I have a 2001 3.0 dodge stratus r/t that only blows cold air. I've flushed the heater core, both top and bottom hoses(heater core & radiator) are hot. Coolent is at correct level and I replaced the thermostat. What else should I fix/check to resolve this no heat issus.

SOURCE: 2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

I would try to replace the thermostate again, Sometimes these can get damaged in the warehouse. Cheap to try it again, $12-$15

SOURCE: why does the heat in my 1999 dodge stratus only

the flap in the air box may be broken or not ingageing all the way check for vac leaks and switch the air from defrost to vent and see if its working properly

Sounds like you have air trapped in the heater core when you flushed the heater core. loosen the upper most heater core hose and run the engine untill coolant seeps out. Wait until the coolant has reached running temperature.

There is a problem with your climate control. It is not allowing the vent to open that allows air to pass through the radiator.
