Low heat

I’m not getting enough heat in my '95 Saturn. I changed the thermostat and put fresh anti-freeze in. Temp gauge is reading in normal range. Blower fan is working on all speeds. Upper and lower radiator hoses are hot. Only getting luke warm heat. Any suggestions would be greatly appreciated.

On most cars these days the heat is controlled by blending heat from the heater core and the colder outside air. What I think is happening is the blending door is stuck so it’s blending too much cooler air and not enough heated air.

I agree. The blend door is the most likely culprit.
