The condenser fan blew out and damaged my radiator on a 2005 civic ex. The car is over heating and as the temperature needle goes up the radiator fan does not move. It only moves if I put the air on and press the AC button even though I have no AC because of the condenser fan being out. What do I need to check or replace, the radiator fan relay, the coolant temperature sensor, or the thermostat or all? Where exactly is the thermostat and the coolant temperature sensor located? Also, when the condenser fan blew out it got stuck inside and and came off from one of the holding screws and damaged the radiator and it has a small leak. Can the car function only with one fan? Do I need the condenser fan? The car is overheating just being parked and running....Please help!!!

The car has coolant. There is only a small leak where the condenser motor hit the radiator. Since the temperature gauge needle goes up and the cooling fan doesn't move (except when the ac air is on although it does not cool the engine), what can cause the cooling fan not to go on on its own? I replaced the coolant sensor switch that's by the upper radiator hose (motor side), and checked the relay in the fuse box and it works (I switched it with the horn relay and it does work). Do I need both fans for the car not to overheat? I though the other one was just for the a/c. By the way I also have not heat....please help The car has coolant.
