2001 convert AC light comes on at strange times even in cold 40 deg weather. Auto or Manual mode makes no difference. Doesnt seem to be blowing cold air but light is on occasionally.

 

The AC runs automatically to dehumidify the interior. If it seems to do its own thing that's because its programmed that way so don't worry.

Below 36 degrees (IIRC) the AC is inhibited and will not run. The AC light flashes as a warning.

 

Thanks for the response. Thats what I suspected.
