Depending on how COLD it is where you live right now the Fans on your car may not need to run.
The Cooling Fans Relay on my 1996 Camaro went bad and I had to replace it. Again, If you are in a cold place right now (if the outside temp is not getting above 10 or 20 degrees for example) the car may not be generating enough heat to kick the fans on. Does the car have warm heat? If the heat is not getting warm the thermostat on the car may need to be replaced. They are very cheap to buy but can be time consuming to fix depending on which engine is in your car.
The A/C does not HAVE to be done at the dealer. You can have Air Conditioners serviced at several different mechanics shops. I would look in the yellow pages and try to find someone with the correct equipment to do a good job on your car. Since hot weather is a couple of months away you have time to ask around too. My experience is that hourly rates at DEALERS is much higher than it would be at a good Mechanics shop.

What do you mean all the time? when engine is running?
if you are on a hot climate the fans help dissipate excessive heat build up when the vehicle is stationary. what is the water temperature tell you when you are not moving?
could be that the thermostat is not 100% functional to fully open after engine heated properly and the computer attempts to remove excessive heat to prevent overheating of the engine or the engine temperature sensor is giving false readings that tell the computer that the fans need to be on to do the above.
i recommend that you do a scan of the engine, first to check for errors history, then if none are found while driving and afterwards stationary to see what the temperature reads are.
after engine shutdown usually they can still remain on up to a minute to eliminate excess heat from the radiator.
I USE A TEST LITE TO CHECK FUSES.IT IS QUICKER AND YOU DONT HAVE TO REMOVE THEM. I HAVE FOUND THAT I WILL FIND A BLOWEN FUSE THAT IS NOT RELATED TO THE CURRENT PROBLEM ACORDING TO THE LABEL BUT IT FIXES THE PROBLEM SO CHECK IT TWICE BY TESTING ALL THE FUSES
Hi, you have either a bad cooling fan motor, or a bad relay for the cooling fan motor.
When it begins to heat up, look and see if the fan is running. You can go to a parts store and buy the relay, they will show you where to put it in. If that doesn't fix it, then you need to have the fan motor tested. It could also be a circuoit in the computer gone bad. This happens quite frequently.
The reason it heats while at idle but not while moving is, when you are moving, air flows through the radiator. When stopped, the fan has to push the air. If you have AC, all fans should run when the AC is on.
REPLACE THERMOSTAT.ITS STICKING CLOSE TO KEEP COOLANT FROM CIRCULATING THROUGH ENGINE AND RADIATOR. THE FANS SHOULD COME ON WHEN VECHICLE SETTING AT A LONG IDLE.THE COOLANT TEMPERATURE SENSOR GET TO CERTAIN TEMPERATURE WHICH WILL COMPLETE CIRCUIT PCM SEND POWER TO COOLANT SENSOR THEN TO COOLANT FANS RELAYS AND FANS.IF VECHICLE OVER HEATING WHILE MOVING THERMOSTAT FAULTY.IF YOU TURN AC AND COOLANT FANS DONT RUN CHECK COOLANT FANS FUSE AND RELAY.IF COOLING FANS DONT TURN ON WITH AIR CONDITIONER ON EITHER COOLANT TEMPERATURE SENSOR FAULTY OR PCM FAULTY.IF ALL LOOKS GOOD.IF ENGINE OIL LOOKS LIKE MILK SHAKE.YOU HAVE BLOWN HEAD GASKET.
Not much info, but i will go with it. Two things, i would first check and make sure that your fluid level is high (antifreeze) and that it is the correct color or consistancy. It was a common thing of these cars (chevy) of these years to have orange coolant. which is fine, but when mixed with the green stuff it would turn all the 'dead spaces' or the slower moving spaces to gel up with a pudding feel. this would cause the sensor that turns the fans on to always think its cold. the other thing i would check is that the electrical connection is solid. if you can move the plug around inside of the fan motor then its too loose, infact if this is the problem and you are able to run the motor and reach for the plug and jiggle it while its running, and the fan starts and stops, then there is your problem. If it was my car i would just simply take some high heat tape, possibly duct tape or some sort of hvac tape, and tape it to one side where it works. If i paid someone to fix it i would expect them to replace the fan. any extreme (or anything in between) should fix that problem. If it is the coolant gelling, you will have to do a full system flush, start with plain water then a vinegar mix, then a commercially availble flush, follow the directions.
well so long as the engine dont over heat whats the problem?
some cars the fan only ever works after its been running for about half an hour and only then for about 30 seconds,,,
just keep a close eye on the heater gauge if it stayes in the normal its doing just fine, dont worry about it,how long have you had this car? has it ever boiled up on you???? dont fix it when its not broken
