There is NO air at all coming from vents when heater or a/c is turned on. on 2003 Honda Civic

It was working one day but not the next. No unusual noises or smells as a warning something was going bad. Have checked all the fuses. Any other suggestions before taking it to a Honda repair shop?

Does the green indicator on the a/c switch light up? does the blower motor have power going to it PCM controls the compressor , if it doesn't see the blower motor (inside fan)come on it won't let the compressor engage.Check blower motor relay. SOME are integrated into the multi-plex of the drivers side fuse box
