Engine and AC fans start spinning


If that is the same thing as Defrost, the compressor will run even if the ac button is off. The compressor runs to dry the air blowing on the windshield.

Overheating problem, what is the most probable cause?


You need to stop using it immediately before you
cause some damage or more than you may already have
That is just common sense. It should not overheat or
be any different than it was in the past without problem

The car has to be checked over/diagnosed,tested,etc for
various issues to resolve

Borrow or Rent a car until resolved

No way to guess at the problem

You should have some type of codes avail even
if the check light isn't on,you need professional help
to get a start on resolving

The timing belt maybe worn & jumped or the head gasket
bad.

Over heating isn't usually a cheap repair unless the thermostat
sticks partially closed

The RPM moves around the car is 11 years old,so it may just
need a though going over

Timing Belt,O2 Sensors,Exhaust Converter,Spark Plugs
and such

If you depend on a repair shop to do things & don't
have the knowledge to request work done throughout
the year,then you run into a lack of proactive preventative
maintenance situation. Most things are simple looking
back, once resolved

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.

The a/c compressor don' kick off it stays on all the time


Make sure you have the windshield defroster off , the cars computer turns the AC on to dehumidify the windshield as it blows in order to speed the defrosting of the inside glass.
If you have made sure the defroster is not selected on the climate control center , you may try a few other things to determine where your problem lies...
With the vehicle turned off , key out of the ignition , open the hood and unclip the small white plastic plug off of the compressor ( the electric clutch actuator plug). Start the car and see if the clutch is still engaged ...
If it is engaged , you have a locked up clutch on your compressor.

If the clutch disengages when unpluged ,turn the engine off and plug the clutch back in.
I would next determine whether or not the relay in the fuse block is malfunctioning..

The A/C system is more complicated than a switch and a power source .. When you push the button in the car to turn the AC on (or have the defroster on), a signal is sent to the PCM module , routed thru a pressure sensor on the AC coolant line (which has a 5v reference voltage) , back to the PCM where it is determined by the pressure of the coolant (freon) how fast the condensor fans will run , and a relay in the fuse block actuates , sending a 12v signal to the clutch on the compressor.

When I turn off my ignition, my heater fan will keep running


I just started experiencing the same problem. Yes, typically after rainy days, I can never get the interior lights to go out after the ignition key has been removed. The car acts as if there is a door open. Now, my latest problem is with the heater fan. Of course, putting the control in the "off" position will turn it off but you can turn it on and off with no ignition key installed. I'm also having problems with my heater core too so it's been a pain in the but!!

I believe this problem has also caused my battery to die which is why I'm on this site in the first place!! I can't get into the car with the keys and the dead battery won't allow me to unlock the car!! When it rains it pours!!!

No heat - ac stays on blowing through defrost vents


If you have the heater directed to the windshield, the AC will turn on. Move the control away from defrost.

2002 Chevrolet Impala overheating while idling


the thermostates on the 3400 engines are late because the fans kick in at the last moment. if you run your ac on you will notice that the gauge stays in front of the half mark or right on the half mark. that is because when you turn on your ac your fans will kick in earlier and stay on the whole time the ac is on. if you run your car with the heat on or nothing on that leaves the late thermostate to kick in verus you turning on your ac and it by passes the thermostates and runs the fans once the engine gets at at lest 120 deg. i use to have a 2002 and i had the same problem. this will keep your engine cooler. also if you don't want your air on just turn on your windshield defrosters (not the back windshield) and that helps keep your engine cool because your defrosters use your air compressor which is really your ac. so it still kicks the fans on earlier.
