I know that there is a liquid sensor but I did not understand if there is also a relay and where it is located. What do you recommend, tomorrow will replace the liquid sensor, I could also check?

 

it is more than likely located inside the PCM. I know they will run anytime the the a/c compressor is on, which is when the snowflake button is lit or if the control is set to floor/defrost or defrost and the blower is on.
