Freightliner heat

New Fleetwood Providence on Freightliner chaise . I can't get enough heat down on my feet when driving in 30 degree temps. Got down and checked the diverter valve and it turns for each setting but I don't see any duct opening for the feet. That and there seems to be some cold air flowing in from the firewall but no visible openings.
Any ideas?

thanks

Same problem with a 2000 freightliner chassis. Good heat at low speed, and then not much at highway speed. Running the heat on recirculate helps a little. Running genset with electric heater helps a lot.
