Air Conditioner kick-in??

[churp]

Driving today with the window down and noticed cold air coming out the vents. My grandaughter had been in the car yesterday playing and I noticed the heat control turned to defroster....does the Yaris kick in the compressor ocassionally while in defroster mode? I know GM does or used to...so if anyone knows for sure let me know. I don't want the air taking the milage down unless I want it to.

Defrost mode settings (there are two on my car) do involve the A/C:smile:.

I noticed the same thing the other night. AC was off but I had it in defrost mode amd noticed the air was very cool coming out.
