I change the fan and the temp sensor still nothing


When i turn the a.c on than they both turn on


The fans automatically come on when AC is on. Otherwise the temp sensor should turn the fans on when the engine heats up. You installed a new temp sensor but the fans are still not turning on - you may have a problem with coolant flow, like a blocked/plugged radiator, corroded water jacket in the engine, or a bad water pump. You can also replace the thermostat and radiator cap just to eliminate those possibilities.


Thank u i will try that
