AC question

[ArtHummer]

I think I noticed it before but didn't pay much attention to it till now.

So, I turned on the HVAC fan, set the airflow to leg and face, set the temp to 90% cold, the air is in recirculate inside the cabin and the AC button is off (the light is not on on the knob). In my understanding if the AC button switch is not 'ON' the AC should not work, but in my case the AC is working. I looked in to it more and what happens is, when the air is on recirculate and it blows on face or face&legs or windshield the AC is on even when the AC switch is OFF.
Is this a normal behavior? Can this be programed somehow to disable the AC at all times when the AC switch is OFF?

Mine does the same thing, if i have the car in park and idling i can turn the fan on and when i do the ac compressor kicks in even though i have the ac button off and the light for the ac is off too. I think thats "normal". Even when driving if i just turn the fan speed dial to 1 i can feel the compressor kick in and the car gets sluggish.

A/C kicks on in three situations: 1) A/C button is on. 2) Recirculate button is on. 3) Defrost is selected

The A/C Compressor will run in the three different modes that Alex described..

A/C kicks on in three situations: 1) A/C button is on. 2) Recirculate button is on. 3) Defrost is selected

that is just how it works and nothing is wrong.

Is there a way to disable the 2 and 3?
I don't know, call me an old school, but I prefer to have my own head to decide when the AC should be on.

Also, come to think of it. Will the AC kick on when you turn on recirculate and turn the temperature knob on hot? Does the situation 2 mean that my AC is running during winter when I try heat up my cab?
