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.

Chevy trailblazer engine gets too hot only when i blow the air conditioner


always check coolant level first, then if ok. check fan for a/c it should come on and run anytime the a/c is on. so turn a/c on and see if fan kicks on right away if not check relay.
hope this helped.

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.

Air conditioner fan runs all the time. Turn on key the fan starts. Car is not hot, has been sitting overnight Question how to turn off so it only works with the AC


I would suspect a stuck cooling fan relay. Your going to have to locate the malfunction to get the operation that you seek. Reference owners manual for lcoation of the cooling fan relay and try switching it out.

When I turn my car off the air conditioner still runs-I needed a jump the other day because it ran all night and wore the battery down.


OK, if the relay for the A/C fan is bad, then the radiator's fan will keep running after turning off the ignition. Also, if the fan for ventilation of the A/C in the cabin stays on after the ignition is turned off, the relay for that is bad.

Good luck on this repair.

Air continues to run with engine off


The air conditioner compressor is driven via belt by the engine; if the engine is off, the compressor is off = no AC.

You didn't mention which fan is still running but I'll assume it is the one underthe hood, not the one that circulates passenger compartment air. 
What is running is the electric fan that assists with cooling of the heat exchanger of the AC system. You probably have a thermal switch or relay that is not releasing.


Locate the relay/fuse box and check if there is a chart of the relays and fuses to locate the one that isn't releasing and try swapping two relays with the same part number on them to check relay function.

Cooling fan


i would deff check the relay i had a problem with my relay going out on my 04 but i just ran my fan to a togle switch so i can turn it on and off when i want it on when im in dead stop situations like traffic and also when your ac is on the fan has to be on or your ac will cut on and off to keep your car from really over heating in a hurry if your not moving, but i also run my car at the track and it helps to keep it cooler when racing down the drag strip.
