Intermittent dash blower failure
Every other drive or so, Evans system will not send airflow to the front blowers -- only the windshield (defrost) blowers. I believe this is a fail safe and there is a vacuum system problem, but beyond looking at the vacuum reservoir under the hood and not seeing anything grossly amiss, I have no idea what else to check.
Newmar wants me to see a tech, but that will take a while. And since we have had no actual dash A/C since we bought the rig in March (separate issue I've deferred until winter), now I have to resort to rigging fans all over the place to keep me from melting whilst driving in this 100F heat!
Any thoughts welcome, except the links to the Evans debugging diagnostic guide. I've gone about as far as I can with that (quick inspection of reservoir) before running out of imagination/expertise to know what they are saying to do. :-)
