Could be a bad blower motor, resistor or heater controls (fan switch). You will need to use a multi-meter to see if any power is getting to the blower motor.

a mechanic cleaned the contacts on the selector button on my 02 and got it working , but you'll need the tester to see if that is the problem , start with the motor
The air/heater doesn't blow out. Nothing happens when you turn on the fan.
