The heater in my 2000 Catera will not blow any hot air. The blower works as does the a/c. Hot fluid is circulating through the hoses attached to the heater core, but no hot air. Any other ideas as to what it might be?

If you dont have any fluid loss, the vaccume hose to the heater control valve may be off or broken, or the heater control valve it self,, its behind the intake at the firewall
