Radiator Fans on all the time when battery is connected, but when you start the car, the fans go off
Radiator fan stay on all the time when the battery is connected without the
motor running, we have to disconnect the negative terminal to keep the fans
from running the battery down. But when you start the car, the fans go off and
only work when the a/c is on or the temperature rises
I suspect you may have a bad fan relay or a bad temperature sensor on the coolant.
