Blown Fuse

Usually the first thing to inspect when the blower fan stops working is the fuses to see if any are blown. Locate the 10A cluster fuse or the 25A HVAC fuse in your car manual, and examine them to determine if they need replacing. The car owner's manual will tell you where to find the fuses that are connected to the heat and/or air conditioning. On the interior fuse panel of the car, a 30 amp fuse is labeled "Heater" or "HVAC."

If the fan only works on setting number 3 or 4, or just on the highest setting, it is most likely that your blower motor is failing and is about to die. Use a voltmeter to test the amount of voltage at the blower motor connector with your ignition on and AC running. If it reads 12V, the motor needs replacing.
-
Another thing that causes the blower fan to malfunction is the Automatic Climate Control System (ACCS). If the ACCS's settings are off, it may cause the fan to stop working. If it is the climate control on the car, typically it is a bad thermostat or electrical circuit that is the culprit.
