I own a 1999 Blazer with a 4.3L vortec engine. I had this problem and solved it by topping up the coolant level.

Why does heater defrost vent not open on a 1989 Sunbird and cold air blow from dash vents but no air blows from heater defrost vents and where are the enter and exit hoses for the heater coil?
I don't know why the vent would not open for the defrost, but it may be related to the fact that your heater core is blown.
