Why does the cooling fan run all the time ?

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.

cooling fan not running.check for faulty cooling fan relay or fuse.cooling fan fan should be running when you turn on AC.hotwire cooling fan make sure cooling fan motor okay.

check your releyss
go to the salvage yard and buy a couple for 2 bucks each or a pocket full for free

sounds normal, the fans were made to run continuous w/ ac running, but on sensor when ac is off. if car isn't overheating, the fans are probably running from time to time ,but your just not catching them running

Need to look around and should have an error code and give more detail of what the problem is. If you post that i can maybe help you more. I need to know......

You might check the cooling fans on the condenser to see if they are running when the ac is on.If they are not check for blown fuse,or bad cooling fan relay.Do you notice if the ac cools better when running constantly,and the ac is not so cool when in traffic,stopping and going,and running slow?If so the cooling fan,or fans are not working.If the fan fuse and the relays check out fine,then replace the fan,or fans.If I can help any more please [email protected]

your AC cooling fan is not working properly, most vehicle has two fans, one for the radiator and another for AC, both work in sync with one another; if one cooling fan only working it does not produce enough cooling for both radiator and condenser at the same time; by running ac you producing more heat and its cant cool the engine fast enough with one fan so your engine is overheating when running AC. The temperature sensor could be faulty and need to be replace or your fan motor can also be faulty. Check the fuse first and the relay make sure they are not burn out. sensor cost about 30 bucks get it new, relay 35-40 new used 5 bucks at junk yard, fan get it from a junk yard for 25-30 bucks, new will run over 100 bucks. don't run the air and overheat your motor, it can damage your engine or may blow your radiator. if you do run ac watch the temp very closely, don't let temperature get into the red.

you mean it is not running, ok it will run the same time with the compressor, monitor if the compressor clutch engage while fan not ,check supply going to the fan if present. The fan is damaged and need to be repair.

Electric cooling fans do not run all the time. They will only come on if the engine exceeds normal operating temp. Also will run when AC is on. Easiest way to make sure they are operating properly is to first verify they run when the AC is on. Next turn the AC off and run the engine at 2500 rpms sitting still and monitor the temp gauge (don't let it get into the red). The fans should come on after 10-20 minutes (depending on outside temp.). As the engine cools down they will turn off.

I just had my coolant flushed and my radiator cooling fan replaced. The car was slightly overheating and would "gargle" in the coolant bowl after I turned the engine off. It turned out to be the radiator was clogged up on one side.

I went full tilt and replaced the radiator, water pump, thermostat, radiator cap and timing belt. I have 85,000 miles on the car and it was about time to do these things anyway. It is running like a new car now.
