Just checked the temps. The one heater core hose is at 130 and the other one is at 120. The heater core is at a little over 100. -

Just got done with a long trip. The heater core hoses in the firewall are hot. The thing I noticed is that the hose going to the thermostat is hot but the other one is not. Clogged radiator?? -

Replaced the climate control unit and the thermostat. Still no heat. Not like it had a week ago. On recirculating mode it comes out at about 68 degrees when it’s 46 out. -
