A/C compressor still operate while it's freezing cold outside
Hello,
The A/C compressor is supposed to only operate when outside air temperatures are above approximately 45 ̊F (7 ̊C).
But this winter I just realized that A/C compressor is still running while temperatures outside are way below 45 ̊F (7 ̊C), it's freezing outside.
I can hear the A/C clutch and radiator fan turning ON. They regularly turn OFF a few seconds and then turns ON again.
What can be faulty to keep A/C compressor operating below 45 ̊F (7 ̊C) ?
Temperature is correctly displayed inside the car, but I don’t know if the display and the A/C are using the same temperature sensor.
Thanks for your help.

Ok I dont see anything about the AC not turning on when the outside temp is below any certain temp. I would guess the AC cycling switch would be at fault. Honestly this vehicle is older so the publications are not very detailed.

I think concourse 50 is on the money !
A lot of automotive A/C systems use the A/C compressor system in the defrost mode to assist drying the windshield.,
The function selector sends heated and dried air to assist drying the windshield. All considered normal.
