The blower works but there is no heat coming out. The engin is not over heating. The gage appears to be working. What could be the problem?

Hello,

If the fan is blowing but you are only getting cool air, then it could be due to a faulty blend door actuator.
The blend door actuator controls the hot or cool air flow. Over time the actuator can malfunction and fail. Typically, when that actuator fails it will fail at either hot or cold side.
It is located under the dash in the HVAC panel.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.

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