why AC compress engaged when I switch to blow warm air to windshield.
I didn't notice this during summer. But now in winter here, when I start turning on heat/warm air, I notice other settings are working fine, but when I switch the setting to let warm air blow to the front windshield, I can hear the A/C compressor has been engaged as my AC compressor currently doesn't work and make a big noise. I know it is bad, I just don't want to fix it during the winter as I don't need it. But why it is engaged when in this one setting? I am sure I didn't turn on AC at all, and only warm air came out.
