I have 2 fans on the radiator. One comes on when the AC is running. The other does not come on, even when the car gets hot. I know the sensor is giving me readings on the temperature gauge, and I have checked the relays by swapping them out. I have tested the fan motor by connecting it directly to the battery (it works fine)but the fan will not come on. Any suggestions?
