1995 Mustang V6 Heater Blows Cold

I just bought a 95 and the only problem im having on it is the heater. Whenever I'm at idle, the heater will only blow out cold air. When I get to a stop sign or slow down again, it blows out cold air. However, at higher rpms it blows out hot air. Can anyone help me with this issue?

If the V6 coolant re-filling procedures were not followed exactly there could be AIR trapped inside the motor. For the V6's with ECT sensors, the ECT sensor will be in contact with air instead of water. This complicates trouble shooting because the ECT sensor will read LOW.

Note, if there is air in the cooling system, the source could also be a leaking head gasket.
