    Sorry for the confusion, I was thinking that my question will go under similar problem icon. I look for the information using a 2005 chevy cobalt.
    My car is a 2005 chevy cobalt with a 2.2 liter engine. The fan is electric with plastic blades

    Thank you for you quick reply

    What make/model/year is the vehicle? If it's been around for awhile, your fan motors might be going out-this can make a loud noise. Are the blades metal or plastic? If they're metal, they might be bent and are making contact with the shroud as they turn.

The noise is the drain on the belt drive system upon AC start up, the belts may need to be tightened or the AC compressor clutch is in need of replacement, if you are saying when car stops you mean the engine is shutoff then this statement does not apply but if you mean when the vehicle comes to a stop at say a stop light then it applies.

I have a 2006 Mazda3. I noticed whenever my air conditioner or heat is on it makes a sound like a lawn mower when I acceralate. Any ideas of what this could be ?

Well, I think you can rule out the AC/heater fan inside the car. That would make noise even just sitting in the driveway.

Many/most vehicles are designed to run the AC compressor not only when the AC is on but also when the defroster is on. This is to keep the AC compressor lubricated through the winter months also.

It should not be a belt problem as that belt is always turning anyway which should then rule out the pulley bearing at the AC compressor.

I do suspect your problem is a major internal failure of the AC compressor. This can be easily checked by a technician [or yourself if qualified]. Locate the electrical connector at or to the AC compressor. Two people: With the AC turned on, in park, increase the engine speed so you can here the noise. Disconnect the AC compressor electrical connector. If the noise stops instantly, the compressor has failed. A quite expensive repair. Have a reputable shop locate a re-manufactured compressor for you. That will help some on the cost.
Bestaluckto you!!

Having multiple intermittent problems

I guess the overall answer is yes it could be the ECM.
Code 16 is high or low system battery voltage.
Code 21 and 22 are both for the throttle position sensor.
And code 43 is for the electronic spark control which controls engine spark timing.
The ECM grounds various relays to make things happen such as turning on the cooling fan. So a faulty ECM could cause all of the symptoms. But so could a wiring problem in one of the harnesses.
Especially a ground problem somewhere.
If the alternator suddenly starts overcharging the system the ECM can shut down the car to protect the circuits. Unusual, but possible.
This info may not help much, but somebody is going to have to test the circuits when the engine dies or when the symptoms happen.

Swish noise when turning with fan on.

The AC condenser is not able to drain the condensate and it is trapped. Locate the condensate tube and clean it out.

Vibration and noise when blower fan for ac or vent is turned on

Those fans can get noisy. They don't last a long time. The motor has carbon brushes that wear down and they may squeal when they do. They are about 100 dollars at any chain auto parts store

We put a brand new radiator in my mazda 323, but now when we start the car, the temperature rises at an extreamily fast rate. i noticed that both the radiator fans are not working. i have no idea why

one fan is for the AC while the other is used with the motor heat,, when you replaced the radiator did the new one have the same number of fins,, Hope so,, next check the thermostat you may have dislodged some sludge thats preventing it from doing its job correctly you may have to replace it too ,, as far as the fans ,, check once the motor is heated up with the ac off that the one fan is working, then turn on the ac to see if they both kick on, If not,, check the fan relays and fuses

Groaning Noise While AC is on

this sounds like the AC compressor is failing, the engine idles slower in drive so noise is more apparent. you are likely going to need to replace it soon.

Squealing NOISE possibly from fan belt

If the noise going away every time u turning off the ac it's probably your ac compressor belt.however i will suggest to take some vaseline and rub it all over the exposed parts of your drive belt.
