Air Conditioning 1592 air quality sensor, 1299 gateway
 

I have been having problems with my AC lately. it was not putting out very cold air when the setting was on Auto. I put the settings for climate control on LO and got it to blow cold air!! I measure the temperature at the vents and it is blowing out 43.8 degree F air.
Now sometimes in Auto settings and the temp set at 68 it blows cold air and not warm air.

Is it really the Air Quality Sensor or is it the Air Intake Sensor (under the cowl) that is bad or the Ambient Air Sensor (in by the cabin filter inside the car) ?
