I imagine this is auto temperature control so it needs to be scanned for codes to see what is wrong. One thing your mode actuator is not working so it is either bad or needs a reset. Also, since you changed control head it may need programming to your truck. This will need to be scanned for codes by a mechanic to see what is wrong. If this is a manual control where temperature is not set get back to us.
