Probably deserves a separate thread but I have trouble figuring HVAC out. From OFF if I start the fan I expect air from vents neither heated or cooled. I get heat or cool depending on temp set. IC starts and I get heat from the vents or the AC starts and cools the air. IF the AC runs, the AC light doesn't light.
Even after reading the manual, I've taken to setting a temp, deselecting recirculation and just letting it do its thing.
