Check to make sure the both heater core hoses are getting hot with the engine warm and heat on. If they are, check blend air door. If only one gets hot, make sure the coolant if full. If it is, flush the heater core.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
