Question type: Maintenance & Repair

I have a 2010  Dodge Ram 1500.  Air conditioning works great but heater is not blowing hot.  It is the same temp no matter where I turn the dial.  I changed the blend door actuator and it didn't fix anything.  What is my problem?

Sounds like the heater core. Do you smell antifreeze inside the truck or is the floor wet on the front passenger side?

No antifreeze smell and no wet floor on passenger side.

The thermostat is either open or is missing inside the thermostat housing on the engine
