Total A/C and Heating Failure after shipping

I shipped my car from LA to NY, a 1996 3281c with 80K mi. I just had the 75K maintenance done before having it shipped and everything was working fine. When I received it today, the climate control unit seems to function electronically, but no air comes out. No hot air or cold air, no matter what the settings are on.
Any idea what mechanical or electrical failure can prevent any airflow?

Thanks
