Water coming from vents?

Hey guys I've got a 95 zj with the 4.0. It's been snowing like crazy here in indiana today. The jeep has sat all day, I just started it to go pull a friend out. When I started it, I immediately turned on the defrost on the highest heat. I noticed I felt tiny water droplets coming out of the defrost vents hitting me in the face? Is this just some form of condensation? Just kind of a worrisome person, jut wanted to see if anyone has experienced this? The AC hasn't worked since 2005 and it hasn't been charged since, so the AC has nothin in it.

There are no filters on the air induction . Snow can be considered an airborne particle so when the jeep is cold , it can bring small airborne particles , such as fine snow , through the system and in the vehicle . I've seen/felt it several times . Normal !

Phitmein, I don't see any kind of oily residue or anything on the windshield. How would I know if the heater core is bad? The heat works perfect, it's warm even in this weather within probably 5 minutes.

Newfiezj, yeah thast something else I had considered it would be, since there isn't a cabin air filter. Considering it's only happened one other time that I've noticed and that was last winter. I guess my theory was that when I drove the jeep early that morning, the vents were extremely hot, I had the heat cranked to the max. Then I parked it, in the cold obviously, and the temperature change caused condensation to form in be vents.

If you are not losing rad. fluid no oily sheen on the windshield above the vents and the carpet is not wet on the passenger side floor the odds are you are very good to go core wise .

I got my fingers crossed for you brother because a new core is a pain in the behind to do or have done .
