rodkling Posted November 16, 2020 Share Posted November 16, 2020 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?

Guest Ray Davis Posted November 16, 2020 Share Posted November 16, 2020 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 . Link to comment Share on other sites More sharing options...
