    when I leave my bunk a/c on high when I go to sleep, a few hours later there will be no air blowing thru the vents. the fan is still blowing, and the switch is still working for the flapper door cause I can get warm air by turning the controls. it just seems like there's a blockage in there sometimes. any ideas?

    Do you have a lot of stuff stored under your bunk? If so, might be blocking the intake.

    Get out look underneath checking to see if the ac lines have ice on them. If yes then check to see if the lines going to the front are iced. Yes front expansion valve. No rear expansion valve.
    Check rear intake filter. Change it its 9 bucks.
