That is normal. The fan is control by the coolant temperature. It will only run at a certain temp and then shut off when it cools below that set temp..

The cooling fans are supposed to run any time the a/c is on in order to keep air flowing across the condenser. Your a/c will not work properly at idle if they quit.
When the temp sensor fails, the computer will turn on the fan relay as a precaution to overheating. Once you find the problem with the sensor you may also fix the fan problem. If the check engine light is on you should also check the computer for trouble codes.
It seems you are low in coolant. The temperature sensor has air to sense instead of liquid and temperature gauge will be low. Try to fill up with coolant but sometimes it's hard to get rid of air from the system. Have you changed the engine thermostat?
Hope it helps
if its the cooling fan at the rad then your talking about then if you disconnect the plug on the fan and run jumper wires to it directly from the battery it should run.also check the plug connection to make sure its in good condition and no corrosion.if you jump the fan motor and it doesn`t run tap the motor it should run either way if it doesn`t then the cooling fan motor needs replacing.
REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.MAKE SURE COOLANT NOT LOW.IF ALL IS GOOD CHECK FOR LEAKING WATER PUMP WEEP HOLE IF LEAKING REPLACE WATER PUMP.MAKE SURE COOLING FANS RUNNING.IF ENGINE RUNNING HOT WHILE SITTING LONG TRAFFIC LINE AND COOLANT NOT RUNNING.CHECK COOLANT FAN RELAYS AND FUSE.IF ALL IS GOOD HOT WIRE MAKE SURE COOLING FAN MOTOR GOOD IF COOLING FAN DONT RUN WHEN HOT WIRED FAN MOTOR BAD.IF FAN MOTOR OKAY AND FUSE RELAYS GOOD YOU HAVE FAULTY COOLING FAN WIRING.YOU COULD HAVE BAD ENGINE COOLANT SENSOR OR FAULT IN ECM CODE SCAN TO CHECK THEM BOTH.CHECK ENGINE OIL.LOOK LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF OIL LOOKS OKAY.YOUR ENGINE BLOCK, RADIATOR AND HEATER CORE NEED FLUSHING.
You are talking about the thermo electric cooling fan, its operation
is independent of the car's electical system. It is switched on and off
by the engine temperature. When you park, the engine heat soaks upward
to heat the thermostat turning the fan on. It will run until the engine
cools down and the thermostat switches it off. Quite normal operation.
Do you mean it will run all night if you let it? The cooling fan can run for quite some time after the car is off and it is normal for it to behave that way, but if it runs all night.....sounds like you need to replace temperature sensor and/or switch.
