to clarify; you have airflow from the blower motor but only cold air?
if thats the case; start by checking the coolant level.
if thats ok, check for movement of the temperature blend door when you move from full hot to full cold position.
also...how is the fuel mileage? bad = thermostat stuck open..will set a dtc.

You said that the heat stopped working on the drivers side. Does that mean it was working on the passenger side? If so you need to look at the blend door actuator.
