A/C question or problem

when i run my a/c for more that 15 min white smoke or fog or something comes out of it. it has no smell and didnt or hasnt made me sick any body have any ideas on what it is or how to fix it? its an 84 2.8l blazer 4x4

it's called condensation! nothing wrong there

i have never seen another a/c have "condensation". mabe for a second but mine does it the hole time.who else has this "condensation"?

When my heater core started leaking, I experienced the same symptons (white steam/smoke). The floor of the passenger compartment eventually became wet also with the telltale smell/feel of antifreeze.

why would the heater core have anything to do with the a/c and my heater core is leaking tho but not bad at all i just saw a little drop under the dash. if i buypass the heater core will it stop i never use it any ways its to damb hot here.
