Roof air/dash air connection?

My 2003 Holiday Rambler Navigator blows cold air from the dash air vents whenever the front roof air conditioner was running. Does anyone know how this is accomplished? Is there a ducting that somehow ran down to the dash area somehow?

No connection between the 2 systems.  You should be able to make the dash HVAC hot or cold independent on the roof A/C.

The air feeling cold is probably just because the dash fan is blowing the air chilled by the roof A/C.

However it would be possible for a previous owner to have rigged the coach to turn on the dash A/C when the roof unit comes on.   I don't know why anyone would do  that I have never heard of it but it's possible .
