If your fan is not working, the AC is prevented from coming on. This is a safety so the evaporator (cooling heat exchanger) does not ice over.

Fix the fan problem, and the AC will work.

If the fan does not work at any speeds (lo, med, Hi). Then you have a blown fuse or wire disconnect.

If the fan works on HI only, then your blower resistor is shot. This is a common failure and can be replaced at your dealer or by yourself if you are handy.

When the ac is on it will cool my car only when I'm driving, whenever the car is idling or at a stop sign it just blows hot air and the temp gage will go up.

Looks like your auxiliary fan motor assembly is not working. That fan is the one that cools down your aircon condenser on the front of the engine. When you turn on the A/C it( aux fan ) should run, if not, the problem will be either the fan motor or the switch relay. Open your fuse and relay box in the engine compartment ( black plastic box ), near the fender, look at the sign of "winter ice" that is the relay, and switch on your ignition( don't start ) and aircon a click sound should be heard or felt on that relay. If not, pull it out and take a similar relay on that box and insert it in that relay socket. Fan should run, if not the fan motor is the problem.
Better go to your technician if you can't fix it y yourself, I am just pointing out the problem that should be done for DIY job.
Hope that helps you out.
Thanks for asking FixYa!

Do I need to replace a sensor because my radiator fan runs all time while the car is running?

Do you have your a/c or defrost on? The fan will kick in when you run the ac or defroster.

If you are sure ac & defroster are off, then the fan sensor is suspect.

Hope this helps.

Cooling fan not working

This is a thermo fan and is temperature controlled it will only start up when the vehicle gets hot. Take the vehicle for a drive and when the thermostat opens up and the temp guage on your dash gets up half way that is when the fan should start aprox.. get out of your car and leave running and check to see if its working..

If not check all wires going to plug at the fan,
although the aircon one should come on when the aircon is switched on. If you have a bit of electrical wire handy you could make 2 lengths atach to the neg and pos of battery disconnect the fan plug and attach the other ends of the wire it doesn't matter about polarity as it will just run backwards, if the fan runs then there will be a problem with the sensor or wires see an auto elec,, ******Keep hands clear of fan when ever key is in the ignition as it can start at any time******

Try replacing the blower motor resistor. That controls the speed of the blower motor.

2001 PT Cruiser , have replaced the fan motor twice , a/c fine 2 weeks then blows it again ,something electrical I know ,but what ?

Check the voltage output of your car with the engine running. It should read 13 to 14 volts. only. Higher than this will cause damage to the fan motor, and other 12v gadgets in your car. Is this happening? If not, then, check the aircon evaporator for grounded wiring connections. This is the line from the fuse box terminal to the line going to the aircon. Grounded line can cause a lower voltage reaching your fan motor, forcing it to run undervoltage, overheating it. Send us your e-mail so we can give you further
