Connection between Climate CTRL and the Radiator Fan?


the cooling fan is designed to come on when the setting is in defrost or A/C mode . the a/c compressor is set up to come on in the winter to help keep the seals flexible by running and cooling fans run to help provide air across the condenser and radiator to cool engine water and makes a/c cold in summer time use . cooling fan will cycle as it reads data from related sensors. this is a normal condition with your car

Why does my fan keep running in my 2003 Volvo S 60 after the car is off?


It can be faulty fan relay.The relay is not turning the system off.Or its wire short issue.Even with ignition off ,the fan relay is getting power so its not letting the fan to turn off.Bypass the fan control relay and see if still the fan works with ignition off or not.

I have a 1991 MBZ 2.6 Liter. The front has two fans that are in front of the radiator...All of a sudden the fans are running, when the motor is running; Please tell me what the fans are for ,and why they...


The fans are radiator cooling fans. They are temperature controled so when you first start your engine in the morning they should not run - UNLESS you start it with your AC on. If you turn your AC on one of them should start operating and the other one will kick on when your engine starts getting hot.

Why there are 02 fans near radiator? What are the purposes? One is working and one is not.


Hi and welcome to FixYa I am Kelly.
You have 2 fans because one is the temperature controlled radiator fan that only runs when the engine water temp is above 160 deg. F. The water termperature controlled fan can run even with the ignition key OFF should the Engine water temp be too hot.
The 2nd fan is for your Air-Conditioner that should run when the cabin temp is set low enough for the Air-Conditioner compressor to run. This fan should run anytime the Air-Conditoner is switched on.
If your experiencing engine over heat problems when driving slow or sitting idle most likely the fan switch that is switched on by water temperature has failed. The fan switch controls a fan relay and if the relay fails the fan will not run. In this particular model there is a cooling fan module that controls the fan.

Fan cooling system of an engine v.w


A thermal switch controls the radiator fan and if the temperature of your radiator is above a preset temperature value, the thermal switch will close and the fan will turn on and will stay on even after you turn the motor off, until your radiator temperature cools down. I wouldn't worry about.
