The cooling fan is electric and the sensor reads that your car is hot. It stays on, even when the car is off so that it can cool your engine to acceptable temperatures. If it didn't, and the car remains too hot, it can warp parts and destroy your engine.

If the fan runs for an exceptionally long time, and drains your battery giving you a no start or weak battery slow start condition, you may have a bad cooling fan relay.

Why the cooling fans stay on when you turn your car on?

unless there is something wrong with your car, the cooling fans are activated when a sensor in the cooling system detects that the coolant is too hot and that is when the fans turn on to help bring airflow to the radiator or just to circulate hot air away from the engine. if the coolant is still hot when your car turns on, then the fan will stay on as well. Also, if the AC is in the on position both the fans will run.

1996 dodge grand caravan The cooling fan nor the ac fan turns on they spin freely but no action How can you troubleshoot this?

Perhaps there is no problem at all with your car's cooling system! The fan(s) you observe are controlled electrically by a second engine thermostat which will turn the fan on only to support cooloing when there is little forward motion of the vehicle. The fan(s)are designed to turn freely in the rushing wind and will only turn on when your car slows and needs "wind" to continue the cooling.
