There may be an electric fan on the A/C condenser , ( under the front behind the gen set on my coach ) that should run any time the compressor cycles to aid the system , and when your moving the air flow takes over.
These electric fans can fail , or pick up road debris and blow fuses, so check all the fuses and if they are ok , report this with your dash vent problem to Newmar.
Freightliner is correct , virtually everything above the frame rails is installed by Newmar.
