My 2004 Nissan Sentra 1.8 L is @ 145,000 km and the cooling fans stopped working. I tested the fans, and they work, fuses are good. I tried swapping the relays, it didnt work. I'm thinking the ect sensor is bad. But unsure which sensor near the alterator is the engine coolant temp. Sensor? There is 2 close by very similar. Also into block. Could it be a ecm problem if its not the sensor?
ps the coolant guage still works fine AND the when I press the AC button it does nothing.
