Ok so ive owned my 2003 Impreza rs for 2 years and the fan has always worked fine. I changed the theremostat and coolant sensor and the fan completely stopped working. Even when u turn on the ac the fan doesnt come on eithor. Checked fuzes and all the relays and they're fine . Can some one please help. I would really appreciate it thank u.

Hi.. Those fans only come on when your engine starts to get overly hot. It is winter where you are so they may never come on till next summer.. Even here where it was 42c (108F) yesterday and 32c today, the still fans aren't on all the time...

You probably didn't burp the system properly when you refilled it and there is trapped air blocking the coolant from circulating.

I burped it for like 30 min but ill try again. Would that be it or something else

Take the connectors loose to your fans, and connect a power probe to them,(make sure you connect the probe correctly or you could fry something), and see of the motors have gone bad. You could have new fuses, relays, and an entire new cooling system in the car(thermostat, radiator, heater core, radiator cap, water pump) everything. But if your fan motors are bad, they won't turn on.
