Floor air vent fan is constantly on

Hi
I have a 2001 Winnie Minnie 27. The floor vent constantly blows air.
The control knob on the dash is in the off position. I removed the grill and can only see a hose that looks like it goes under the rig. Any ideas as to how to fix the issues without taking it into the shop. It doesn't cause any problems but is annoying to hear the fan on all the time.

Thanks
Class C

    Water Hose or an Air Duct kind of Hose? It sounds like you might have the Chassis Heat/Vent/AirCondition (HVAC) system confused with the House Furnace.
    At least on a rig we had, IF:
    A. LP Gas Valve at the Tank was OFF and...
    B. Furnace Thermostat (on Wall) was ON...
    ... Furnace Fan would run constantly. All the Thermostat knows is whether its Set Point has been reached. It has no way to know the LPG is Off or failed to light. So the Fan keeps running.
    Example: Thermostat ON and set for 72* and room temp 68*. Furnace'll think its job is getting to 72* and runs. No LPG, No Heat, No Stop.
    That or some kind of stuck relay in the Furnace. I don't think that Wall Thermostat has "FAN ONLY" but that'll surely produce what you're experiencing.
