FORD E-SERIES VAN HEATER PROBLEM

1997 Ford E-Series Van • 270,000 miles

1997 e 350 diesel van can't get heat out of heater. Heater core is warm, 2 doors under dash open & close when controls are adjusted from AC to heat. Blower motor works but no warm air comes out on driver side or passenger side. Could this be a vacuum leak problem? When van is off heater controls function for a while but quickly run out of vacuum. Any suggestions?

Are both heater core hoses getting HOT?
