We are at a site and engine etc has long been shut down but there is a light air flow coming from the dash AC vents. The AC fan is set to zero and coach is totally off, what would be feeding air through those vents?

Don’t know about a London Aire but anytime I leave my dash AC on outside air I can get air drawn in from the vents, or blown in by the wind. Switching the system to recirc before shutting off the engine seems to solve the problem.

Depending on the dash system , the recirculation door may not hold it's position .
My vacuum controlled door will slowly open in a week or ten days ; and I park for 5 months ; so I tape over the fresh air inlet .

Learn something new every day! I believe you've just explained some of the dust in my rig up around the dash and those vents while parked in storage. Was totally random each time I stored the rig and it had me scratching my head. I now have a new step for the ol' checklist... Thanks!
