Make sure it's full of coolant first then check to see if there is a blockage if both hoses are about the same temp then you may have an actuator in the heater box broken. If this is auto temp control -like you set the temp then get it diagnosed what is wrong with it as it can be a sensor or anything.

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