Ram Heater or not?

Hi Guys,
I have a 2001 ram 2500 4x4. a/c blows cold, and heater will melt you out.
The problem is no control over the heater. Its either full hot or full cold
The temp control panel has been replaced with no change.
No matter where you set the controller in the mid range, it goes to full hot, cold only works in the full cold position, no middle ground.
Any help is appreciated
Joel

Welcome to Allpar. If you have replaced the HVAC control and it is good, that only leaves the temperature blend door actuator motor (servo). It provides feedback about the temperature door position back to the control module and if that information is missing, it will swing full hot or full cold.
