2009 Avalanche 1500 - Kinda odd - the compressor never turns on when the 'fresh air' light is on., Pressing the recirc kicks on the compressor. Doesn't get really cold though. low side at about 45, high side at 195. Wondering if I have more than 1 issue. Lines get cold, seem fine. Lots of condensation - when sitting in humid conditions plenty of water coming off the lines. Plenty of air, just not ice cold, only when in recirc mode though. Wondering if maybe blend doors are partially open so not doing a full recirc. Driver and passenger side are both the same temp though. Any ideas?
