Just warm air coming from vents. Both hoses going into heater core are very hot, blower and air conditioning are working. Blower works properly as well. What can I do?

Good morning,

I would try flushing the heater core. Remove both hoses and use a garden hose to flush through the core. Go both ways until you get a clear even flow. Then hook it back up and see if it works.

If it does not, then the core will have to be replaced.

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