SMOKE OR STEAM FROM THE AC

All of the sudden I'm getting smoke or something from the AC seems worse on low fan speed. It doesn't smell like smoke but kindof feels like steam from a cold air vaporizer. What the H:skull1: ll?
Oh only when on ac not vent or heat.
Thanks

Sounds like a leak in your heater core.

Is the water runing out from under the middle of the jeep, it should be.

Lots of water but no sure where its coming from I just assumed it was the AC sweating as always. Heater core makes sence. Last week had cold spell and smelled like antifreeze. I thought it was just left over smell from the rad. flush 2 weeks ago. Thanks a lot guys
