Forest; thanks I was aware of that and whatever fan(s) drive those side vents I know they are working. What I'm less sure of is if it is the ones under the dash. I could feel no vibration in them when the switch you mentioned was "on". I'll follow up further to verify.

Hope you and Cindy are having a great summer, we've had a couple of terrific trips and as soon as I pry myself away from Zen and the compulsive maintenance of motorhomes we'll have more.
