The fan should work off of the water temp. The fan will come on and off to keep the constant temp on the cooling water. If equipped with a second fan it is probably for the AC and will run when the A/C is on. If you think the fan should be on. Then If you know where the fan relay is check to see if it is hot, if real hot the relay may be going bad. Hope you know this when you turn the car off the fan can still come on if the water temp is to high. My thought fan going bad, temp sensor or relay may be the problem.. If you can touch the fan motor metal housing and it is real hot the fan man be going bad, remember the blades can start at any time.
it depends on the kind of wiring system....but most cars ...the fan wil always start anytime the AC is switch ON.... and some cars the fan works with the thermostart
sounds like the fan solenoid is stuck. or keep in mind when defroster is on or any climate control in this car the ac compressor will run .wich in turn will kick on the electrick fan .try it with the climate control completely off. let me know
Usually a bad water pump will cause the engine to run hot with or without the ac being involved. The most common cause of overheating with the ac on is not enough air flow thru the radiator.
What you are most likely hearing is the compressor kicking on/off. The constant kicking could be a sign that there's insufficient refrigerant to keep the compressor running continuously without shutting on/off. Eventually, the compressor won't kick on at all, a safety feature designed to prevent doing damage to a compressor that's undercharged. Have the AC system checked.
only one is suppose to work the other kicks on when you turn ac on turn ac on does it come on now let me no and i can help you more from there check water level do you have the correct amount of water in resevior of car when car heats up half way fan kicks few minutes later fan should kick off with ac off of course sticking thermostat can cause car to over heat
Check to see what else shares the same fuse with the radio. If cigarette lighter is on it could be a penny or something stuck between the lighter and socket. That would be because when it is hotter the ac is working harder to cool the car, forcing the ac condenser to heat more. Make sure all fans are kicking on to cool it down. Most cars have two fans one for when ac is off and one for when its on. So make sure both are kicking on or that one is kicking on and off with two different speeds. You can hear the fans kicking on and off when the car is on in park. If you don't hear fans kick on check fan fuses, relays, and fan motors.
The fan will kick on automatically everytime the ac compressor comes on to cool down the refrigerant going through the condensor. Make sure you dont have a/c selected or have it on defroster if you dont want the compressor to run.
If the motor does not sense it is getting too hot, the fans will not come on. When it reaches a certain temp, they will come on. If you are having problems with over heating, and the fans are not coming on, I would suspect the fan temp sensor, or the PCM.
