SOURCE: I have a 99 cavalier that is overheating.

Check your temperature sending unit plug and wiring. if there is any corrosion it can cause the signal to be out of range...If it's out of range it can delay fan start up. Works like this: sender sends info to the computer, computer sends ground signal to relay, relay completes power to the fan. If the fan works on a/c, then the fan motor is good and does not need testing. A/c bypasses auto control and keeps fan on as long as compressor is running.
Also, you can have the system tested using a heat sensing "gun" Your gauge may be off a little on the high side. Unless it is actually overheating, there may not be any problem at all.
The gun test can also detect "cold spots" on the radiator which indicate a flow problem. That too can cause your symptom. Don't forget your radiator is ten years old and likely is nearing the end of it's service life. Internal blockage of core passages is common on older radiators.
As long as you have no external leaks and engine internal gaskets are good, something here has got to help!
Good luck!

SOURCE: fan on intake will not shut off

There is a relay and yes it is controlled by a intake temp sensor, they will run a long time, up to 1 hour on a hot day, have you had the battery tested, maybe it is getting weak, but if that's not the case why not just disconnect the fan motor, that is what I did, had a similar problem.

SOURCE: cooling fan

Yes, it's probably the PCM. I had the same problem, and upon replacing the PCM it started working again. If your cooling sending unit is new, and so many parts of your fan assembly are new, it's probably not receiving the signal from the sending unit. Hope this helps.

Ok when I have my heat fan on my 2006 dodge charger 2.17 it dont run hot but when I turn it off it do our when I turn on the ac it run hot


If the engine is running hot you may be low on coolant. Check this first. If coolant level ok, the rad fan may not be working to cool the engine. If the AC is operational, when you turn it on, the radiator fan should come on telling you the fan motor is ok. You still may have an issue with a fan control related to temperature. This can be caused by a fan relay/wiring/temp sensor/ecm. Make sure the thermostat is functioning properly as well

I have a 2000 Dodge Stratus and the fans are not coming on. If I let my car run once I turn it off its boiling, but there is coolant in there?


Feel the upper radiator hose. It should get hot. If it doesn't there could be air in the coolant system and may need to be blead out.
Also, if the hose is not hot, the coolant thermostat could be stuck closed.

If that all seems ok, then there is a fuse and a relay that turns on the fan (radiator fan)

Hope this helps.

Temperature gage goes up and down


The breather hose should run to the air cleaner housing or intake tube.
Check your radiator cooling fan. If it isn't working the car will run hot at slow speeds or idle then cool down after you get going faster. A quick check would be to turn the AC on and see if the fan comes on. If not try lightly tapping on the cooling fan motor with a wooden broom handle. If it comes on then you have a bad motor.
If the fan comes on with the AC then check to see if the fan comes on after the engine gets hot. If the engine temp doesn't kick it on then the temperature sensor might be bad.
If the fan is ok please post more info on your problem

Air conditioner works fine while driving. When stopped for a light, temperature gage goes up and fan blows hot air.


Hello: Check the radiator cooling fan. With engine running and A/C on open hood look down on the back-side of the grill, that's where the cooling fan is. It should be running, if not check the fuses, cooling fan relays/module if they are ok then you may have a cooling fan motor failure. You can use jumper cables to hot wire the fan motor to see if it runs.

Water is over heating when air conditioner is running. Temp is fine when air conditioner is off. Changed radiator fluid and thermostat. Fan is running and water pump seems to be ok.


My suspicion is that the fans may be coming on but they are not picking up speed when you turn on the A/C. Your car would have some of relay to control the speed of the fan whenever the A/C was turned on. This relay system would also increase the speed at which the fans run when the engine heat turns them on too.

Try starting the car cold and turning on the A/C right. Even though the engine is cold the rad fan should start up when you switch on the A/C. Once the engine gets hot the fan speed should increase accordingly when you switch on the A/C.

I'm not familiar with how Chrysler makes this work so I'm unsure what to repair but this is most likely your problem. Hope this helps.

if the fan electric fan is not comining on, you need to check the fan motor to see if your motor is bad on the fan. check it by running a hot wire directly from your car battery to the fan elecrtic plug.
