Check the A/C control unit for fault codes.Feel the coolant hoses going to the heater radiator , are they getting hot? if not you may have an air lock or a coolant circulation problem ( check water pump).

Just to add to this one the first thing i would check is if both heater hoses are getting really going into the fire wall thats your starting point.If they are really hot then you have a blend door issue.Let me know what you find.
