Dash Air Conditioner Problem

Something has gone awry with my 2015 Minnie Winnie 22R's dash air conditioning. It has been ceasing to blow from the dash A/C ducts and blows a little on the floor. Then, when it wants to, it will go back to blowing from the dash ducts. Any ideas?

I already have an appointment at my RV dealer Wednesday for some other work. Hopefully, they can take care of this.

Have you used the blue to red temperature controller recently? Most times they are on full cool. Putting them to a warmer temperature will open a mixer valve/gate and could be stuck. Also the temperature controller works off of a vacuum and typically the little canister is under the front hood. it has a small 1/8 or so diameter hose connected to it It could have come loose or sprung a leak, Leak could be anywhere, even behind the dash.

X2 on Wayne M, the vacuum lines are 3/32, I had to replace mine on my 2007 due to mechanical abrasion causing a vacuum leak.
