It could be the blend door. However, with the engine running, hot, and the heater on, check both heater core hoses to make sure they are both hot. If you have one hot and one cold, the heater core could be plugged.

Let me know what you find.

Frustrated, Flushed Core Twice Good Water Flow, Pulled Console Door Is Working Properly. Good Heat From Rear Core. Puzzled, Any Ideas?

Heater Not Working

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