2002 montana steam from vents

[mrfuser]

We notice that every so often, seems more so after hour or so drive, that steam seems to be coming from dash vents with Ac on. Any idea why? No overheat condition, Ac works fine, coolant levels fine, runs fine.

Thanks

just for a short period of time or happens all the time after an hour or so ? It is normal every now and then for this to happen given the right set of circumstances,weather,humidity,dew pressure,ac system,ect.... . Not to put out steam all the time but a little puff when it starts up, I have never seen this on my 03 but have seen it on fords with a good(cold) ac system.

I have seen it also, it is water vapor, a miniature cloud!
