A/c compressor works fine and the blower motor works and shutdown right? it is the problem with the blower resistor or with blower motor relay. try to direct the resistor irrespective of the speed. hope the problem may be solved.
When the fan is not working, does it not work in all speeds or does it only work on high speed? If high speed is all you have, the fan resistor is a likely culprit. If you have no fan operation at any speed, leave the switch on high (with the ignition key in the run position, of course), and smack the fan with a rubber mallet. If it starts working, the fan motor is on its way out and will need to be replaced.
The fan will not always be on it will only come on when the engine needs cooling then it will turn off and it will cycle this way on and off on and off this is normal dont worry if you dont see it on. When you turn the ac on this will turn on the fan while the ac is on and stay on till you turn off the ac this is also normal most people think the fan should be running all the time but its not like that. Dont believe me try this but just watch your temperature gauge it will go up a little hotter than normal turn your car on leave the ac off and just let it idle for about 20 to 30 min in that time you will hear the fan come on then turn off. If everything on your car works right then the fan should have came on and turned off dont let the temperature gauge get into the red zone. But as you watched your temp gauge it should have gotten a little hotter than normal but not in the danger zone and the fans should have came on. If you see it getting into the danger zone turn it off and have the problem fixed.
There is a resistor panel that controls the fan speeds behind the glove box on the dash. You remove the glove box and you will see the airbox. Sitting down in the left top, with 2 screws holding it in, will be the resistor panel. It consists of 4 springs and a resistor. All out of veiw, inside the airbox. Remove the 2 screws and unplug the plug. Pull out the old resistor and replace with the new one. It only cost around $15-20 bucks at the local auto part store. This will get your fan blowing. If your fan is blowing but the air is not cold, I would suggest to check and see if the compressor clutch is working properly. If not, try giving it a light tap while running. If it is working, you may want to recharge your freon.
Switch ignition ON.Press and hold lock button for 10 sec.Switch ign.Off.Remove key from ign. switch.Wait 5 sec.Sinchronization procedure complete.Confirm sinchronization has been successful by locking,double locking and unlocking vehicle. Repeat abuve procedure to sinchronize any remaining key.Good luck
Probably a faulty relay or fan on it's way out. Check with key off, battery disconnected & see if it wobbles or is hard to turn at all. Should move freely. Relay should be labeled in power distribution box, or fuse/relay box under hood.
I'm sorry, but I'm a bit confused regarding your statement where you said, "I drove it without a air filter for 4 days the put in a new one but it still wont start." Please clarify. Thank you, jetski224
