I've been trying to help the owner of an Itasca Ellipse 40FD owner with a basement air conditioning problem, but I'm out of my depth since I know nothing about the Ellipse.
He's mentioning an A/C fan on the drivers side rear that I don't have on my Itasca 35U. I'm thinking that it has nothing to do with the air conditioning (engine compartment ventilation?) but I could be wrong.
If you can help, please respond to his original thread so we have continuity:
