Hi,

After running the AC for a couple of minutes, I get odorless fumes from
the AC vent of the car. It does not condense in my hand when I place my
hand in front of the vents.

Is it just moisture? Or AC refrigerant that leaks into air stream?

It was raining and I'm at Chicago suburbs.

My car is 1996 civic LX (125,000 Mi).

Thanks in advance.
Jay K

Sounds like condensation from the AC during a high humidity spell. If it
continues and is a refrigerant leak you will notice a degradation in your
ACs ability to "generate cool". If your AC continues to operate normally,
then obviously you're not losing refrigerant.

Second that. It is not unusual for fog to come out of the vents when
the humidity is high.

Especially if your A/C is working at top efficiency<g>

You may be a wee tad low on refrigerant. Normally, you shouldn't
see much fog, even with high humidity. Why? with the proper
charge, usually the coil temp is high enough to avoid blowing fog.
In most cases, blowing fog is due to being slightly low on charge.
This causes the coil temp to drop below freezing, and hence, you
see fog. If charged back up, the coil temp rises above freezing, and
no more fog. Better cooling too...

I concur with the other replies. Moisture did not condense on your
hand, because your hand is warmer than the air from the vent.
