2008 Ranger - I'm getting steam / mist from my vents

[deeman]

About a week ago I started getting steam vapor coming from my vents. It seems worse when I turn the AC on. Temp gauge is fine and shows no overheating. Mist vapor really does not have a smell. The first time I noticed it, the mist was pretty thick and I could see it coming from underneath the hood on the passenger side near the windshield. Plugged drain line? Heater core?

Thanks!!

On a hot humid day with the A/C on high, you should have water dripping under the truck. If you don't, the drain is plugged. Check the carpet over on the pass side, it may be wet if the drain is plugged.

Yes, plugged Evaporator drain

Comes out the firewall below the bottom of Engine bay heater/blower box, but closer in line with hoses to heater core
Just a small nipple end of a hose is seen
