After 8 months with my 2018 Model S100D, I still can't understand how the climate control system works! Sometimes the AC compressor button is lit blue (On), sometimes it's white (Off), and sometimes it's light blue (Huh?). In AUTO mode, the AC cooling always turns on immediately after I enter the car in the cold winter months but never turns on in the hot summer months - requiring me to override the setting every time I get in the car. (It's not because the compressor needs to be on for defogging). For example, it's 48 degrees right now in Chicago and my set point is 72 degrees. As soon as I enter the vehicle, the AC cooling starts blasting cold air until I intercede by manually turning off the AC and manually raising the set point to something above 80. Only then, will the cabin begin to warm even after 30+ minutes of driving. The opposite happens in the summer - as soon as I enter the car, the heat starts blasting until I manually lower the set point (from 72 degrees) and manually turn on the AC switch. Is my climate system wired incorrectly? I'm just noticing the partially lit AC button in the climate settings and wonder what it means (no, it's not in the manual). Ironically, if I set the cabin temperature to match the outside temperature, only then does the cabin stay comfortable. That is, since it's 48 degrees outside, I set the climate to 48 and I'm comfortable throughout my trip. I'm leaving shortly on a four week road trip out west and can't imagine setting my temperature to 100 degrees just to stay comfortable. There are a lot of bright minds in this forum - who has a thought as to what's happening here? Thanks in advance!
