I noticed walking from my car this morning when I got to work that there was a small trail of water. I looked underneath and there was water dropping from an exhaust pipe near the the oil pan, transmmission pan area. The water didn't seem to have any smell or slippery like coolant. The car was not running hot.

I was not running the Air this morning but did have the heat on up to about 10 minutes prior to pulling in and noticing the water.

 

If you used the defrost I believe it kicks the A/C on (at least it used to in my older cars) could still be from that or maybe jut water in the cowl area finally draining out through the drain holes.

 

The defrost will kick the A/C on like Frat-man-du said. Do you have the auto climate control? I think that with the auto climate control the A/C compressor is always running.
