Any of you guys out there notice when you use your AC, the fan should work also right? (OK i don't use AC when its winter ok, just for defroser) because my volvo it doesn't work...but it worked on summer. I don't know if there's any sensor? or its just the weather is so cold and the engine its not that too hot....and also when I drive atleast 45mins it still doesn't work, ut not overheating (temperature is normal). I checked all the fuses and all the relays everything works fine. any idea why my fan is not working?

 

Fan might be bad.
