2001 Chevrolet Blazer General Question

Our 2001 Chev. Blazer heater starts on hot enough but after a min. or two really cools down depending on the out side temp. at middle fan speed. The thermastat was changed.

Have the heater core checked for a restriction or an air pocket in the engine cooling system.
