Okay, so I'm an eco nerd and hate the impact that driving in the winter has. I've had my Model 3 through 4 winters now and just today (with the help of the Scan My Tesla app) did I discover that you can go manual temperature control, split the HVAC for left/right controls, set the passenger side to "LO" and it will fully disable the passenger half of the PTC heater and thereby halve the max draw of the heater. This way you can have warm air blowing on only the driver and recirculated air blowing on the empty passenger seat.
To recap:
The only catch is that if you need to enable the AC for defogging then the passenger side will try to cool toward the "LO" temperature setting.
I really wish that there was a "driver only" mode for the HVAC.
This is for a 2018 non-heat pump car, BTW.
To recap:
- Split HVAC into left/right control
- Disable auto climate
- Set passenger side to "LO"
- Set driver side to desired temperature
