Our 2009 Sedona has just recently began to fog the inside of the windshield when sitting, usually overnight. And sometimes not at all.
There is no obvious leak, all the door seals are intact and seem to be in good shape. The floor is not wet, there is no smell of antifreeze like the heater core is leaking. We always run the car using fresh air, not recirculated.
I have made sure that the AC evaporator drain tube is clear and the windshield cowl drains are clear. Rain doesn't seem to make it happen any more or less and the outside temperature and humidity are normal for the area and this van has never done this before.
Obviously there is a moisture issue somewhere but I am at a loss as to where to look next. Any tips?
