Q: Heater is not working when I turn heat up and on.

asked by on

I turn my car on and put the heater on and cold air blows out. I've changed the blend door actuator, fuses, and checked the coolant levels which were all good. I also checked the two hoses that go to the heater core to see if the heater core might be clogged but both hoses still get very hot. Would you recommend me still flush out the heater core in case of it being clogged?

My car has 163000 miles.
My car has an automatic transmission.
