    New wrinkle in HVAC

    After a week of noticing the air conditioner, here in sunny SW Florida, seemed to be intermittently blowing warmer than it ought to have, we got a notice on the screen saying HVAC system needed dealer service, and stopped working all together., this on last Friday evening.

    Late 2021 onwards MIC Model 3s Have poor/faulty air conditioning from factory

    After 4 Months of sending my Model 3 (December 2021, china factory) back to the service center for blowing on my knees and being told that "nothing was wrong" and everything being correct in the dash, it turns out that I was just the first of people noticing that the Model 3 with the new Heat...

    Don't want heater on, want vent

    Afternoon is still warm enough to require AC. Next morning I keep forgetting and after about 10 minutes of driving I realize heater is on. It is around 62 degrees out which is lower than the 72 degree setting in the car. In that scenario I don't want heater! I want vent. Keep the car cool until...
