Check coolant level to ensure it is full. If this is okay, feel 2 heater core hoses to ensure both are warm. If only one is warm, this indicates a clog in the heater core.

Post results of inspections and I will follow up.

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