In the morning on warm, humid days I get condensation on outside of front window. This is at bottom center where the vent on top of the dash blows air up onto window.

This happens when I run the AC on cool. Without defrost on. Technically, I understand why. But, I never had this happen on any of my previous Lexus'.

The coverage is about 3 inches high and width of the inside vent.

Doesn't matter what position vents are in. Or, if S-Flow is on or off.

My airflow changes correctly as I change the settings.

Any ideas why this is happening.

Very annoying----



Thanks

Quite normal this also happened to me on my MB under certain atmospheric conditions, don't worry run the wipers

Tried in auto setting? Or draw outside air or not?

hmmm?

I don't use Auto. Never have.

This happens more in mornings when I leave garage. Maybe the garage holds more humidity overnite. I can try the Auto and opening windows for a minute.

But, as mentioned, never had this issue before--

Thanks Cocal,

I must have accidentally started 2 same topic threads. Mods can delete one.

I can run wipers. But, it just re-condenses. Plus, if some bugs are on windshield, they will smear. And, I don't want keep using the washer fluid. I know, I am OCD.

I haven't seen this issue mentioned before. So, was wondering if a car ventilation system issue.
