Moisture evaporates, thereby cooling off body heat
because cool air which comes from fan cool down our sweat
No.
Ther is usually a temp switch on your radiator that controls the fan. it is normally open when cool and closed at 220. if you want to test your fan you can pull the wires from the switch and put a wire acros the leads this powers the fan to on. if the fan powers on replace the faulty switch.
perhaps a defective fan switch. the fan switch detects when the coolant reaches a certain temperature, this temp is set by the car maker. the fan turns-on to cool the rad which is filled with VERY hot coolant. when the coolant reaches a more suitable temp the fan shuts off. one can hear the fan turn on and off if your sitting in the front 2 seats of a vehicle. as well you may be able to actually "feel" the fan turn on "through" the steering wheel, it would feel like a "slight" vibration. you would probably "only" feel this in an older used car.
The A/C does have an on/off switch. You are feeling the incoming air that is flowing through the vehicle whether the A/C is on or not. That is why it gets hot when you set the temp to hot. Set it to cool and turn the A/C off and you will feel the air temp of the incoming air whatever the outside temp is. Start the engine raise the hood, look at the compressor. If it is not turning it is off.
It is either the fan switch , fuse ,or the fan itself . Start by checking the fuses . Look in owners manual for fuse location . If the fuse is good have someone check the fan by wiring it direct to battery . If fan is good it has to be the fan switch . Some are in the radiator some are on the engine usually a round switch by the thermostat .
The radiators low fan switch turns on when the a car is standing still. Radiators cool off using the air around the vehicle. When a car is parked or at a light the fans turn on at intervals to keep the engine cool.
In order to cool a room with a ceiling fan, the fan blades should rotate counterclockwise to create a downdraft of cool air. This direction helps create a wind-chill effect, making you feel cooler without changing the room temperature.
It pulls the cool air from outside of the engine compartment through the radiator to cool the hot anti freeze for circulation though the engine block. The relay turns the fan on/off with a command from the thermal switch.
The fan does not have a switch - the thermostat switch runs the fan.
I am fighting the exact opposite problem on a 96 Mystique. I cant get my fan to come on and i have traced it back to be a ground problem. Wherever the switch is, it turns the fan on and off by closing the ground side of circuit, and activating the relay. Start by checking your relay, and making sure its not stuck "OPEN" otherwise, the switch, (Where ever it may be) is bad.
Depending on what type of fan, the fan control switch can be located on the wall for a ceiling fan. Each type of fan will have a different location for the fan control switch.
