Hi typer2009,

When there is no air coming out, the usual fault is a bad heater fan motor. Give the blower motor housing behind the glove box some banaging with your hands and if motor starts working, it is due for replacement.

If it does not work, unplug the fan motor connector and test for voltage at on of the terminals with ignition switch turned ON. If no power is available, check the blower motor relay in under hood fuse box.
