Not getting heat from my 1999 Chrysler lhs

I've checked the hoses going to heater core, both are hot to the touch.  Can't keep my hands on either one of them.  No leak coming from under the dash.  I've taken panels off to look at actuator.  When I change it to defrost, or floor or panel, each time it rotates.  My question, is there another blend door that regulates the direction where the air pushes through?  Is there a thermostat that, when i change the temp to high its suppose to make the blend door move more?
