Hi and thanks for using 2carpros.com

With this type of problem, either it's low on coolant, the heater core is plugged, or the blend door isn't operating. First, you mentioned the heater core hose is hot. Are both hot or only the supply?

Take a look through this link and let me know if anything helps.

If nothing there helps, confirm the following:

Coolant is full
Both supply and return heater core hoses are hot
Blend air door actuator is working.
Does it have automatic or manual temperature control

Let me know.
Joe

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