My fan blower is not working and it appears no cold or hot air is coming out of any vent at all.

fan control relay. go online for parts and location

You can hear what ? Blower motor ? Probably the blend door actuator is not working . I 'm questing because I don't know what make vehicle you have .

CHECK FOR VACUMN OR SWITCH

blower fan motor bad or fan switch or fuse

First check fuse 103 in the battery relay box and swap the blower relay with another similar relay, such as the horn relay. If this isn't the problem, you should hot wire the blower motor to the battery to make sure it works. If all of that is good, next check the switch/motor controller. Take the connector off the blower motor and check the voltage in the connector. With the key on, the voltage should be 12 volts with the fan setting on high. You can also use a 12 volt test light for this test. If there is no voltage, replace the switch/controller at the control panel. If you need any instructions or have any questions, please get back to me.

Check the brushes on the blower motor that circulates the air in the car.

Did you check fuses located on battery?
Possible causes , fan itself , but it would have nothing to do with overheating.
Fan resistor (final stage controller) , not for overheating either.
And the most common on this cars is radiator fan control module , basicly a few relays in one.
You can check fuses by yourself but for the rest of it probably mechanic shop is preferable.

It sounds like your cabin air filter has stopped up common problem on these cars. You have to remove the glovebox to get to it. If this filter stops up, your fan will be running on high but hardly anything will come out of the vents.

Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.

Check the water contol valve operation ( under hood connected to heater hoses), do you have a full load of coolant?, also air mix door under dash, is the temp of the coolant hot?.Check them all out, you'll find it
