Sorry you're having trouble. Two thoughts - if it's ventilation related, would pulling the outside cover / access panel off, and dragging a fan there - possibly help?
Second - call a Mobile RV Tech. Find one that you like and trust. I'm not trying to get Negative Nicky or Doom and Gloom - but most RVs will need a lot of things fixed over the years. Waiting on the dealer is usually ill advised.
I've gotten to know a Mobile Tech and he's the first one I call when there's something I can't fix myself.
