Are both of your lines hot going to the heater core? if they are, blend door actuator has taken a nose dive. Usually the default position, the air goes to the defrost location at your windshield. Can you get the HVAC system to go from the vents to the floor and back? that would eliminate the blend door.

You check your in cabin air filter to see if it’s clogged
