Boomer,
When I change the temp or the fan setting the display shows the status (A/C status and fan speed). The status says A/C Off. My assumption was the A/C compressor is not running as the display says A/C Off and the light for the A/C on the climate control is also off. However, the temp of the vent air on the LO temp setting is very cold. I agree with the comments above, if you set the temp on 61 instead of LO the air temp is noticeably warmer. Likely the compressor is running when the temp is set to LO regardless of what the system status says.
Gee. Mine is not like that. When set at LOW and fan off, defrost off, auto off no cold air. Actually I haven't noticed the "display" telling me AC status and fan speed but maybe thats cause I usually just keep it in LO and off. I assume the "display" you refer to is the DIC or is it he infotainment screen? I have noticed I can get some warm air to circulate if I raise the temp setting with the fan off. So I guess that is slightly heated "fresh air" since there is no AC or fan going.
Page 8-5 of the Owners Manual says "If the fan is turned off the air conditioner will not run..." So if your AC is running with the fan off, maybe it should be checked.
This is interesting because a while back on a different thread, folks were complaining about HOT air coming in when they had the system off.
I am going to experiment with this issue on my next break-in drive when the wx clears. I haven't messed with the system enough to see what it really does. I don't even know what the "fresh air" setting is. I don't see such a setting. I just know when the system is set at LOW and fan off there is no cold or hot air.
